- MINIDEXED is a superb implementation of 8 instances of DEXED, the free DX7 emulator, on a "bare metal" Raspberry PI. Think of a TX816 in mini format. In this video, I walk through the installation, setup and navigating the menu. Table of contents:
00:00 introduction
01:00 assembling the PI setup (LCD and rotary encoder)
01:32 other hardware needed
02:45 installing and configuring the software
03:30 navigating the menu, setting up a performance
06:34 important considerations
06:54 demo (synthwave... )
09:36 bye-bye

On the video you show creating the sysex/voice directory.
How do you access these files from the hardware please. Got me scratching my head.
Currently waiting on a screen and rotary.
@@elusivemite those show up in the "bank" menu. MIDI program changes and bank selects should work.
@@elusivemite please plug in a screen (hdmi) while booting. do you spot any error messages like "invalid filename"? if yes, just rename your SYX files to something like 01.syx, 02.syx and so on.
@@mr_floydst il give that a try later thanks. Don't recall any errors but il check in a bit.
@@mr_floydst that did the trick. As an aside. I numbered the banks and put names in brackets after the digits and it loads them fine .
I have delayed building this project until I could get my hands on another Pi4 (the only pc format that I fully utilise) but building a MiniDexed has by far been the most rewarding and useful tool I have built in recent years. As a rather poor pianist and keyboard player this has put the iconic sounds of about three decades of popular music into my hands in their fullest glory. The sound quality with the external A/D is superb. Thanks Floyd for bringing this little project to the populous through your channel.
Thank you very much. I agree, this project strikes just the right balance of usefulness and amount of work needed.
Thanks for the Video, great content and great sound! really showed that off using those Stereo sounds, great work! Would be even greater if it was possible to combine f.e. one core of BareMetal and a single-core Linux installation which could handle a Web-UI. That would make this project so much easier both to build and to handle. Is that even possible? F.e. 1 Core BareMetal+SingleCoreLinux for Pi2-Zero which I have laying around. Another version would be a Pi-PicoW or a ESP32 to handle the web and a BareMetal PiZero-2 for Sound generation.
Hi, thanks for watching! At the moment, I think this is not possible. Projects that are built like this commonly use an Arduino or Teensy on top of the PI for additional user interfaces / inputs.
They should add support for an opsix-style mixer section: six faders for operator level and six pots for operator ratio. Edit: CC support is on the project’s to-do list!
Yes, it is! And I can't wait for it. :-) This is without doubt my favourite open source project in '22 so far.
CC support would be essential for me for playing it from my Roland AE-30 wind synth.
@@unclemick-synths I believe DX7 patches can already be setup with aftertouch or breath control, so you should be able to use a wind synth! maybe try it out on dexed, free dx7 vst
@@maxspencerkarinen6463 thanks Max. I dug out the manual for my TX7 and it's in the function memory rather than the voice memory so I'll have a play with that. Not as convenient as my DX27 (breath is built into the patch itself) but if it works I'll be happy! It won't be using all the features I can send it but better than nothing.
Thanks Floyd. Another great video with a lovely chilled out Sunday jam to boot.
Thank you!
Thank you for sharing this project, would love to see more!!
Glad you liked it. I will definitely do a video trying to create a patch using only the encoder, and I will do another one once the MIDI controller support is there.
The future is now. Especially if you want to relive the past! Awesome project. Nice work, sir.
Thanks, Scott!
Beautiful !! That Is really Amazing ! Load time quicksilver ... Great Aldo the possibility to load soundfonts
Wow thats so cool! Im definitely gonna build that! The tx816 is a bucketlist synth for me
I thought this was the coolest open source project II've seen this year, too :)
I just got a beautiful DX5 and I almost got a tx816 when I was shopping. I fell for the DX5 what can I say, it wasnt rational. :) This is SO cool though, I think it would be fun to build a chassis + touch UI for it!
@@mr_floydst ive just built a Headless M8 and I love it!! I am working on that midi out mod, I dont see why the midi in couldn't work, so Ill try that one too
JUST INCREDIBLE SIR!!!! THANK YOU SO MUCH FOR SHARING!!!! everything so easy for us to follow. You are a very good man!
