34 Distortion

Dave Smith Instruments

Distortion

The Prophet 12’s stereo analog distortion is actually two stereo distortions, one

for layer A and another for layer B, so that split and stacked sounds can have

different distortion settings per layer.

Distortion:

0…127

—Sets the distortion amount for the current layer.
