I did this patch myself, it emulates all functions of the TB-303.
The knobs are also the same as the TB-303 :
Knob 1 : volume Knob 2 : Wave selector (square or saw] 6 bottom knobs = the 6 original TB-303 knobs : Tune - Freq - Res - Env mod - Decay - Accent Please note the you also have the possibility to add an external mono audio signal, which will be mixed with the TB-303 sound !!!
The patch is downloadable as a PCH format HERE.