Thank you ;-) Glad it was helpful.
Wow this looks really awesome. Looks like it could be used as a standalone hardware FM synth (which is something I don't have and but want to have) if one gets a proper case. I think I'm gonna build this in the summer holidays :).Thanks for showing us this. And also nice jam.
Thank you very much, Jon! :)
I’m amazed by the new technology and your ingenuity,Sir 😮
I still have a DX7s, bought it brand new with huge some of money and mine turned out to be somewhat temperamental few years on. I’m so glad that software emulation is here nowadays and Dexed brought Dx7 synths back to life 😊.
This video gives me a reason to research Raspberry pi’s and other associated projects. Well done 👍 Big thank you
Thanks for watching and for your kind words! I just wanted to make it clear that the actual software was developed by @probonopd and I'm merely the messenger. ;-)
I have a playlist on Raspberry PI synths on my channel page, th-cam.com/video/ae5TYhnhp3w/w-d-xo.html, which might serve as a quick overview on what to research next.
I was amazed by this project. I'll build one! Thanks for sharing.
Thanks for watching! :)
Hey Floyd, your videos and music just keep getting better!
I’ve been looking at the SY70 or SY100 for awhile now, I think I might go for it.
I’m surprised there doesn’t seem to be any modern product that has the functionality of that thing at a decent price, in theory it seems like a great machine to sequence multiple hardware synths with.
You mean the QY100? It absolutely is, and you're right, there's nothing like it at the moment.
@gridsleep the SY77 is a synth I'd like to try one day.
Still got my qy70 , I will never sell it
Great work, and nice music too.
Keep it going.
Thanks for watching! Will do. :-)
This looks so good. I'll have to add it to my list of projects to make whenever it's possible to buy a Raspberry Pi again :-(
Thanks for watching! I didn't know it's hard to get one at the moment. Chip crisis?
@@mr_floydst Pi 3 is selling for $200 bucks, a Pi Zero will run you $95, aside from that this would be great release timing giving the announcement of volca fm2
thank you for the video and the song!
Amazing, I love the DX7 !!
Thanks for watching! :)
amazing thank you so much. You've helped my project a lot
Thanks for watching! Glad it was helpful.
That was pretty cool. Actually making decent music from it was the highlight.
Thanks!
Holy CRAP this is awesome!
Thanks, Clemens! It is, isn't it? ;-)
Thanks for sharing. Had a pi4 on the mantlepiece doing nothing so had a test earlier. Il definitely be building this up.
I'm hoping I can push midi din through my sl MK2 into dexed to intergrate this into my setup
There are so many PIs sleeping in some cupboard or resting an mantlepieces in this world. Let's give them a new lease. :-)
A QY-70 sized case with lots of buttons and knobs for this hardware would be dope!
Yes indeed. :)
What a great project! I get one or two pi4’s, already have ordered two types of audio modules (one with PCM5102A and one holding a PCM5122), I have some rotary encoders and a 16x2 LCD, but I plan to use the 128x64 I2C OLED instead.
The end goal is to make a euro rack module out of it to fit my diy synthesizer.
Thanks, and good fortune with that project. :-)
Looks really promising, but it would need cc support to be of any real use to me as a wind controller player, hell if it did midi and audio over bluetooth aswell, I might even make it my primary synth! Looking forward to watching this grow
Thanks for watching! CC support seems to be on the feature list next.
@@mr_floydst cant wait to try it,I've always loved dx7s and having dedicated hardware for it and dexed in the daw for editing would be awesome
Nice! Even better than the Volca FM2 :)
Thank you! - I don't know, maaayyyybeee? ;-) Polyphony and multitimbrality is bigger, obviously. :-)
You ARE Dx 7 Floyd. It is you. Dexed, minidexed, dx7 all of it, its you.
Towards the End i saw the Fifty Shades of Floyd :) it was Floyd from different sides, zoomed in. zoomed out... flipped...yeah well Floydification in editing :)
Narrrrrgh you! :-)
Good video 👍. Very interesting for me if it could also have 5-pin MIDI to use completely standalone and also to be a patch librarian for my TX7.
