a little mess..

 

SInthai Solo

 

This little monophonic FM synth is based on Hagiwo's FM Oscillator ,it's just Arduino with the help of AI and therefore not Duophonic at least , but i decided to keep it , it's got 7 waveforms ,envelope ,pitch bend with 2 semitones ,range and depth controls , there are dedicated cv inputs for all these functions , now there was room on the panel to add a simple envelope generator as there is pulse out on keypress at D1 , but guess i'll just do that part separate ,the Joystick is just voltage source to modulate inputs . It's all done on stripboard .The keyboard is cut out from larger Casio CT660.
