@@cesar_m.p. You are absolutely right, I have been a pianist and keyboardist for 20 years but I took a break and I don't have a grand piano at home while almost two months ago I started again to play complex classical music with fast passages but I have a clavinova from the 90s that I felt so heavy and I have never felt so fatigued and with slight pain in the joint, I ordered the weight down from the C4 and it had 78 Grams !! but the surprise is that all the keys, including black, weigh the same, they are not even graduated, I went to a grand piano at my children's school and played like butter, the C4 downwards I only need 47 grams and the keyboard is obviously graduated. I felt bad in my old DP that I bought not long ago on eBay and I was almost on the verge of an injury I could say if I didn't stop, I tried the recommended Roland FP30x in a store and I felt the action was more relaxed and very good grip but I still felt it heavy for that repertoire, for softer repertoire it's super, the C4 below, low with 67 grams so I'm looking to invest in a better action that's more similar to a piano because we know it's not what yourself, what do you think about it? Greetings from Germany
Finally a video showing what visually happens. This was amazingly helpful and changed my decision in choosing the perfect piano for me. Thank you wholeheartedly.
This is EXTREMELY helpful. Amazing visuals and clear “instructions” if you will. I’ve been trying to develop my own 3D model of piano keys, but I’ve been stuck on how to get an action going on. This video really helped me visualize how these things work. Thanks so much
I ordered a kawai ca79 4 months ago and it’s still back ordered. A big reason why I ordered it is because of the action, so I’m just here watching videos on the action to feed my sadness and impatience haha
@@mmilrl5768 ….that’s what I’m concerned about….it might be next year. I don’t see any CA59’s anywhere around Chicago area. So….I sure won’t find a CA79.
Excellent explanation!... I was about to try to fix an electronic piano but had no idea about the differences between the different types of hammer actions... thank you very much for this valuable information!
It's been 2 months when I commented on your video for suggestion. I would like to thank you for giving me an idea of the Kawai digital piano actions. I purchased Kawai ES110 last week and I was really happy about it and with no regrets. Although I wish Kawai ES920 or ES520 was available on our region but ES110 is still an excellent choice for me. Before buying ES110 I did a lot of research and comparison. Side by side playing of the instrument and these were my observation. The ES110's key action is fully-weighted but slightly lighter than Yamaha's GHS action and Roland's PH4 action. But does not mean Kawai is behind the competition. If I rate the weight of these pianoes from 1-10 (10 the heaviest) 10. Roland FP-30 (PH4) 9. Yamaha P125 (GHS) 8.5 Kawai ES110 (RHC) 5. Yamaha DGX-230 (Semi-Weighted Graded Keys) I also included a Yamaha DGX keyboard to compare the weight as well from a fully weight digital piano and semi-weighted keyboard. RHC action feels like an upright acoustic piano but a little bouncy and short keybed. GHS feels like artificial and springy but it is somewhere in the middle of a grand and upright mechanism. PH4 with escapement feels like a grand piano but too heavy and can be too tiresome for hours but the ivory and ebony touches are its forte. But these actions that I mentioned are still acceptable and nice. The reason I purchased Kawai ES110 is the sound quality and sound sample plus the dynamic range. The RHC could be bouncy but still tolerable and forgiving and I also learned and practiced before piano on an old Kawai upright maybe that's why preferred Kawai. It could still be a personal preference since my teacher have Yamaha upright piano and also preferred a GHS action than RHC or PH4.
Great comparison. I would point out though that the GrandFeel Compact key length is the exact same as the RHIII if we measure it from the pivot point. Many prefer that RHIII action compared to the GFC.
Thanks for a very informative video. Just an FYI: in the synth/MIDI controller world the word semi-weighted implies that springs are used and there is no hammer action at all. I would suggest finding a different word to describe the RHC action in the future.
This is awesome. Do you have similar videos for other piano bed actions (Fatar, Yamaha etc)? Just off to check your channel videos. This should be standard content for these manufacturers. Once you are getting up to the price point that these boards go for I would expect most people would want to know all the details about how their prospective board works. Thank you for this content. Very clearly explained and very much appreciated.
The MP11SE is sold out everywhere in my country. Even the demo unit in the store near me just got sold yesterday and i cannot test it anymore! Although they do have the CA901 for demo it's quite a bit beyond my budget. 1. Is the GF3 on say a CA701/901 significantly better than the older GF on the MP11se? 2. Has the slip tape issue on the GF been addressed in factory?
Thanks for this excellent very detailed video. Frequently I've been asked to compare the actions of Kawai instruments after having bought a VPC1 last year and I've been unable to provide detailed answers, so I hope you don't mind if I reference this video next time I'm asked?
Thank you so much for this excellent video! What about the Kawai VPC1? Where does that action fall in this lineup? Thank you so much. - Andrew Colyer, New York
Thanks for your feedback! The VPC1 uses the RM3 Grand II action, which is an earlier version of the Grand Feel Action. So it would fall between the Grand Feel Compact and the Grand Feel action series. You can see a picture and a description of the RM3 Grand II action at this link: kawaius.com/technology/wooden-key-actions/
I hope the difference between the action of the MP11SE and the newer actions isn't that big, cause i want to buy the mp11se -and not wait for a follow-up model in the future :D
The Korg action is partially a spring loaded action. This is a very old design. The Kawai’s RHIII works purely on gravity as it is shown in this video.