You can use a USB to 5 pin midi converter for around $10. I used one in this video.
Been testing today. Installed on a pi4.
Usb midi into the pi from a novation SL mk2. (built in midi interface.) Midi din from my rig into the SL and to dexed. Able to play (and later program) from my SL and sequence it at the same time via din from my MPCs
I wonder if anyone with experience with the Korg Volca FM might compare the two. Very cool project.
This is wonderful, thank you for sharing! Instant sub, cant wait to dive into the rest.
Now I really want to build a Minidexed unit myself. I'm not bad with a soldering iron, but a complete beginner in terms of how stuff actually buttons up and how to follow the quite daunting schematic on the github.
If you happen to have any advice, I would be most grateful. A vague request I know!
You can buy a breadboard and a couple of wires from Aliexpress, bypassing the soldering.

@@mr_floydst wonderful, thank you very much for the reply and information. Keep on keeping on making cool things!
I'm defo gonna build one of these. But not a fan of the minimalist interface (though it does make it VERY compact and portable). Gonna slap on an interface like I did for my HS Expander I think, since that is still pretty minimal (3 sliders and an LCD) but removes all menu diving :)
Amazing what fits on an tiny board like the RPI these days.
Thanks for watching! - yes, an external MIDI controller certainly helps here.
Floyd...you keep making my to-do list of projects longer and longer. Still need to try the teensy m8 build and your webmidi sequencer. Oh yeah, need to try out the full blokas labs pisound build of modep with a guitar to see if it sounds any better than when you compared it to Zoom MS-100bt.
Thank you, Ted. I think today's "project" is done really quickly, as all you need to do is unzip that synth onto an SD card - it will turn your barebones PI into a DX7 no questions asked. All you need to do is to connect a MIDI controller that can send program change messages. By default, sound will come out of the 3.5mm jack. The LCD and other stuff I showed here is entirely optional.
Great walk through. I must try to build this myself. Your QY70 looks like it has a backlit display - is this just an artefact of your lighting setup or have you added a backlight to your QY70??
Thank you! That's just the reflection of my studio lights, unfortunately. Would love to have a backlit LCD on this.
Interesting concept. The big problem with 80's synthesizers on the raspberry pi is they're all VST plugins for windows & the windows PC is way across the room.
But does your Windows PC boot within 5 seconds? :)
Yer such a Tinkerer eh lol well done, bit of a mess but results speak for themselves .... Thank You
Thanks for watching! Yeah, using a breadboard always looks a bit shoddy. Advantage is you can reuse the parts later.
hi Floyd.
Great video- thank you!
What's the latency setting on this? How low can you take it before crackling?
Hello, thanks for watching! I didn't measure it, but due to the fact this project just skips the operating system altogether, my impression was there's no latency to speak of. Just try it yourself, it's installed within seconds, it's just a matter of copying those files to an SD card.
2030: we can now run 8 Roland JP-8000s on a Raspberry Pi 7... haha in my dreams!
Hi, thanks for watching! Perhaps I'm overly optimistic here, I if a software emulation of the JP8000 existed, I'm sure the PI4 could run 8 of them.
You could try ZynAddSubFX, it has the supersaw wave, if I remember correctly. ;-)
@@mr_floydst The JP8000 came out about 15 years after the DX7. The DX7 was 16 note polyphonic in 1983, JP8K only 8 note polyphonic in 1997. That gives some indication that the JP is much harder to emulate than the DX7.
Could you give us some details on the off-screen connections? Are you taking the nano keys to a usb to midi converter and then to the qy70? Is the 3.5mm output on the pi going to your pc?
Thanks for the great video
Thanks for watching! Ah, I always assume everyone watched my previous videos when in fact that's rather rare, haha. :-)
In the demo, the Nanokey is connected to a USB MIDI host built by Hobbytronics in UK, which sadly is out of production. MIDI out of that host goes into MIDI in of the QY70 (a pocketable battery powered 16 track sequencer which serves as a "MIDI mixer" here and that also plays back an 8 measure chord, bass and drum pattern)
MIDI out of the QY70 is connected to the MINIDexed, which is playing the pads, bass and EP.
