Solid linear mixing with an oft overlooked trick up its sleeve
Martyn Q., 01.10.2015
As a mixer it works a charm, signal quality is more than sufficient for most uses - gets used in every patch without fail. A key feature that it seems most don't realise is there - channel 1 gives a constant cv 0-5v when nothing is plugged in, so can be used to offest cvs that are being mixed in channels 2-4. Most people I've spoken to don't seem to realise that feature is there - neither did I till I read the manual (read it out of curiosity I should add, other than this feature the module is entirely self explanatory).

Super useful
19.01.2017
I think this module comes under the heading of 'very useful, but not sexy'.
I've used it to mix two LFO outputs and then sent that to modulate the filter cutoff, the PWM of the VCO, and also the CV input on the VCA.
Super useful.
