Pittsburgh Modular Mixer Eurorack Module
The Pittsburgh Modular Mixer is a simple, low-noise four channel mixer and/or attenuator for audio and cv that can be used in multiple different ways. The pots are wired with a logarithmic volume curve that is tuned for use with audio but it will work with CV as well. Patching the output of channel 1, 2, or 3 will remove it from the mixer circuit. Channel 4 can not be removed from the mixer circuit, however if channel 1, 2, and 3 are all being used as attenuators, channel 4 is the only input remaining in the mixer allowing it to be used as a buffered attenuator.
