..
here I am messing around with sending audio from roland tb303 into boss syb-3 pedal and then into boss os-2 pedal, the audio is be routed via ableton live using external effects and motu ultralite, I go through a number of the boss syb-3 settings and the boss os-2 settings, you can hear how it tracks the tb303 bassline.
The drum is the bassdrum from tr606 with some overdrive in live.
enjoy
