Please, add older verion of Nanosynth here.
(with C source code)
The only difference against the other Nanosynth rom is, that when you hit Start, it doesn't switch between mono / stereo delay mod, but it switches between normal / sync mod
in Sync mod it waits for triggering:
I remember that connecting 2 of GB serial's pins triggers a note, disconnecting these pins triggers another note etc...
You can try it alone, or I can try it same as you from a scratch
There was (maybee!) some other thing to do, connect one of another pins to ground. I actually don't remember that. It's more than year I tried to work with this rom.
Don't you want to try to make some easy 4ppqn (CV gate clock / Volca series clock?) to this clock convertor?
I think it could be interesting to have this sync function working and jam with other gear in sync.
