You seem to look down on spring-loaded keyboards but spring-loaded / synth action keyboards are much preferred by many (including trained pianists) for playing synths.
I saw that too. He seems to look down on synth action keys. Professional keyboardists play keyboards with synth action all the time. It is not ideal for piano playing but excellent for synth sounds, strings, organs, brass sounds, guitars,...
A keyboard instrument is not necessarily a piano (obviously), so a keyboard action optimized for piano playing is not necessarily the best for other instruments. A piano key is the result of several processes, one of them is the physical need to generate sound hitting a string with a "hammer" in a mechanical way. It puts a lot of constraints about how a key action can be. In particular it needs some effort to make a reasonable amount of sound, even more in lower octaves where springs are thicker and heavier. So, the strength needed to play a key and the gradual increasing in lower octaves are a physical requirement, not necessarily a virtue. Arguably, one could get more agile playing with lighter touch, specially in left hand octaves. Moreover, if you need stronger force to play a note probably you are kess capable of light nuances regulating that force. However, piano teachers and classically trained players are "trained" with the traditional piano feel so they feel strange and "bad" any other feel. It is like us with a qwerty keyboard, there are better designed keyboards but we have learned with qwerty and any other configuration tends to result very cumbersome to us. In short, not everyone and not every instrument has the "piano feel" as optimal. IMO it's wrong to identify "piano feel" as better and "not piano feel" as worse and "cheap".
Keep the things simple and true. If you want to play anything (not only classical music )on a piano then you shouldn't take light keys. It will give you a bad technique. That's not only a feel as you wont have the required amount of strenght in the fingers you would need on acoustics . If you want to play the keyboard then all choices are valuable depending on what you want.
I watched another video you made. My mom is a piano teacher and fully weighted is necessary. One of our cousins studied under Mme. Long, in Paris and she had 3 pianos in her apartment: 1 for teaching, and Yamaha wall piano and a 1/4 grand piano. The Yamaha, she asked a technician to make the keys even heavier and she used it for practice while the 1/4th was also tweaked to reduce the key travel. Fully weighted hammer action is necessary if a student wants to learn Piano. Oh ... my mom tells me the best option is a real Piano.
I learnt playing on a Yamaha digital piano purchased about 10 years ago and did not have any weighted keys. On a recent trip to a music store I was shocked how I couldn’t play any of the keyboards due to all of them being weighted keys. I don’t have any aspirations of playing an acoustic piano but the issue is I’m not able to find any keyboards that don’t included weighted keys anymore if I wish to find a newer upgrade to my old Yamaha
I've disassembled my P-95 a couple of times. Its keyboard action looked really funny to me the first time I saw it. The key mechanism is like any other keyboard. In fact, it's just like a non-mechanical computer keyboard. The thing is each key is connected to a huge metal hook that does nothing to produce the sound, but is the sole responsible for the feel. It's simple, rather primitive -- it's an old entry level digital piano --, but fascinating nonetheless.
I've seen like 5 different videos and like 10 pages, and NO ONE can give a consistent explanation, some confuse semi-weighted with Weighted with Synth Action. Also, the marketing is messing with the terminology. Nowadays ALL say Semi-weighted, no one says Synth Action anymore, despite of beign just a spring loaded, and even worst, some of them doesn't even have springs, is just a plastic bridge that tends to break rendering the key unusable
Roland wasn't mentioned. And in the middle I really didn't get what makes a keyboard which type of... Must be part of the marketing. As a technical guy I'd say they have springs or hammers. Hammer ones have different versions of reaching the acoustic piano feel vs. certain price point. Roland PHA-4 has two moving parts: the key and the hammer, but it's awesome for the price (starting from FP-10) and otherwise too. It's just on the heavy side, the acoustic pianos I've played are lighter to play.
Fully weighted - $100-$300 Hammer action - $350-$500 Graded hammer action - $550-$800 Graded hammer action with escapement - $850-$1500 The most expensive hammer actions are graded key by key with a realistic ibony/ebony feel, double escapement, triple sensors over 350 notes of polyphony, high quality piano samples and 40 watt speakers. Just all that without any other bells or whistles can be up to $10,000. Just buy a damn acoustic piano.
There’s a reason why there is a whole market for digital pianos sure acoustic will always sound great but most people just don’t have the room or money to retune an acoustic both have its ups and downs
My 61 key Roland D-5 is "synth-action" . Synth action will allow you to do more with a board that you are using for Midi-composing as you are using the board to simulate many different instruments. There is a real need and interest with many composers to find an 88key "synth-action" keyboard, but alas, I can only find Synth-action in 61key and below. Its very disappointing. : (
Hello, can you please explain why you prefer it. I'm about to buy one because it sounds good within my budget but everyone keeps recommending weighted which is way too expensive. By the way I'm only starting to learn.
@@crochetlover1880 if you’re starting to learn and you’ll take lessons, you should probably go for a fully weighted keys piano. Personally, I prefer semi-weighted keys ‘cause of the weight of the keyboard and his versatility (you can play easily pianos, Ep, organs and synths)
You glossed over semi weighted really quickly, then said you don't want it, but you didn't say why. And your explanation of it being in high end organs only doesn't seem to match up with what I've seen available.
is Roland's FP-30X and FP-90X with PHA-4 and PHA-50 action like a hybrid action? What about Korg's D1 RH3? I think probably the best you can buy is Kawai's VPC1, and then Kawai MP11SE and Yamaha CLP785... and then it is either Roland's PHA-50, PHA-4, and Korg's RH3.