All of this is recorded on a ZOOM R20 multitracker.
Would be glad to see this as ready-made tiny box. Maybe as one extension board, norns-style. Have you considered this possibility? I think this should be a hit, tiny multitimbral synth!
This project has so much potential as everyone has a RasPi somewhere in a drawer. And yes, if you own a 3D printer, you could easily turn this into a nice looking box. WIth the PI Zero-2, you could also tuck it into a MIDI hardware controller and create your own hardware synth. :-)
@@mr_floydst that's my plan. Though il keep the pi mounted behind the controller out of sight in a case and add the screen and encoder to the controller.
Super dope , I’m going to build this. I just got a dx 7 and totally restored it, I love it. Btw what is the purpose of that Yamaha thing there ?
Thank you very much! That's a QY70, a battery powered sequencer. I used it to play back an 8 bar pattern & drums in the jam at the end of the video.
@@mr_floydst is it polyphonic? I can look it up tho 😉 but keeping the conversation going is cool 2
Super cool video , ist the first one i see from you ! Thx
@@Solidsoundfx Haha, of course. But you can also watch my video on the QY100, which is the same thing but with an additional audio input: th-cam.com/video/2Sk2cSeHIN0/w-d-xo.html
To answer your question: Yes, it is. And it's got a super awesome feature dubbed "chord tracks" - you can create patterns as usual but you also specifiy the key they're in, and the QY series can than "hot swap" your pattern into another chord / key. I've never seen this on any other device and it was one of those "aha!" moments.
@@mr_floydst excellent !! Inwas looking for a good standalone smal polyphonic sequencer for my dx 7 and prophet 5 . But this thing can do so much more . Thx for the info anni will look at your video . Thx again
I sold a TX816 and miss it.
I need one of the new DX7.
Amazing thing!
Thanks for watching!
Minidexed works in headless mode, what an awesome synth! I'm surprised that the midi controls used for effects like reverb and cutoff appear to be hardcoded. Minisynth has a parameter mapping for this. My Alesis has a utility to change the values it sends, but I like to use my controller for several different projects, for example, I might have another SD card to run a different synth.
Hi, thanks for watching! You can always drop a feature request on the projects GitHub page. ;-)
If there was a way to have a more expressive synth that's suited to MIDI wind controllers (breath controller message)... Is there anything like Respiro or at least EVI-NER for Raspberry-like microcomputers?
Hi, thanks for watching! I do not know of such an app at the moment, though there are plenty of synths that can react to air pressure and expression. Some of those could create a relatively convincing "natural" sound if programmed carefully. E.g. ZYNADDSUBFX or Surge.
A version of this for the Munt MT-32 emulator would be a big score for DOS game nostalgists who want the full experience of the games that used that hardware to display text messages etc., without the high prices of the vintage hardware.
I'm not shure, but I think this exists. Got to google it...
That project is called "mt32-pi".
Why haven't subscribed for years?!
I saw that! Sneakily adding a QY70 to your collection without telling anyone! Any particular reason why you didn't use the QY100, or was it just because you could?
Hi! For the sake of this channel, I'm constantly buying and selling stuff, and after publishing the QY100 video, some viewers brought to my attention the QY70 is the same thing but without the audio input, and it's smaller. As I don't need the audio input, I sold the QY100 and found a QY70 for a very good price. Lucky me! :-)
Can you edit the synth parts with Dexed or use it for offline patch creation ? Not sure how that could ( if it does ) work with the multi-part architecture , But hope it does because a Yamaha TX synth with the equivalent of an alpha dial sounds like menu diving purgatory .
You can. In the DEXED VST, it's relatively easy, and here, it's possible, but maybe a bit slow as you have to click your way through a lot of sub-sub-submenus. But it's really easy to understand.
@@mr_floydst Awesome.
