Descriptions of Parameters
Program Editor Parameters
The Timbre Menu
The parameters in the Timbre menu control the most basic components of the sound in a
program. There’s a separate set of Timbre parameters for each program layer.
Keymap
The keymap for programs using mono keymaps (most keymaps are mono keymaps). This
parameter appears as
<<|Keymap|R
for programs using stereo keymaps.
Keymap L >>
The keymap for the left side of programs using stereo keymaps. This parameter appears as
(Keymap)
for programs using mono keymaps, and is inactive (you can’t change its value).
<< Keymap R
The keymap for the right side of programs using stereo keymaps. It appears as
Keymap
for
programs using mono keymaps, and is the only active keymap parameter.
Key Range Low, Key Range Hi
These parameters set the lowest and highest notes for the layer.
DSP Parameters
Each layer uses a set of DSP (digital signal-processing) functions that you can use to modify the
sound of the layer. Every layer of every program is assigned a set of DSP functions (and
associated parameters) at the factory; you can’t change which parameters are associated with
each layer, but you can change the
values
of the parameters.
Every layer has a total of two DSP parameters. Some layers use two single-parameter DSP
functions, while others use one two-parameter function. For example, Layer 1 of Program
016
Classic E Piano
uses two separate lowpass filters, each of which has a single parameter for
setting the cutoff frequency. All the layers in Program
054
Retro Roto
use a two-pole lowpass
filter with parameters for setting cutoff frequency and resonance.
Layers that use single-parameter functions include numbers in their names to distinguish them
from each other. For example, in Layer 1 of
Classic E Piano
, there’s LP Filt[1] and LP Filt[2].
These numbers don’t appear in the parameter names of two-parameter functions.
Not all layers use their allotment of DSP functions. They have one or two parameters called
None to indicate the absence of DSP functions. You can’t change the values of these parameters.
Note
: When you enter the
Timbre
menu, the first parameter you see is the first DSP parameter.
To get to the preceding parameters in the Timbre menu, press the
Left
cursor button one or more
times.
Volume (Amp)
Independent amplitude control for the layer. Use this parameter to make one layer softer or
louder than the others.
