Thanks for the reply, but I am not asking witch effects are mono/stereo, but monophonic (not polyphonic, works only for single note playing).

Dimensions? Weight? Helix—22.05 x 11.85 x 3.6 inches; 14.6 lbs. Does the height of 3,6 inches include everything; the expression pedal, knobs and rubber feet? Can the rubber feet be removed?

Which of the effects are monophonic? I would guess the Pitch Ring Mod, Pitch Wham, Twin Harmony and 3 OSC Synth?
