    [queued] Teensy polyphonic FM synth

    Hi,

    I recently started working on making my own synth because I canít afford to buy one but I have already a Teensy 3.2 with its Audio Board.

    So I made a simple polyphonic FM synth, that is also standalone, meaning I can connect my Launchpad to it to play notes without a computer in between.

    The setup is really simple, I just have a USB Host chip connected to the Teensy, and then I can plug the Launchpad or any Midi instrument to it via USB.

    Here is a demo:

    For now I donít have any potentiometer connected to it to adjust parameters while playing so the envelope and the modulator frequency are fixed but Iím planning on doing that.

    I open sourced it on my GitHub. Itís at a very early stage but you can already use it or even contribute:

    Let me know your thoughts!

    I very much like your approach for patching a polyphonic synth without too much effort. It makes complex synth designs a lot more manageable.
    Thanks for posting your code.

    I just added potentiometers to play with a few settings, here is a new demo:

    I pushed the code on GitHub again.
