Not so. This is one of the many possible uses for the A136
Distortion/Waveshaper, the other "Swiss Army Knife" module. It can be
used as a simple attenuator, gain stage, overdrive preamp, voltage
inverter, external signal booster, trigger modifier, and a tracking
function generator. Oh, yeah, it also does distortion, and can create
radical waveshapes from an LFO signal.
