1 PHILOSOPHY AND DESIGN
The CGM Creative Mixer is a modular mixing solution
for Eurorack modular systems. It is designed to obtain a
flexible setup, providing all the tools you may need in stu-
dio and during a live performance, as well as plenty of
CV inputs for every possible automation.
It is currently composed of three modules: the Channel,
the Group and the Master.
The Channel accepts mono signals. It has a main stereo
VCA with CV in and attenuator (red), a direct output
post-main VCA (pre or post fader), two parallel voltage-
controlled effect sends with individual attenuators and
pre/post fader switches (yellow and green), and a PAN
control with offset CV and offset pot. This, together with
the latching buttons for mute, solo in place, and PFL,
manages the incoming signal and distributes it to the
Group module.
The Group gets and sums the L/R post-fader signals
(white) of all the linked Channels, sums all the signals from
the yellow and green sends, and manages the sends
(mono) and returns (dual mono or stereo), summing it to
the signals from the Channels. It also manages the Solo-In-
Place activation on all the linked Channels and provides a
L/R output for the outgoing signal, or (via a jumper on
the back of the module) a L/R output of the sum of the
return signals. Up to eight Channels may be connected to
a single Group, taking care also of its powering. You can
connect also up to four Groups to a Master module.
The Master sums the incoming signals from the Groups
and manages the Pre-Fader Listening (PFL, stereo) of both
Channels and Groups. It also features an auxiliary stereo in
via a 3.5 mm stereo jack with PFL latching button and a
stereo out via 3.5 mm stereo jack for headphones, whose
signal can be blended between PFL and main out.
