CGM Channel (C)

Frap Tools

The C (Channel) module is a discontinued mono channel strip for the CGM Creative Mixer system. Its signal routing provides VCA input gain, two effect sends (pre/post fader), stereo pan with CV input, a channel fader, and a direct output. CV controls are available for VCA level, effect send levels, and pan. Creative functions include Mute, Solo in Place, and PFL.593

Audio Mixeraudio-mixer
Mono channel strip for the CGM system — handles input gain, effect sends, pan, and fader for routing to a Group module.593
Voltage Controlled Mixervoltage-controlled-mixer
VCA level, pan, and both effect send levels are voltage-controllable via dedicated CV inputs.593

Parameters 9

NameTypeRangeBehavior
Channel FaderfaderSets the audio signal volume to be sent to the Group module. Controls the amplitude of the signal going out to the mix.593
Direct Out Pre/PostswitchSelects whether the Direct Output taps the signal pre-fader (upper position, red dot) or post-fader (lower position, white dot).593
Effect Send Pre/PostswitchSelects whether the effect send level is pre-fader (independent of channel fader) or post-fader (relative to channel fader position).593
LevelknobControls the input VCA gain. When a CV is patched to the VCA Level CV Input, the knob becomes an attenuator for that CV. The VCA can go above unity gain, adding smooth saturation.593
Mute ButtonbuttonCloses the main VCA, equivalent to turning the Level knob to zero. Mutes all outputs including effect sends.593
PanknobDistributes the processed signal across the left and right channels for the Group module. CV input acts as an offset (not attenuator) — positive CV shifts toward right, negative toward left.593
PFL ButtonbuttonSelects the channel to be sent to the PFL (Pre-Fader Listening) circuit on the Master module, allowing pre-fader monitoring through headphones.593
Send LevelknobTwo Send Level knobs define the amplitude of the channel signal routed to the group's effect sends mono outputs. Each features a CV input and a pre/post fader switch.593
Solo in PlacebuttonSelects the channel to keep active when the group is in Safe Solo mode. Channels with Solo in Place active are soloed; others are muted.593
