Controls cont'd. 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.