You see that the key is "trembling" when she touches ( 03:06 ). That doesn´t happen on a real acoustic piano. I´m searching for an excellent piano action. It should have the acoustic touch, but I´ve played some Steinway pianos and the touch is excellent, very light, the fingers "fly" in speed, not as some acoustic pianos which are too hard and hurt my pulses and turns me lazy to play fast passages on classical music.
actually even acoustic piano trembles. search for video of Steinway action and you can see subtle trembling and even more on lesser brands. anyways, why even compare it with a Steinway that cost 30 times more? also in your own reply, you basically said not all acoustic pianos have the same action so by that account i am pretty confident you can find some others that "trembles" too
That's a great question! I have not seen a RM3 Grand II action in person, but from info on Kawai's website and in PianoManChuck's video, it looks like the RM3 uses similar components as the original Grand Feel Action, but has a shorter keystick. Hope this helps! kawaius.com/technology/wooden-key-actions/
The bounce of the hammer returning to rest kind of inhibits your ability to imagine how the key press might feel. At least for me. 3:05 looks cool though
Not one maker of actions quotes the note repetition rate of a single note, which as a pianist, I find terribly frustrating. Surely it should be a metric which accompanies any action sold? I have a bunch of Fatar TP/x 88noters here in Kurzweils, and they are all 2 switch, and (sorry Fatar), but for me they are too slow where note repetition is concerned (more like an upright cf. a grand), forcing ornaments instead. Is there a drop in upgrade for the action? Perhaps a nice Fatar triple switch GH action with >12notes/second repettition? Roll on the day when upgrading an action is a DIY exercise. It would be about time. Didn't do the PC market any harm to sell users the components to build their own.
I am afraid your information is not accurate. This is scaled/graded hammer weighted action and not semi weighted. The RHii has counter weights and triple sensors. The RHC is weighted with double sensors. Semi weighted is a term referring usually to piano like keys with springs in the back. (Spring based action)
That's an interesting thought! Having a full acoustic action like is in the NV5S and 10S requires more space, so I'm not sure if it could fit into a portable model like the vpc-1
Hi, can you tell me pls. how many grams weight have Kawai MP-11 keys downwards, and what is the max. repetition frequency in Hertz for this action (Kawai's Grand Feel compact action) (should be minimum 15 Hz)? Szabi from Transylvania
@@bayareamindandmusicsociety8020 First of all thank you sooo much for your efforts! Yes I meant down-weight of the keys. I dont get it yet, so is it 62 or is it 55 grams. Yes, by frequency I meant max. repetitions of key per second. The value 12 suprises me, grand acoustic pianos have 15 Hz. I heard the Kawai MP-11 has one of the heaviest keys, and I have weak fragile fingers. I am searching for a high-to-mid range digital piano, with the lightest keys (smallest down-weight), but the choice is really just between Roland PHA-50 and Kawai Grand Feel. Next september or christmas I am gonna have enough money to buy one. I did already a music school 25 years ago, that was synthesizer and for gigs, but now I want to do the classical pianist all the way to conservatory admission level. But I won't be a stage pianist, nor conservatory, I learn it for my own joy, so I can play pieces for myself and enjoy it. Thanks again for your efforts.
I wouldn't say a video that contains a few false claims is a good job. For example, false information that the GFII and GFIII actions have different length of keysticks. It is completely incomprehensible where this misconception could have come to mind.
Oleg Well, Louise mentioned that she doesn’t currently have access to a GFIII action sample, which may account for the key length inaccuracy. However, I maintain that the vast majority of information in this video is correct and clearly presented. “Don’t let perfect be the enemy of good” etc.
@@namakudamono I also never had access to a new action, but I knew from the first day of the announcement that in this regard, both actions are identical. You can also look at other comments here to understand that this was not the only inaccuracy in this short video. For a person representing Kawai instruments, this is critical. Need to prepare better. Or at least not invent something that doesn't exist.
I'm not sure! To my knowledge, other brands like Yamaha and Roland make digital pianos that use an action more similar to the RHIII but with wood veneers on the sides. I'm curious to hear what other commenters know!
Yes, I'd say the touch is similar. The KDP120 has a slightly more advanced action technically because of the triple sensor. The ES120 and KDP75 use the same action. The KDP75 and KDP120 have 15 sounds to choose from, while the ES120 has 25.
Does anyone know of the RHC action for the es110 uses Lead or steel as a weight? Tried to find info online but couldnt find any info about the material used in the action. Thus was a wery infornative video by the way. Thx. :)
Thank you so much for this video, which action would closely resemble an upright piano? Currently have a yamaha P125 but notice a big difference when I jump onto a real piano hence looking for recommendations.
An upright piano action is different than these actions that are modeled more after grand piano actions. An upright action features a mechanism where the hammer moves forward (rather than upward) to strike the string. I would look for a digital piano with a longer wooden keystick for a more even weight distribution as you go up and down the key.
Kawai uses the Millennium III action in their current production for acoustic pianos, and all their own models of digital key actions. I actually have not heard of Renner actions being used by Kawai before! What model of Kawai do you have that uses Renner?
Do these types of KAWAI mechanism have LEAD parts or as counterweights? I hope the Lead has been eliminated because it is toxic. In real wooden pianos (it seems to me more in the grand ones and less in the vertical ones, where perhaps they are not on the sides but more in depth) I have seen that on the sides the keys are full of these Lead button disc counterweights. What can You tell me? And which brands have banned it? Thank You.
To clarify, none of Kawai's digital piano actions use lead counterweights. Counterweights are typically made of lead or steel. Counterweights are placed inside of the key, meaning there is no possible contact with the person playing the piano. Lead poisoning can occur from lead getting into the body through water or food contamination or from breathing in dust from deteriorating lead-based paint. Lead poisoning does not occur from playing a piano that has lead or steel pieces built into its keysticks.
@@BayAreaPianoMasters , yes, I today played Kawai MP11SE - it is even quieter than CA901, because has no cabinet to resonate. Very quiet, gently and soft keyboard. Loved it from the first touch.
