 Distortion amount. Enough said.

Patch Tutorial

Patch a signal with lots of dynamics and harmonic content like a 

drum loop into the Filter In jack. Engage the Laser section and 

hear how the envelope follower shapes the filter to the sound. 

Patch 3:

Patch a simple waveform like a saw wave to the filter In jack. 

Patch the mangle Out jack to your mixer. Play with the Frq, Q, 

Mod, and Mangle parameters to hear what it can do. 

Patch 1:

 

Patch 2:

 

Patch a sound to drive In. Patch Drive Out to Filter In, and Filter 

Out to your mixer. Now you can distort your sound before the 

filter! Cool!
