Sega Megadrive Synth

This all spanned from wanting to mess with fm but in a tactile way instead of tedious computer crap or menu bars.

Below is the code i have used for it. it is a modified version of the notes and volts midi controller sketch info here, the below has as much functionality as in the first video of the sega megadrive synth, poly mode isn’t working, it should when midi parameter 6 is selected (pin D12) is sends all of the CC commands to all 5 midi channels. but im too dumb to figure it out, ill keep trying and when i have that done, there will be a part 2 video!

big thanks to harry axten on the quick fix to poly mode on the above!

The polyphony is made possible with juha’s code that was made for the gameboy megamachine when i built the poly stuff for that project./

here is juha’s code mentionned in the video below! https://github.com/juhakivekas/midisplitter_2000

Below is a more in depth video

the above video talks more about the inner workings of the beast! to get an idea of how the multiplexers are hooked up check out notes and volts video below :-