What about durability? Which kawai key action system will last the longest before one or more parts breaks or wears out? I have seen cases on other brands where one of the plastic components breaks (presumably from frequent use) resulting in the need for a replacement. And while I am on this subject, how easy is it to obtain spare parts in order to make repairs? I ask because I am thinking of purchasing the CA79 and would like to believe that the keys would last at least 10-15 years of regular use before they are damaged in this way. Currently, I own a Roland KR-570 purchased 20 years ago and only now are the plastic mechanisms beginning to fail.
my experience is rather limited, but putting aside failure of sensor and circuitry which there is no way to tell, I expect a Kawai action to be quite durable from a purely mechanical point of view. In fact the major manufacturers like Kawai, Yamaha and Roland use quite similar layout. if you look at the middle of the keys right above the sensor, the protruding plastic piece is pressed into a cup of sort. This seem to be a more robust design and easier to find a fix if it breaks. In my opinion, this type of design has the potential to be far more robust than Casio's design (google a video of their action to see what i mean) where a similar plastic protrusion is found but is used to house a rubber bits that drives the lever to hit the sensor. Damage to the rubber piece would cause the key to sink. There is much greater range of movement needed for the Casio design and putting a rubber knob over the plastic point meant that you probably need the exact part for replacement compared to the key-bed from the other companies where you just need to find something to line the cup. I think Casio's design is the closest to a "digitalization" of a acoustic piano as far as plastic action goes. But that is not to say that it is better simply because the pivot length is completely different. if we look at Kawai's Grand Feel action we can see how having long key length reduces the need for complexity which is not the case for Casio. The mechanical analysis is ofcoz my 2 cent worth and I would be glad to be proven wrong. But all that being said, I think the keys across all brands should be pretty robust and would last many years of use. But 10-15 years is really pushing it to be honest.
I play with KORG ex88 but I look for a new one with touch similar my ex upright piano. Vpc1 , or keyboard with PHA50 as Roland FP90X or NWX system? Could vpc1 be a good election ? I need only the keyboard without furniture and use Pianotec8. Thanks
I think the VPC1 or the MP11SE could be a good option for you! They both have the fully wooden keys with an extended length, so the touch is quite nice!
Hi, i am upgrading my keyboard to piano actions however i am lack of budget to buy an acoustic piano as advised by my piano teacher. May i know if ES110 type of action is sufficient for my finger touch and pressure training (as if i am playing an acoustic piano)?
I'm not sure which keyboard you're currently practicing on, but even though the ES110 has a more simple action, it has 88 grade-weighted keys. The keys are touch-responsive meaning that you can control the volume of the sound that's produced by pressing with more or less pressure with your fingers. What type of keyboard do you currently have?
@@pingchianleong2508 I think the es110 will be a nice upgrade in regards to the key-touch and weighting and because it has the full 88 keys. I hope you find a new keyboard that works well for you!
Is Kawai ES110 keys action are semi-weighted like the Yamaha DGX-530 keys? I owned a Yamaha DGX-220 with semi-weighted keys andI'm planning to buy a digital piano with weighted keys. One of my option is Kawai ES110.
I'm hesitant to use the term semi-weighted again (see the comments below). But in my opinion, the ES110 key action feels lightly weighted to me. If you're looking for a portable keyboard with a more advanced action with keys that are more weighted, I would recommend looking at the ES520 or 920. There is an increase in price point, but I would consider both the actions on these pianos to be better than that of the ES110.
@@BayAreaPianoMasters Thanks for the recommendation. When you mentioned that Kawai ES110 has a semi-weighted keys. I first thought that it was just the same with the Yamaha DGX-230/530 action as Yamaha stated on the paper.. Since I owned a Yamaha DGX-230 and wanted to upgrade to a digital piano with 88 weighted keys. I never tried or seen a Kawai digital piano( Although I was able to play on a Kawai Grand Acoustic Piano and Kawai Upright Piano) since it is not readily available on our region and we have to preorder it from a music shop. But ES110 was one of option second is a Yamaha P125 and Roland FP-30. I was able to play Roland FP-30 and Yamaha P125 which is also my options aside from Kawai ES110. But after watching several reviews about Kawai ES110. I was impressed with its dynamic range and sound but the downside is the light keys. Which made me wonder on "How light are the keys? is it the same as the the Yamaha DGX-230/530 model which I owned right now". I might reconsider to upgrade to a higher version if I will not be impress by the keys and action after seeing and touching it personally.
@@doremifasollatido2255 I haven't done a comparison between the Yamaha and Roland models and the ES110, so I'm not sure how the feeling of the keys compare. Our store just carries Kawai at this time, so that's all I have readily available to me. In any case, it sounds like you're doing a lot of research, so I hope you find a piano that works well for you!
Yes. You should know that even all acoustic pianos have different weight and tone. So is never gonna be the same. Some pianos can be adjusted to a lighter key action.
@@ispianist doesn't matter. The grand feel action 3 is what it is, unsubstantial, unrealistically light, spongy, not firm. It's true every acoustic is different, but there are not acoustic lighter or more or spongy as the kawai GF3. No you can't change the action, the weight of the keys of a digital piano action can't change. I suppose you mean the touch response, that basically it changes the touch force required to obtain the same sound. But that is not the weight of the keys that changes.
@@verymozart No I meant the weight when your press the keys on acoustic piano. Yes you can change that. I've done that couple times. These pianos truly feel like a grand piano. I have played with many Steinway pianos and I own myself the Studiologic GT. The feel is very similar when you press the keys. On the other hand the sound is not the same. But I use VST.
@@ispianist but the grand feel 3 action is quite rubbish, it's all but an acoustic feel.. It's like a toy, nothing to do with an acoustic piano touch action
Thanks for your comment. I used the phrase "semi-weighted" to highlight that the weighting of the RHC is different than that of the RHIII. Eric (the commenter above) offered a similar suggestion, and I appreciate the feedback.
I read that the hammer action of the keys of KAWAI KDP 120 is just basic. So not the best for advanced pianists. Is that true? Are the key too softly weighted for advanced classical music piano practice??
I agree that the KDP120 action is more basic--it uses Kawai's Responsive Hammer Compact II Action (which is a predecessor to Kawai's most current plastic key action, the Responsive Hammer III). If you're looking for a higher quality action, I would recommend the CA49 since it is still at somewhat of a mid-range price point and uses longer wooden keysticks.
