Here’s my very simple volume pedal patch with a variety of extra features. Mainly made for my own use, and also a fairly old patch, with its initial design from some time in the Zoia firmware 1.xx period — hence the messy pages containing the guts of the patch.

Page 0 contains the controls & readout display as follows (letters left to right, numbers top to bottom):
A1-A3: Expression source (CVport/exp, onboard, MIDI)
B1-C1: Input indicator
D1-E5: Current volume amount readout
F1-G1: Output indicator
B2: onboard volume control
B3: midi cc in (default: Ch8, CC5)
A4: Left channel status
C4: Phase/polarity status (Green: in phase – Red: out of phase – off: summing to L or R)
F4: mute latch/momentary status
H4: Right channel status
A5-B5: mute indicators (red: muted)
C5: output mode sw (cycles normal stereo, L only, out of phase stereo, R only)
F5: latch/momentary mode sw (swaps between mute & killswitch modes)
G5-H5: mute indicators