Now hopefully someone will make a similar project for OBXd . One of my favorite freewarez and probably the only way I’m going to have an oberheim type synth in hardware anytime soon .
this is amazing.. wold it work on a raspberry pi 2? or would I need to change some of the code..
It will work, but you will get only one "DX7" instead of 8.
@@mr_floydst Actually Pi 2 should do all 8. Pi 1 and Zero do only 1.

Im revisiting this project, but having issues understanding where to get the actual voices from. I think this video is great for whetting peoples appetite, but a tad too fast on the details of setting up and the intricacies. Is it time for an update video? ;)
Hi, thanks for watching! As this is built on DEXED, you can use any DX7 patch bank you like. It's in the video at ca. 2:40.
DX7 patches are all over the net: www.bing.com/search?q=dx7+patches
Edit: I might do another video, but in the past, a second video on the same topic always attracted little to no viewers, and these videos are a lot of work. So for my "mental health", talking about new things is better.
Will it accept a USB-cable with a micro-MIDI-interface? Something like a MIDI IN and MIDI OUT plug on one side and a USB-plug on the other side?
Hi, thanks for watching! Yes, that will work.
So you are running with just 1gb of RAM, that's impressive. Is there a benefit to use the RBPI4 with 8gb?
I didn't follow the latest updates, but I think there's no benefit in throwing more RAM at it. In fact, you can go even lower than 1GB because this skips the entire operating system by running directly on hardware.
I would like to try and build this on a Pi 4 with a Pisound.
I can't confirm it at the moment, but it should be possible. Please check for the chipset MINIDEXED calls for (I think it's on the Pisound)
can add more then one Potentiometer for control the Options etc ?
Thanks for watching! It's an open source project, so you could do it yourself. The PI as a lot of GPIO ports so you could add more without adding controller boards.
Is Mini dexed code equivalent to "Full" dexed ? Do they sound the same ? Btw those QY100 are so useful ! A band in a box. I wish Ive purchased one.
Hi, thanks for watching! Yes, it is. It's a full port and you can load original DX7 patches.
I agree on the QY series, it's so useful! And it has some astounding features I haven't seen anywhere else. I wish they made a new model.
@@mr_floydst Thanks, I will try it. Yes, Yamaha definetely has to do a new version of the QY100
I love this but I'm still struggling to get my head around it. Getting a midi controller to play all tracks but having seperate sounds/volume controls etc is not easy, not to mention changing performances/banks etc.
Hi, thanks for watching! I need to check the latest updates here, but I assume you're right. A more luxurious user interface would really help here.
any way to control things with OSC instead of a hardware knob?
Yes, that's possible. Please take a look at the project's homepage for more details!
I was wondering if anyone knows if there's support for midi CC control.
I have a m-audio keystation pro 88, and would like to build this in. And use the many sliders and pots to control parameters. I will this weekend when I get a chance, sit down and look through the documentation. But I was just curious.
Thanks.......
Hi, thanks for watching! Please look here: github.com/probonopd/MiniDexed/wiki/MIDI-Implementation
Thank you Floyd, that's great.
Hopefully I will have time this weekend to get something working.
Just a small question: When using a raspberry pi4b plus the Audio hat for this project, is there any knowledge about whet current this setup will draw from the 5 volt usb-c supply ?
Hi, thanks for watching! I'm sorry but I never checked in on that.
All I can say is you can run this project on a typical power bank for days.
I'll try to check power consumption some time, but perhaps other viewers can share their knowledge here?
Thank you for your prompt answers 😃👍🏻 Hope someone else can answer this? From the datasheet of the pi4 I know that the pi needs at least a 2.5 amps power supply but since your projects run from a bare metal pi, I guess the power consumption might be far less?
I have a preliminary setup and the power consumption is about 370mA @ 5 volt. th-cam.com/video/eVK8PfLgHwc/w-d-xo.html
There is need of resistors ?
Hi, thanks for watching! At the time of recording this video, no resistors were needed for building this. (This hasn't changed AFAIK)
Deer Floyd, do you think a Raspberry Pi 3 with 1mega will do?
Hello Wim, yes, of course. That's what I used in this video.