@@BayAreaPianoMasters CA 49, you think is fine for advanced practice? But it's expensive for my budget, even because you have to include the costs of the stool, the headphone and to install it it costs as far as £ 250. I saw now there's a bit cheaper Kawai CN39, that states has hammer action III, but l don't know. Or maybe Kawai CN29? I'm a bit discouraged honestly, because it seems l won't find a digital piano for my needs within my budget 😔. Thanks for your reply
@@verymozart The piano bench comes in the bundle with the CA49, but, yes, headphones would be an additional cost. In the U.S., the CA49 retails for $2299 USD and the CN29 retails for $1959 USD. (I have a CA49 at home, and I completed the assembly with 1 other person on our own. It's a little time-consuming, but it can be done :) ). The CN29 and CN39 use the same action--the 39 has upgrades to the speakers, sound selection, and the Bluetooth connection. I'm not sure what your budget is, but purchasing a portable piano will typically bring down the cost of the piano. The Kawai ES920 uses the same action as the CN29 and 39, but it costs $1599 USD. It doesn't come with a stand and bench, though. Even though the KDP120 has a more basic action, it still is better than the action of the ES110 (which uses Kawai's most basic action, the Responsive Hammer Compact). Hope this helps!
@@BayAreaPianoMastersthanks for replying. I think KDP 120 is too entry level and the Hammer action too basic for advanced practice. O can't afford CA 49. All l'm trying to find out now is if the CN39 (with Hammer Action III, full weighted keys, and high polyphony 255,) is appropriate for advanced classical music piano practice. That would be within my budget. I found a dealer here in the UK with a nice price, included: bench headphone, 5 yrs guarantee, (plus £180 to assemble/install it, l live alone and can't assemble the top without someone else). And in 3 interests free payments.
Very nice, As an Acoustic Piano Tech I'm having a hard time finding anything on the older Kawai CP series actions with some of the first wooden keys. I need to find the plastic parts that the counter weights pivot in For a CP-150 . As well as the pads if still available. Besides the broken part some of the notes sound louder then others, I think that is the pads or just dirty. Any help pointing me in the right direction would be appreciated.
In regards to the some notes sounding louder than others, it sounds like there is an issue with some of the sensors. I am not sure where you're located but you may try contacting the parts department at Kawai directly for the parts you are in need of. You can ask for David Reed and see if he can assist you. Kawai's number is listed on their website.
San Mateo Piano: Thank’s for this. How did you get this information? Did you remove the top of the piano. I used calipers on supposed scale drawing in a brochure. By so doing, I “calculated” 16.9 inch keys. They do fit the sanity check. I’m very curious. On a total other key length subject: I measured the keys on the KAWAI GL series grands. The key length on the 5’2” baby grand are 20”. The key length on the SS Model “M” is 19” and on the BOSTON’s is 18.9”. (Ken length contributes to the ability of playing pp and ppp passages more responsively. (BTW, 19” is a VERY adequate length.) Long is good - but has to be merged with a good action, of course.
@@kenpeters9807 I would definitely need a technician's help to remove the top of the piano! I measured the GF2 action model that we were sent by Kawai. Thanks for that additional information about the keystick lengths for the acoustic pianos!
It's all about what do you want it for. There are keyboards designed to be light to touch but have the fastest "reset" moving up so you can play it repeatedly easier, great for electronic music and organ playing, awful feeling for classical players. Newer tech made cheaper actions feel closer and closer to real acoustic pianos. To the extreme of some hybrid pianos having the same keyboard mechanisms as a concert grand, but using sensors instead of strings. Not cheap tech, but really advanced!

Thank you for your kind words! Glad that you're enjoying the videos.
It's been 2 months when I commented on your video for suggestion. I would like to thank you for giving me an idea of the Kawai digital piano actions.
I purchased Kawai ES110 last week and I was really happy about it and with no regrets. Although I wish Kawai ES920 or ES520 was available on our region but ES110 is still an excellent choice for me.
Before buying ES110 I did a lot of research and comparison. Side by side playing of the instrument and these were my observation.
The ES110's key action is fully-weighted but slightly lighter than Yamaha's GHS action and Roland's PH4 action. But does not mean Kawai is behind the competition.
If I rate the weight of these pianoes from 1-10 (10 the heaviest)
10. Roland FP-30 (PH4)
9. Yamaha P125 (GHS)
8.5 Kawai ES110 (RHC)
5. Yamaha DGX-230 (Semi-Weighted Graded Keys)
I also included a Yamaha DGX keyboard to compare the weight as well from a fully weight digital piano and semi-weighted keyboard.
RHC action feels like an upright acoustic piano but a little bouncy and short keybed.
GHS feels like artificial and springy but it is somewhere in the middle of a grand and upright mechanism.
PH4 with escapement feels like a grand piano but too heavy and can be too tiresome for hours but the ivory and ebony touches are its forte.
But these actions that I mentioned are still acceptable and nice.
The reason I purchased Kawai ES110 is the sound quality and sound sample plus the dynamic range.
The RHC could be bouncy but still tolerable and forgiving and I also learned and practiced before piano on an old Kawai upright maybe that's why preferred Kawai.
It could still be a personal preference since my teacher have Yamaha upright piano and also preferred a GHS action than RHC or PH4.
Thank you for your detailed comment! I'm glad that the ES110 is working well for you!
You deserve more subs. If i see how much efoort you have puy in this video. Very nice and ibteresting 💯👌🏾
Interesting to see these models and learn about the differences. I will be saving for C79 or C99 then.
I've really enjoyed playing on both those models, so I hope either one is a good fit for you! Thanks for watching :)
Great comparison. I would point out though that the GrandFeel Compact key length is the exact same as the RHIII if we measure it from the pivot point. Many prefer that RHIII action compared to the GFC.
Great explanation and demonstration, thank you very much!
Thank you for your feedback!
VERY VERY PROFESIONAL & DETAILED EXPLANATION....THANK YOU !!!!
Thanks for a very informative video. Just an FYI: in the synth/MIDI controller world the word semi-weighted implies that springs are used and there is no hammer action at all. I would suggest finding a different word to describe the RHC action in the future.
