thanks guys, yes the idea is to is to use the ocoast along with the a4.
so i could use one track output of th a4 to modulate the ocoast. i also have a mini modular system called tinysizer. wich on its own has two osc and fm options but the wave shaping options seems to be pretty limited.
i hesitate to start with the eurorack thing.
@Unifono is there something special to the make noise wavefolder/ waveshaper?
