Pittsburgh Mix Mult

This module combines a three-channel mixer and attenuator with two sets of passive signal splitters, suitable for audio and CV applications.

• Patching into the output of channel 1 or 2 turns those channels into independent passive signal attenuators.
• Channel 3 can function as a buffered attenuator when channels 1 and 2 are used as attenuators.
• The mixer knobs have a logarithmic volume curve tuned for audio but also works with CV.