Thanks for that feedback! What you're saying makes sense. I am still learning, and appreciate the correction.
Nice video. I could listen to you talk all day. What a beautiful tone of voice you have, and I love the blue hair. :)
Thank you
Thanks for sharing it. Really well-detailed and informative video.
Thank you for watching!
This is awesome. Do you have similar videos for other piano bed actions (Fatar, Yamaha etc)? Just off to check your channel videos. This should be standard content for these manufacturers. Once you are getting up to the price point that these boards go for I would expect most people would want to know all the details about how their prospective board works. Thank you for this content. Very clearly explained and very much appreciated.
Yes comparing these would be very helpful!
Excellent presentation. Thank you!
Glad it was helpful!
very informative. thanks for this!
Thank you for watching!
The MP11SE is sold out everywhere in my country. Even the demo unit in the store near me just got sold yesterday and i cannot test it anymore!
Although they do have the CA901 for demo it's quite a bit beyond my budget.
1. Is the GF3 on say a CA701/901 significantly better than the older GF on the MP11se?
2. Has the slip tape issue on the GF been addressed in factory?
Thank you for the excellent explanation!
After watching this video, i decided to buy steinway model D grand piano..thank you
Wow 🤩 What an interesting video! I have a Yamaha piano but this is so cool! 😁
Thanks for watching!
Excellent detailed video thank you so much.

Hi, can you do Yamaha Action comparison?
Unfortunately, I don't have access to Yamaha actions at this time
Thanks for this excellent very detailed video. Frequently I've been asked to compare the actions of Kawai instruments after having bought a VPC1 last year and I've been unable to provide detailed answers, so I hope you don't mind if I reference this video next time I'm asked?
Very informative. Great keyfeel topic.🎹👍
Hi, is there any place that i can buy those physical action models?
To my knowledge, these are just sent to piano dealers as promotional materials. So I don't think they're available for purchase anywhere.
Very interesting. Thank you. It would also be useful to make a comparison of yamaha action.
We sell only Kawai pianos at this time, but I agree, that would be useful!
Yamaha sadly doesn't provide much informations about their actions, beside the name.
very good, very clear explanation, thanks so much, do you have Yamaha's Graded Hammer demo?
I wish! I have yet to come across any Yamaha action demos.
thanks for this
glad it was helpful!
Fantastic video. Thank you.,
Thanks for watching!
Thank you so much for this excellent video! What about the Kawai VPC1? Where does that action fall in this lineup? Thank you so much. - Andrew Colyer, New York
Thanks for your feedback! The VPC1 uses the RM3 Grand II action, which is an earlier version of the Grand Feel Action. So it would fall between the Grand Feel Compact and the Grand Feel action series. You can see a picture and a description of the RM3 Grand II action at this link: kawaius.com/technology/wooden-key-actions/
Well explained, thanks
Big thanks for this video!!!!!🥰
I hope the difference between the action of the MP11SE and the newer actions isn't that big, cause i want to buy the mp11se -and not wait for a follow-up model in the future :D
Thanks for uploading
The Korg action is partially a spring loaded action. This is a very old design.
The Kawai’s RHIII works purely on gravity as it is shown in this video.
Thanks for your insights!
You see that the key is "trembling" when she touches ( 03:06 ). That doesn´t happen on a real acoustic piano. I´m searching for an excellent piano action. It should have the acoustic touch, but I´ve played some Steinway pianos and the touch is excellent, very light, the fingers "fly" in speed, not as some acoustic pianos which are too hard and hurt my pulses and turns me lazy to play fast passages on classical music.
actually even acoustic piano trembles. search for video of Steinway action and you can see subtle trembling and even more on lesser brands. anyways, why even compare it with a Steinway that cost 30 times more? also in your own reply, you basically said not all acoustic pianos have the same action so by that account i am pretty confident you can find some others that "trembles" too
Very informative Video. So thanks for this. Where do you rate the action of the VPC-1 (RM3 Grand II) ✌🏼
That's a great question! I have not seen a RM3 Grand II action in person, but from info on Kawai's website and in PianoManChuck's video, it looks like the RM3 uses similar components as the original Grand Feel Action, but has a shorter keystick. Hope this helps! kawaius.com/technology/wooden-key-actions/
@@BayAreaPianoMasters Thanks! Interesting! ✌🏼
Amazing video. Thank a lot.
At 42 seconds, the hammer is bouncing after it has struck, The action needs regulating. The set off is happening too late.
The bounce of the hammer returning to rest kind of inhibits your ability to imagine how the key press might feel. At least for me. 3:05 looks cool though
the said bounce is not uncommon even on grand piano
Not one maker of actions quotes the note repetition rate of a single note, which as a pianist, I find terribly frustrating. Surely it should be a metric which accompanies any action sold? I have a bunch of Fatar TP/x 88noters here in Kurzweils, and they are all 2 switch, and (sorry Fatar), but for me they are too slow where note repetition is concerned (more like an upright cf. a grand), forcing ornaments instead. Is there a drop in upgrade for the action? Perhaps a nice Fatar triple switch GH action with >12notes/second repettition? Roll on the day when upgrading an action is a DIY exercise. It would be about time. Didn't do the PC market any harm to sell users the components to build their own.
RHC is not Semi-weighted, it is graded hammer weighted
I am afraid your information is not accurate. This is scaled/graded hammer weighted action and not semi weighted. The RHii has counter weights and triple sensors. The RHC is weighted with double sensors. Semi weighted is a term referring usually to piano like keys with springs in the back. (Spring based action)
Thanx for making this video
Thank you for watching!
Hi. I like your videos. Very informative! Would you mind making a similar video for the Yamaha digital piano actions?
Thanks for watching! If I had access to Yamaha actions, I would love to. But the store I work for specializes in Kawai only.
@@BayAreaPianoMasters i wamted to ask yhr same thing
I'd really like to see Kawai produce a version of the vpc-1 with a real grand action like their novus hybrids.
