★ 4-voice audio submix
Four voice outs → Input 1-4 · balance with Level 1-4 · Output → main mixer · compact submix for drum or chord voice group that otherwise eats HP

Behaviors

DC coupling any CV patched

All inputs and the output are DC-coupled, so CV, envelopes, gates, and pitch signals pass unchanged. Useful for summing offsets, mixing modulation sources, or combining multiple gate signals into one.

Unity gain only all knobs fully CW with multiple inputs

Knobs are pure attenuators — maximum gain is unity. Summing four full-level signals drives the output near +/-20V peak on CV or produces loud audio peaks. Back off individual knobs to keep the sum inside eurorack range.

CV offset summing multiple offset sources at inputs

Because each input is DC-coupled with its own attenuator, Mix functions as a weighted offset adder. Great for combining a pitch sequence with an octave switch voltage, or summing LFO plus sequencer modulation on a single cutoff line.
