The DSP Functions
16-45
Distortion (DIST)
Using this function is much like overdriving an ordinary keyboard or guitar ampliÞer. The input
signal is multiplied by the gain control (the combined values of the parameters on its
control-input page labeled DRV, for Drive), then passes into a distortion mapper. Large Adjust
values will cause serious amounts of distortion.
Different sounds are affected differently by DIST. Waveforms that are static (waveforms with
shapes that repeat regularly and are not evolving) when they enter the DIST function will
undergo more of a timbre change than the familiar sound of distortion.
The DIST function distorts each note separately, unlike a fuzz box, which adds several notes
together then applies a uniform amount of distortion to all of them. Consequently your power
chords may sound a little different from your expectations, but you can also get some great
effects with key and velocity tracking (not to mention Sources 1 and 2!) that arenÕt possible with
other distortion devices.
