Lexicon MPX 100 User Manual

Pitch
The stereo polyphonic Pitch program in
the MPX 100 allows complete program ma-
terial or monophonic sources to be shifted
down two octaves or up one octave.
For pitch correction, use this algorithm
with Mix set to fully Wet. For harmonization,
use the desired amount of wet/dry Mix.

Altering the pitch of a sound allows a variety of effects from subtle detuning to
the creation of harmonies and chords.
