This is .mix. it's a 4 hp mixer with a transistor makeup gain stage copied from the moog cp3, including the rail voltages (a regulator is used to provide the -6v rail).
There are no opamps in this thing at all, and it will be driven into distortion easily. alot of the tones on redshift records are multiple oscillators being distorted by the cp3s.
The output attenuator is bipolar.
