PCM 80 User Guide
The Parameters PCM 80 parameters are organized into labeled rows within each edit matrix.
Although there are similarities among all matrixes, such as having a row of
Controls first, and Modulation and Patching rows last, some of the parameters
within each row, and some entire rows are unique to specific algorithms.
This section contains descriptions for all PCM 80 parameters, organized
alphabetically by row label as follows:
Chorus
Controls
Delay Time
Feedback/Cross-Feedback
Filters
Glide FX
Levels
Modulation
Panning
Patching
Pitch
Resonance
Rvb Design
Rvb Time
Individual parameter descriptions within each row are presented, as far as
possible, in the order in which they appear from left to right in the edit matrix.
In the Chorus+Rvb algorithm, Row 5 provides parameters which provide rate
and depth controls for each of the six chorus voices, as well as master rate and
depth controls.
MstDepth and MstRate
Two Master Chorus parameters in the first row position allow Chorus, Depth and
Rate for all voices to be simultaneously scaled. Each control has a range of 0-
200%. Press Load/
✱ to toggle between MstDepth and MstRate.
Voices (Depth and Rate)
Each voice position has Depth and Rate controls to set the time range (delay)
and rate of change across that time range (pitch) of the chorusing effect. (Press
Load/
✱ to toggle between them.) Depth provides settings of 0-500ms in single
millisecond increments. Rate parameter can be set to 0Hz (Off), or to one of one-
hundred selections from 0.01-3.50Hz. Depths of 10-30ms combined with Rates
as high as 0.50Hz provide subtle chorusing and multivoicing effects. Depths of
hundreds of milliseconds combined with higher Rates provide a wide range of
pitch shifting effects.