Roland PHA-4 is really good! I have FP-10. For that price the keyboard and sound is amazing. It has the same sounds (just not all selectable from the panel, need phone app via BT or MIDI) and action as FP-30, FP-30X. I needed a good keyboard for gigs and Roland was the choice because of the sound: I had already used 1989 Roland digital piano. My music is synthpop mainly. What I miss in studio or live is the local off feature. FP-10 doesn't have it. I can't use it for controlling other synths while having its own sounds played by sequencer, or split.
Is PHA-4 hybrid or what? This video left me pretty much out with this. I've just got my FP-10 open and I can see it only has two moving parts: the key and the hammer. Of course the switches/sensors at the back too, but for the action you don't feel them. Weights: PHA-4 has four zones with different hammer weights. Maybe the "4" comes from it.
Please tell me about the new 2024 Donner DDP 80 Pro! It says “hammer action weighted” but it does not say “graded, progressive, or hybrid.” I can’t get anyone from customer service to respond to me. Is the Donner DDP 80 pro a good digital keyboard to buy for pianists looking for a product to be as similar to an acoustic piano as possible? All the sales terminology is confusing! Thanks 😊
hi thx I still have my original Rd 700 that I connected to my pc with pianoteq 8 very good i adjusted the hammer sound and like it a bit old a bit out of tune this you can't do with samples and I really feel as if i am playing a real piano .i had some in my youth
This video is biased towards piano players. I'm that case, hammer or weighted hammer action is preferable. But there are expensive professional keyboards with with synth action that professionals use all the time for playing synth sounds, strings, organs, brass sounds, guitars.
The plastic golf club example That’s EXACTLY my mother I only have this really shitty spring Keyboard (better than nothing tho) And it also sounds shitty so you can’t really play a lot of songs on it and it only has 36 keys… And whenever I ask her if I can get a better one and that I would even pay a bit of it, she’s like: ,,Well you don’t line playing on this keyboard. So from where do I know that you’ll like to play on other keyboards?“ It’s honestly just annoying Like I even play on the pianos/keyboards at friends and families houses and she knows that
On the extreme low end, I think you can add the "computer keyboard membrane switch." One example is the "Carry On Foldable 88 key keyboard" with a suggested list price of $100. Spring action, but the switch part may be different than other low end keyboards.
I bought a p-125 because i thought it had hammer action and just realized i got scammed. thanks. It's still decent as i'm not even a year into learning piano so i'll think about upgrading into a more high-end digital or even an acoustic piano later on
No no no, although the guy in the video is correct. He says it too vaguely, the p-125 IS a graded hammer action keyboard. its CLOSER TO weighted keys rather than a traditional acoustic, but it is not the same at all! You're basically getting the "feel" on the cheap. but considering the p-125 is what.. 699? that's about what you'd expect. however transitioning from a hammer action keybed to the more expensive ones like say, the kawai grand feel keybeds or the Grandtouch keybeds from yamaha or even acoustic pianos wont be difficult, you'll just feel a bit more in control - and even that comes down to taste! You don't need to worry about your purchase, for a learning piano its a great choice. Do upgrade if you play a lot and are passionate about playing piano though! Fyi, I worked in a music store for some time.
@@jokmong2360 Presumably you mean the successor FP30X as i dont recall them producing the previous model anymore, but the keybed wasnt changed regardless, I just wanted to make it clear. - Both keybeds are great in my opinion! The kawai is a tad more "responsive" as it bounces back more easily, it also doesnt have escapement if i remember correctly which can be a bonus depending on if you like that or not. It's a fairly lightly weighted keybed, but does feel good under your fingers when playing for long periods! For comparison its lighter than most hammer actions, but not quite as light as a semi-weighted keybed. (Of course, it being a hammer action keybed its a very different feel overall from the more simple weighted/semi-weighted ones.) The FP30X "feels" more authentic due to its weight and ivory touch keys. But they can feel a little mushy at times, as they bounce back a bit slower compared to the kawai. I will say though, if you have untrained fingers for piano playing yet have no plans or reason to believe you'll ever play an acoustic (which naturally has a bit of weight to them), i'd probably go for the kawai simply because it will be a lost less fatiguing to play, unless of course you wish for that extra weight regardless! Like I said, they are both great keybeds.
As a pianist for 20 years and music salesman, I will tell you that the p-125 is probably one of the best bangs for your buck and you shouldn’t feel like you’ve gotten ripped off.
A hybrid piano is basically an acoustic piano, but it produces it's sound digitally. (so no strings) // It's a digital piano that plays like an acoustic. It's all hammer action though, they just come in different grades and price points. lower end hammer action keybeds will have less sensors and accuracy(specifically for detecting repetitive playing), as well as the weight of the keys will be graded in sections rather than per-key. Also most lower end will need more force the higher you play on a key compared to at the end of a key. I recommend the video "Kawai Digital Piano Action Comparison" by san mateo piano for a more side-by-side comparison and explanation of these different types.
@@WorshipLifemusic Basically the cheaper version of the RHC keybeds. (The Responsive Hammer Compact to be exact) The one shown is the non-compact, Responsive Hammer III. which have more weight and feel a lot closer to say, an upright piano or smaller grands.
Bogus, unless you’re into piano *only* playing. Synth and semi-weighted action is desirable for certain players and styles - not only for weight and convenience.
Lots and lots of talk and it's still not clear to a newbie what is going on, is "fully weighted" same as "graded"? This is clearly MUCH simpler than it's made out to be on this video, and should require much less than 15min to clarify.
Nice that you discussed the different key action in piano...I just wished that all your piano review also tackle what kind of action the keyboard has and/or how stiff the key is rather then wasting time on tone or different timbre a piano has!!!