@@mr_floydst ah thanx!!👍😂
May i ask how is the latency (between playing a note and the sound coming out) of this?
I haven't measured it, but it's "practically nonexistent". There is no operating system and no audio subsystem, only the firmware interacting with the hardware.
i used DEXED on my iPhone thru my MC707, which can sequence the iPhone and return the audio, amazing. But i only get one channel of DX7, enuf for me...
i wish someone would make a better UI for DEXED app, it's not good.
Yes, that's right... The UI could use some improvements for sure.
could this be adapted to provide 8 separate outputs?
It's an open source project, so if there is a hardware that provides 8 audio outputs and that can be connected to the PI by GPIO or USB ports, the answer is "yes, theoretically". It really depends on what the developers will prioritize. There's a message forum in the Github page and I heard developers in general are really happy to get a donation for yet another cup of coffee! :-)
Is there a possibility to connect a digital audio output to this project. S/PDIF , Toslink ?
Hi, thanks for watching! I didn't test it myself, but please search for "I2S to Spdif TERADAK". That should be what you're looking for.
This would be even better if it utilized the official Raspberry Pi 7inch touchscreen instead of the rotary encoder and 16x2 LCD.
Thanks for watching! It's open source, so you theoretically could do that yourself. (Or join the discussion on github.com/probonopd/MiniDexed)
@@mr_floydst Thanks Floyd. I'm seriously considering this (even though I've just purchased the Korg Volca FM2 a few days ago) because I own two Raspberry Pi 3B+'s DAC's and official Raspberry Pi 7inch capacitive touch screens.
I bought the Pi's with the intention of porting my midi sequencer that I wrote for Mac OS to the Raspbery Pi but moving from Objective C to C++ and JUCE is very time consuming.
@@mr_floydst Hi Floyd, that github link didn't work for me.
I did manage to find probonopd via a search and in the discussions area, I found this answer, to someone asking about using another display.
"Graphical displays would be nice, but would also be a fairly significant piece of reworking of the UI everything currently assumes it is driving a "text" output supported by the circle environment."
I think it would be much easier if I just ran Dexed for linux LV on the Pi OS.
I'm a music newbie, but have an old RPI 1 lying around and a midi keyboard. One thing: can anyone recommend a set of .syx files I can download for this? I'm not really familiar with FM synthesis so don't want to create them all myself or try to gather together different patches. A solid starter set I can just download once and use is what I'm after.
I think a good place to start are the original DX7 patches: yamahablackboxes.com/collection/yamaha-dx7-synthesizer/patches/
Can you please provide more information on the PCB and wires etc. Already attached to the bread board? You sort of skipped over this in the video unfortunately
Hi! The link is in this videos description and in the pinned comment, but here it is once again: amzn.to/3TLG7O9
This is a beginners DIY set with some very well written tutorials. I can't recommend this enough.
Hello! Can we use HIFIBERRY DIGI+ instead of PCM 5122?

Can i play only one instance ?? Thx
Hi! Yes, of course. Any number from one to eight.
can it recieve sysex messages to tweek the sounds? ?

Great idea! Do you want to build this yourself or could you imagine recording some video snippets and send the MIDI data / patches used to me?
@@mr_floydst I may try to build one. Once I find some time! Never enough time!
Do you have this whole project, the "mini" TX816 ready to buy?
Where can I buy?

Hello, thanks for watching!
I'm afraid I can't do that. This is not a commercial project and _if_ someone would have the right so sell this, then the project's creator, @probonopd. You can reach him here: github.com/probonopd/MiniDexed
Dear Floyd, i did follow your instructions but i can't get the display or the dataencoder working. do you have any suggestion? i don't know what i am doing wrong. thank you for your comment.
Hi! The most obvious reason for that is "you've got the connections wrong". There may be five reasons for this:
1) you swapped some wires.
2) you connected wires to the wrong pins.
3) your didn't use exactly the components the project description calls for.
4) some of the parts you're using are damaged.
5) some of the connections you made are broken / cold.
