    Hi UHF,
    The PCB and front panel look great. You do fantastic work. Where did you make this in?

    Hello, I'm using KiCAD. I'm trying to get a decent looking front panel silkscreen and am also playing about with Eagle on Fusion 360. The front panel will be red with white graphics, although JLC offer other colours including matt black. The components are chosen so that you can get them from a 'proper' supplier (like Mouser, RS, DigiKey...) or go to AliExpress and save, because most of them are fairly standard. The 4067 MUXs and MIDI optocoupler components will be SMDs that JLC will assemble onto the main PCB. They'll probably be offered on Tindie or whatever, I need to actually make one first though! I also need to do another demo video, as I want people to appreciate the range of sounds that it's capable of.

    Hi UHF,
    I just came across a board that is not available yet named DAISY. It is on Kickstarter. Maybe it is worth checking out, always good to know what others are doing. https://www.kickstarter.com/projects...form-for-music

    A monosynth for $399 hmmm... or a programmable poly for $99.

    Hi, do you plan to release the schematics for this impressive project

    Hello, thanks for all the interest. This will probably be a last update. Further information for those interested will be here electrotechnique.cc. The PCBs arrived last week and I'm pleased with the results. The prototype is shown below and is fully working with updated code. I'm anticipating that it will be ready by May and the website will be updated with all the files, including plans for an enclosure. It is open source with the exception of the files to create the PCBs. I'm hoping users will contribute to the code. A Teensy 4 version will be available when it's in a larger form factor, supporting the same functionality.

    Very cool. Why didn't I see this thread before!

    I very recently built the Notes & Volts TSynth and while is was pretty good, I was also disappointed by the anti-aliasing of the saw and square waves. Could you explain how you solved that problem, or am I using an old version of something?
