Special MIDI Functions

Tap Tempo — CC 93
Expression — CC 100
Pre/Post — CC 22. Selects whether the modulation effect is placed pre-amp (before the amp input) or post-amp (in the effects loop). Saved per preset.
Expression Pedal Enable — CC 60. Enables or disables the expression pedal input for the current preset. When off, the expression pedal has no effect.
MIDI Clock — CC 70. When on, Mobius responds to incoming MIDI Clock messages to sync modulation speed. Saved per preset.
Bypass — CC 102. When on, the Mobius effect is bypassed. When off, the effect is engaged. Bypass mode (True or Buffered) is set in the global menu.
Tap Division — CC 21. Sets the rhythmic subdivision used when tapping tempo. 0=Whole, 1=Half, 2=Quarter (default), 3=Dotted Eighth, 4=Eighth, 5=Triplets, 6=Sixteenth.
MIDI Patch Bank — CC 0. Selects the MIDI patch bank. Send 0 to access presets 00A–63B (MIDI programs 0–127); send 1 to access presets 64A–99B (MIDI programs 0–71). Must be sent before a Program Change.
Phase Reset — CC 125. Resets the LFO phase on all mod machines. Useful for syncing the modulation cycle to a musical cue.

Hardware Presets

Mobius has 200 hardware preset slots, recalled using MIDI Program Change. Saving requires an action on the pedal; follow the hardware preset manager instructions.
