I read a recent blog from MusicalAndroid comparing various 303 emulators, and it got me thinking on how to maintain the authentic sound in the Caustic App.
Here is how I set it up:
Distortion Mode Saturate..... Soak it just enough to get the growl and grit in SquareWave Mode PWM knob off a few clicks.
In the Main Mixer.... Low EQ@10:00 MidEQ@1:00 HiEQ@9:00
Try it, you might like how it sounds....