That's an interesting thought! Having a full acoustic action like is in the NV5S and 10S requires more space, so I'm not sure if it could fit into a portable model like the vpc-1
Hi, can you tell me pls. how many grams weight have Kawai MP-11 keys downwards, and what is the max. repetition frequency in Hertz for this action (Kawai's Grand Feel compact action) (should be minimum 15 Hz)?
Szabi from Transylvania
I will have to get back to you on this! Any info I find out, I will post here.
@@bayareamindandmusicsociety8020 First of all thank you sooo much for your efforts! Yes I meant down-weight of the keys. I dont get it yet, so is it 62 or is it 55 grams. Yes, by frequency I meant max. repetitions of key per second. The value 12 suprises me, grand acoustic pianos have 15 Hz. I heard the Kawai MP-11 has one of the heaviest keys, and I have weak fragile fingers. I am searching for a high-to-mid range digital piano, with the lightest keys (smallest down-weight), but the choice is really just between Roland PHA-50 and Kawai Grand Feel. Next september or christmas I am gonna have enough money to buy one. I did already a music school 25 years ago, that was synthesizer and for gigs, but now I want to do the classical pianist all the way to conservatory admission level. But I won't be a stage pianist, nor conservatory, I learn it for my own joy, so I can play pieces for myself and enjoy it. Thanks again for your efforts.
And you are beautiful..
which action system on the market now has the most true-to-life (i.e. real grand) action?
Good job Louise! Clear and informative explanation. Hopefully Kawai America can send you a GFIII action sample soon!
I wouldn't say a video that contains a few false claims is a good job. For example, false information that the GFII and GFIII actions have different length of keysticks. It is completely incomprehensible where this misconception could have come to mind.
Oleg Well, Louise mentioned that she doesn’t currently have access to a GFIII action sample, which may account for the key length inaccuracy. However, I maintain that the vast majority of information in this video is correct and clearly presented. “Don’t let perfect be the enemy of good” etc.
@@namakudamono I also never had access to a new action, but I knew from the first day of the announcement that in this regard, both actions are identical. You can also look at other comments here to understand that this was not the only inaccuracy in this short video. For a person representing Kawai instruments, this is critical. Need to prepare better. Or at least not invent something that doesn't exist.
Iam going to get CA17 with RM3 Grand II, what actually will this key action perform compare to those in the videos? Thank you
Which other brands, not Kawaii, features that nice "grand feel action" keybed? The ones with long keys.
I'm not sure! To my knowledge, other brands like Yamaha and Roland make digital pianos that use an action more similar to the RHIII but with wood veneers on the sides. I'm curious to hear what other commenters know!
Thank you!
Is it ES120 and KDP75, KDP120 almost the same piano feeling and sound when play ?
Yes, I'd say the touch is similar. The KDP120 has a slightly more advanced action technically because of the triple sensor. The ES120 and KDP75 use the same action. The KDP75 and KDP120 have 15 sounds to choose from, while the ES120 has 25.
Does anyone know of the RHC action for the es110 uses Lead or steel as a weight? Tried to find info online but couldnt find any info about the material used in the action.
Thus was a wery infornative video by the way. Thx. :)
It doesn't contain lead:) I wrote to Kawaii and asked.
Thank you so much for this video, which action would closely resemble an upright piano? Currently have a yamaha P125 but notice a big difference when I jump onto a real piano hence looking for recommendations.
An upright piano action is different than these actions that are modeled more after grand piano actions. An upright action features a mechanism where the hammer moves forward (rather than upward) to strike the string. I would look for a digital piano with a longer wooden keystick for a more even weight distribution as you go up and down the key.
We own a Kawaii manufactured piano that has a Renner piano action. Are these still used in currently manufactured pianos?
Kawai uses the Millennium III action in their current production for acoustic pianos, and all their own models of digital key actions. I actually have not heard of Renner actions being used by Kawai before! What model of Kawai do you have that uses Renner?
@@BayAreaPianoMasters The Kawaii manufactured piano with the Renner piano action was sold under the brand Scheidmayer. So it was in North America.
Do these types of KAWAI mechanism have LEAD parts or as counterweights?
I hope the Lead has been eliminated because it is toxic.
In real wooden pianos (it seems to me more in the grand ones and less in the vertical ones, where perhaps they are not on the sides but more in depth) I have seen that on the sides the keys are full of these Lead button disc counterweights.
What can You tell me? And which brands have banned it?
Thank You.
To clarify, none of Kawai's digital piano actions use lead counterweights.
Counterweights are typically made of lead or steel. Counterweights are placed inside of the key, meaning there is no possible contact with the person playing the piano.
Lead poisoning can occur from lead getting into the body through water or food contamination or from breathing in dust from deteriorating lead-based paint. Lead poisoning does not occur from playing a piano that has lead or steel pieces built into its keysticks.
So the CA77 and CA79 uses te grand feel action 3? CA78 and 98 uses grand feel 2?
CA78/98 use Grand Feel 2; CA79/99/701/901 use Grand Feel 3
Superb content
Thank you!
How much noise actions produce? I need the quiter one to play in headphones without boring other people in the room.
The CA piano actions (GFC and Grand Feel III) are the quietest! If you're wanting more info, feel free to email me at specials@sanmateopiano.com
@@BayAreaPianoMasters , yes, I today played Kawai MP11SE - it is even quieter than CA901, because has no cabinet to resonate. Very quiet, gently and soft keyboard. Loved it from the first touch.
which system is better?
What about durability? Which kawai key action system will last the longest before one or more parts breaks or wears out? I have seen cases on other brands where one of the plastic components breaks (presumably from frequent use) resulting in the need for a replacement. And while I am on this subject, how easy is it to obtain spare parts in order to make repairs? I ask because I am thinking of purchasing the CA79 and would like to believe that the keys would last at least 10-15 years of regular use before they are damaged in this way. Currently, I own a Roland KR-570 purchased 20 years ago and only now are the plastic mechanisms beginning to fail.
my experience is rather limited, but putting aside failure of sensor and circuitry which there is no way to tell, I expect a Kawai action to be quite durable from a purely mechanical point of view. In fact the major manufacturers like Kawai, Yamaha and Roland use quite similar layout. if you look at the middle of the keys right above the sensor, the protruding plastic piece is pressed into a cup of sort. This seem to be a more robust design and easier to find a fix if it breaks.
