FX Width
FX Width can be thought of as an extension of typical mono to stereo imaging
controls. The range of this parameter is -360 to +360, in single digit increments.
Values of -360, 0, or +360 cause the effect's audio output to be mono. Values
of -315 and +45 cause the output to be normal left/right stereo. Values of -45 and
+315 cause "swapped", or right/left stereo.
Value Display Label Description
360 MONO Phase Normal Mono
315 R, L Phase Normal R/L stereo
270 R–L, L–R R–L, L–R surround
225 STEREO INV Phase Inverted L/R Stereo
180 MONO INV Phase Inverted Mono
135 R, L INV Phase Inverted R/L Stereo
90 L–R, R–L L–R, R–L surround
45 STEREO Phase Normal L/R stereo
0 MONO Phase Normal Mono
-45 R,L Phase Normal R/L Stereo
-90 R–L, L–R Phase Inverted R–L, L–R surround
-135 STEREO INV Phase Inverted L/R Stereo
-180 MONO INV Phase Inverted Mono
-225 R, L INV Phase Inverted R/L Stereo
-270 L–R, R–L L–R, R–L surround
-315 STEREO Phase Normal L/R Stereo
-360 MONO Phase Normal Mono
The large and duplicated range of this parameter allows smooth glides from any
Left/Right Mix, Phase, Mono/Stereo image point to any other. These are on the
output of the FX Mix. Of particular interest are: 0 MONO, 45 STEREO, and 90
L–R, R–L (surround channel). This parameter can be changed in real-time for
fascinating spatial effects.
ADJUST
This control allows you to specify the range of control of the ADJUST knob when
it is patched to a parameter. Low and High settings are available, allowing you
to select full range (0-127) for those parameters where it is appropriate and to
limit the range in other cases. You can, for example set the Low value to 0, and
the High value to 1, to have ADJUST behave as an on/off control. Many of the
presets take advantage of this, and have ADJUST range limits which are
appropriate to the specific parameter.