I think it's rather unlikely this is a software problem. Start by trying your screen and encoder in other projects, verifying they're in a working order, and then try to rule out the other sources of problems. Good luck!
@@mr_floydst thanx for your answer. I tried the display on an arduino uno, that works. No I ask myself: do I have to upload a library for the dx7 project, or is that all in the software?
It's all in the software, no need for additional libraries. If you're stumped, please also check the projects homepage /github page, github.com/probonopd/MiniDexed
Also check your minidexed.ini settings.
Last but not least, you can always post your problem here: github.com/probonopd/MiniDexed/discussions
@@mr_floydst Dear Floyd, thanks for help! it works now. maybe i did wrong wiring with the display. the rotary encoder seemed broken (although it was new). so everything worked out well!
make this in series - I will buy one, How much could be ?
Hey, thanks for watching! Please understand I'm not the one who created this, I'm just reporting on it ;-)
Maybe @probonopd has intentions of making this a thing?
github.com/probonopd/MiniDexed
Gee, why didn't Yamaha do this for their little Reface thingies?
I guess the UI would have been a challenge ;)
The Reface DX isn't as bad as it's credited for with it's four feedback operators (the DX7 has only one of those, so you end up using more operators for the same thing the RDX can do with one operator).
@@mr_floydst I wasn't referring to the Reface DX per se, but something similar to it that would bring the DX7/TX816 experience in a little package.
I actually think the Reface DX is the best-sounding 4-op FM synth Yamaha ever made. But that's mainly because of the filters and effects.
does anyone have expierence building a 5 pin midi input for this project? Thanx in advance! greetings form the netherlands
Do I have to change something in the code to use classic 5-pin midi?
@@wimlenthevan5908 the doc mentions that the easiest thing to do is to buy one of those 5-pin to usb adapter cables and plug that into the pi! Easy peasy!
It kind of shows you how inexpensive a digital synth can be.
Thanks for watching - yes it does. Though analog circuitry quite the same. We mostly pay for R&D,, and in this case, the developers are kind enough to work mostly without being paid.
Shrank!
Ah, yes, of course! Thank you.
Edit: Well, no, I wanted to refer the 80s movie with the title, and it's _shrunk_ .
en.wikipedia.org/wiki/Honey,_I_Shrunk_the_Kids
@@mr_floydst Still wrong though. :-)
Now it just needs a knobby interface and people will have the DX7 they always wanted.
I think this will happen more sooner than later - project is quite active.
Great video. Thanks for doing this. I got minidexed running on my RPi4 without the display or knob or soundcard. Using the M-Audio Oxygen49, I can at least change patches on it. It's like a cheaper version of the Korg Volca FM, but with more polyphony (it is at least a 5 note polyphony, but it might be higher). Looking forward to slapping a hifiberry audio hat into the unit to clean up the output.
Thanks for watching! On a PI4, you should get 8 virtual DX7s, which means 8 part multitimbrality and 16 voice polyphony each (8*16= 128 notes)
@@mr_floydst Thanks for the info. I've been noodling this this gadget off and on this afternoon. It's a little tricky to manage without the display, but I can see the possibilities. And I've never had my RPi boot so fast. :-D
great great... cant await to see this in some studios...
Thanks for watching! This project is off to a good start, and it's worth keeping an eye on. It might be studio ready sooner than we think. :)
@@mr_floydst oh yes a friend, i think he has contacted you already is planing to do a small run of modules :-) great one. i love FM and have a lot of old FM Synths :-) Thanks for doing this.... stay helath and take care.
Looking to make this a bit simpler. Does anyone know how to modify the ini file permitting support (as Zynthian does) for the behringer UCA series of USB audio interfaces? Also the
DFRobot IIC 16x2 RGB LCD KeyPad HAT for Raspberry Pi V1.0, has controls on board and appears to be a vastly more convenient solution, as it's a hat... does this work/anyone know how to make it work if it doesn't .