In my opinion, this type of design has the potential to be far more robust than Casio's design (google a video of their action to see what i mean) where a similar plastic protrusion is found but is used to house a rubber bits that drives the lever to hit the sensor. Damage to the rubber piece would cause the key to sink. There is much greater range of movement needed for the Casio design and putting a rubber knob over the plastic point meant that you probably need the exact part for replacement compared to the key-bed from the other companies where you just need to find something to line the cup.
I think Casio's design is the closest to a "digitalization" of a acoustic piano as far as plastic action goes. But that is not to say that it is better simply because the pivot length is completely different. if we look at Kawai's Grand Feel action we can see how having long key length reduces the need for complexity which is not the case for Casio.
The mechanical analysis is ofcoz my 2 cent worth and I would be glad to be proven wrong. But all that being said, I think the keys across all brands should be pretty robust and would last many years of use. But 10-15 years is really pushing it to be honest.
Don't do it, purchased CA78, developed problem with sticking keys after 2 and half years, support from Kawai very bad.
Do you have this for Korg, Roland, and Yamaha?
I wish! We are a Kawai dealer, so we do not have access to action models of other brands.
What action does the Kawai Pw 300 have??
Hey, just wanna ask where and how can you buy those keys? Please reply, I want to get one. Thanks
I'm also interested:-)
To my knowledge, the key action models are only available to Kawai piano dealers.
I play with KORG ex88 but I look for a new one with touch similar my ex upright piano. Vpc1 , or keyboard with PHA50 as Roland FP90X or NWX system? Could vpc1 be a good election ? I need only the keyboard without furniture and use Pianotec8. Thanks
I think the VPC1 or the MP11SE could be a good option for you! They both have the fully wooden keys with an extended length, so the touch is quite nice!
@@BayAreaPianoMasters thank you. Do you know if vpc1 has problems with the pedals? I have seen several comments about it
Interesting video!
Thanks for watching!
Is the casio px 160 RHC hammer action
Nice video. How about kpd 120? Thank you
The KDP120 uses the RHCII. It is like the RHC, but it has a triple sensor and an improved cushion material.
The RHC is nicely weighted. It is misleading to claim that it is almost unweighted.
Hi, i am upgrading my keyboard to piano actions however i am lack of budget to buy an acoustic piano as advised by my piano teacher. May i know if ES110 type of action is sufficient for my finger touch and pressure training (as if i am playing an acoustic piano)?
I'm not sure which keyboard you're currently practicing on, but even though the ES110 has a more simple action, it has 88 grade-weighted keys. The keys are touch-responsive meaning that you can control the volume of the sound that's produced by pressing with more or less pressure with your fingers.
What type of keyboard do you currently have?
@@BayAreaPianoMasters a very old casio wk1800
@@pingchianleong2508 I think the es110 will be a nice upgrade in regards to the key-touch and weighting and because it has the full 88 keys. I hope you find a new keyboard that works well for you!
@@BayAreaPianoMasters thank you very much for your advice!
I read that the MP12 will have GF 3 action when it comes out next year. Rumor or possibly true?
I haven't heard about that, but I think it would be a smart move on Kawai's part to do that!
Is Kawai ES110 keys action are semi-weighted like the Yamaha DGX-530 keys? I owned a Yamaha DGX-220 with semi-weighted keys andI'm planning to buy a digital piano with weighted keys. One of my option is Kawai ES110.
I'm hesitant to use the term semi-weighted again (see the comments below). But in my opinion, the ES110 key action feels lightly weighted to me. If you're looking for a portable keyboard with a more advanced action with keys that are more weighted, I would recommend looking at the ES520 or 920. There is an increase in price point, but I would consider both the actions on these pianos to be better than that of the ES110.
@@BayAreaPianoMasters Thanks for the recommendation. When you mentioned that Kawai ES110 has a semi-weighted keys. I first thought that it was just the same with the Yamaha DGX-230/530 action as Yamaha stated on the paper.. Since I owned a Yamaha DGX-230 and wanted to upgrade to a digital piano with 88 weighted keys. I never tried or seen a Kawai digital piano( Although I was able to play on a Kawai Grand Acoustic Piano and Kawai Upright Piano) since it is not readily available on our region and we have to preorder it from a music shop. But ES110 was one of option second is a Yamaha P125 and Roland FP-30.
I was able to play Roland FP-30 and Yamaha P125 which is also my options aside from Kawai ES110. But after watching several reviews about Kawai ES110. I was impressed with its dynamic range and sound but the downside is the light keys. Which made me wonder on "How light are the keys? is it the same as the the Yamaha DGX-230/530 model which I owned right now". I might reconsider to upgrade to a higher version if I will not be impress by the keys and action after seeing and touching it personally.
@@doremifasollatido2255 I haven't done a comparison between the Yamaha and Roland models and the ES110, so I'm not sure how the feeling of the keys compare. Our store just carries Kawai at this time, so that's all I have readily available to me. In any case, it sounds like you're doing a lot of research, so I hope you find a piano that works well for you!
0:08 where can i buy these salesman kawaii key samples ?
They're not for sale, unfortunately. They are sent to Kawai dealers as promotional materials.
Wonder if anybody know differences between kawaii RHC and the Korg RH3 action. I am between Korg lp380 and kawaii kdp75
Is the Grand Feel III suitable for practicing advanced level of classical music in order to study for diploma level??
Yes. You should know that even all acoustic pianos have different weight and tone. So is never gonna be the same. Some pianos can be adjusted to a lighter key action.