In essence, trying to get all of this running on a PI3, using an M-Audio 1x1 midi interface (which should just work), that LCD and the behringer for audio (as it also has optical Toslink output, which will mean I can very cleanly stream to my mixing desk)
Many thanks
Hi, thanks for watching! As long as your audio converter is built around a PCM5102A or PCM5122 chip, it should work. Regarding MIDI setup, please join the discussion on github.com/probonopd/MiniDexed/discussions .
Voila ! Mr. Einstein.
well, uhm, no. :-)
What a cool project! I mean, sure I can do all this on my computer but still, it's pretty mind-blowing to me that all that horsepower required back in the good ol days is now just a small pile of inexpensive stuff that fits in the palm of your hand!
Thank you! Indeed, this is a cool project. Yes, of course a PC can run anything, but here's potential to create you own hardware controller on top of it (if you like building things).
Great video! Is there a wiring diagram out there somewhere? I have everything ready to go but don’t know what wires go where.
Thanks for watching! The wiring diagram is on the same page you can download the software from. I talk about it in the beginning of this video.
I guess I meant header positions. I look at the wiring diagram and I am completely lost. Thanks for replying to me so fast.
How many banks (voices) can we add on sd card?
Thanks for watching! I have not tried this myself yet, so I can't really answer your question.
Theoretically, there's nearly unlimited space for patches, but I'd make an educated guess there might be a limit of 128, 256 ... (x to the power of 2) files. ;-)
you killed it with this video floyd one of your best :)
Thank you very much!
After I see this video I assembled the circuitry and put minidexed on a 2GB (!) SD card I had knocking around. Sadly my LCD has died since my last project, so I'll have to get a new one, but it sounds absolutely wonderful. It didn't like my AKAI MPK Mini Play (I think because it doesn't default to midi mode ?) so I had my Beatstep running patterns through it. Even the analogue audio on the Pi 3 sounds good though!
Anyway - thanks for another excellent video!
Thanks for watching! This project is worth keeping an eye on for sure.

Thanks for watching. Yep, this video was quite the success for me.
I made one, and this works! Thanx, Floyd !
You're welcome!
With more of these pi based solutions coming out, it would be nice to see an enclosure available with the capabilities to support them. Im talking a shield with inputs/outputs/audio dac, screen, controls.
That would be nice, but I think it's unlikely to happen soon. Developers would have to settle for a standard (interface assignment) and there's R&D and marketing and distribution costs involved - a lot of work and risk to be taken. Could be a kickstarter project perhaps.
@@mr_floydst Besides, DACs are unobtanium. Look at stock on digikey and mouser, it's all zero stock with 6 months or more wait time. It's great we can find these boards in stock now, but good luck if you want to start making new stock and you're not already on someone's priority list.
You had me at “bare metal”
Thanks for watching! :)
Great video. I'm excited to try this out. Also, Raspberry Pi prices are crazy high currently.
Thank you! Yes, some viewers already mentioned the current prices. Hope that will go back to normal soon...
Looks, sounds super rad. Nice work!
Thanks a ton!
Amazing, simply amazing sound. But hey, I can't believe how well you play the key2, I couldnt even play on regular Keys. The drums are from the yamaha? Or are you using it as a sequencer? It's amazing
Thank you very much! The drums are indeed from the sequencer I used, not from the MiniDexed.
hello, great project! can you edit all parameters via midi?
Hi, thanks for watching! Not yet. It's on the developer's to-do list next - please take a look at their GitHub page I linked in the video's description.
Tempting, but I would hate to be stuck with one control and a two-line screen for editing. Might the devs later implement a capability for a touchscreen and multiple encoders?
Hello, thanks for watching! They're working on MIDI CC support at the moment according to their github page (please visit that to join the discussion).
There's also MicroDexed, a similar project for the Teensy microcomputer: github.com/dcoredump/MicroDexed
They're working on what you are asking for, but due to the lesser CPU on that board, you will get 2 "DX7s" max.
Woow this is nice!! How many voices does it have pear sound module? Really looking forward to make this project
Hi, thanks for watching! You get a full DX7 per module (16 voices).
Thank you very much for making and posting this great video .....
This is is just great for an old Raspbianic diving into Musik! 🏁
Thank you too! :)