@@ispianist doesn't matter. The grand feel action 3 is what it is, unsubstantial, unrealistically light, spongy, not firm. It's true every acoustic is different, but there are not acoustic lighter or more or spongy as the kawai GF3. No you can't change the action, the weight of the keys of a digital piano action can't change. I suppose you mean the touch response, that basically it changes the touch force required to obtain the same sound. But that is not the weight of the keys that changes.
@@verymozart No I meant the weight when your press the keys on acoustic piano. Yes you can change that. I've done that couple times. These pianos truly feel like a grand piano. I have played with many Steinway pianos and I own myself the Studiologic GT. The feel is very similar when you press the keys. On the other hand the sound is not the same. But I use VST.
@@ispianist but the grand feel 3 action is quite rubbish, it's all but an acoustic feel.. It's like a toy, nothing to do with an acoustic piano touch action
@@verymozart I haven't tried that one yet but I been wanting to. I own the Studiologic Numa GT and is the closest to an acoustic piano.
I'm not sure Kaiwai would appreciate you calling the RHC Semi-Weighted. That is certainly not what they advertise.
Thanks for your comment. I used the phrase "semi-weighted" to highlight that the weighting of the RHC is different than that of the RHIII. Eric (the commenter above) offered a similar suggestion, and I appreciate the feedback.
I read that the hammer action of the keys of KAWAI KDP 120 is just basic. So not the best for advanced pianists. Is that true? Are the key too softly weighted for advanced classical music piano practice??
I agree that the KDP120 action is more basic--it uses Kawai's Responsive Hammer Compact II Action (which is a predecessor to Kawai's most current plastic key action, the Responsive Hammer III). If you're looking for a higher quality action, I would recommend the CA49 since it is still at somewhat of a mid-range price point and uses longer wooden keysticks.
@@BayAreaPianoMasters CA 49, you think is fine for advanced practice? But it's expensive for my budget, even because you have to include the costs of the stool, the headphone and to install it it costs as far as £ 250.
I saw now there's a bit cheaper Kawai CN39, that states has hammer action III, but l don't know. Or maybe Kawai CN29? I'm a bit discouraged honestly, because it seems l won't find a digital piano for my needs within my budget 😔. Thanks for your reply
@@verymozart The piano bench comes in the bundle with the CA49, but, yes, headphones would be an additional cost. In the U.S., the CA49 retails for $2299 USD and the CN29 retails for $1959 USD. (I have a CA49 at home, and I completed the assembly with 1 other person on our own. It's a little time-consuming, but it can be done :) ).
The CN29 and CN39 use the same action--the 39 has upgrades to the speakers, sound selection, and the Bluetooth connection.
I'm not sure what your budget is, but purchasing a portable piano will typically bring down the cost of the piano. The Kawai ES920 uses the same action as the CN29 and 39, but it costs $1599 USD. It doesn't come with a stand and bench, though.
Even though the KDP120 has a more basic action, it still is better than the action of the ES110 (which uses Kawai's most basic action, the Responsive Hammer Compact).
Hope this helps!
@@BayAreaPianoMastersthanks for replying. I think KDP 120 is too entry level and the Hammer action too basic for advanced practice. O can't afford CA 49. All l'm trying to find out now is if the CN39 (with Hammer Action III, full weighted keys, and high polyphony 255,) is appropriate for advanced classical music piano practice. That would be within my budget. I found a dealer here in the UK with a nice price, included: bench headphone, 5 yrs guarantee, (plus £180 to assemble/install it, l live alone and can't assemble the top without someone else). And in 3 interests free payments.
Grazie!

i have a ypd 144 anyone know which action from kawai may be similar to the one used in my piano?
Very nice, As an Acoustic Piano Tech I'm having a hard time finding anything on the older Kawai CP series actions with some of the first wooden keys. I need to find the plastic parts that the counter weights pivot in For a CP-150 . As well as the pads if still available. Besides the broken part some of the notes sound louder then others, I think that is the pads or just dirty. Any help pointing me in the right direction would be appreciated.
In regards to the some notes sounding louder than others, it sounds like there is an issue with some of the sensors. I am not sure where you're located but you may try contacting the parts department at Kawai directly for the parts you are in need of. You can ask for David Reed and see if he can assist you. Kawai's number is listed on their website.

ES120?
The ES120 uses the RHC action!
anyone knows how the rhc2 compares to the rhc3
How long are the keys on the GF2
Approximately 13 11/16 inches. We'll be doing a video comparing the GF2 and the GF3 soon :)
San Mateo Piano: Thank’s for this. How did you get this information? Did you remove the top of the piano. I used calipers on supposed scale drawing in a brochure. By so doing, I “calculated” 16.9 inch keys. They do fit the sanity check. I’m very curious.
On a total other key length subject: I measured the keys on the KAWAI GL series grands. The key length on the 5’2” baby grand are 20”. The key length on the SS Model “M” is 19” and on the BOSTON’s is 18.9”. (Ken length contributes to the ability of playing pp and ppp passages more responsively. (BTW, 19” is a VERY adequate length.) Long is good - but has to be merged with a good action, of course.
@@kenpeters9807 I would definitely need a technician's help to remove the top of the piano! I measured the GF2 action model that we were sent by Kawai.

whats absolutely hilarious about this is how no one can replicate old technology using new technology. Yes, things are always improving
It's all about what do you want it for. There are keyboards designed to be light to touch but have the fastest "reset" moving up so you can play it repeatedly easier, great for electronic music and organ playing, awful feeling for classical players.
Newer tech made cheaper actions feel closer and closer to real acoustic pianos.
To the extreme of some hybrid pianos having the same keyboard mechanisms as a concert grand, but using sensors instead of strings. Not cheap tech, but really advanced!
🤓🤓🤓🤓
What's funny in that? 😅 I guess you're too unaware about tech today. Have you seen novus 5 and 10?
You can bring your old technology easily around??? And play with headphones at night without costing a bomb? You are the hilarious one
The difference between a longer key and shorter is so minimal it’s not worth to pay $3000 extra so i😊
