Eventide PitchFactor — MIDI Editor & CC Reference

Control the Eventide PitchFactor from your browser — MIDI control reference, interactive editor, and AI-generated presets. Free, no install.

Explore the PitchFactor controls in your browser and connect compatible MIDI hardware to send settings to your pedal. The reference below shows the controls mapped in Nitelite; available functions depend on the pedal and firmware. The default MIDI channel in Nitelite is 1. Browser MIDI control works in Chrome, Edge, Opera, or Brave — no install required.

Footswitches

ACTIVE — CC 33
FLEX — CC 34
TAP — CC 35

Special MIDI Functions

Tap Tempo — CC 35
Expression — CC 15
Bypass — CC 33. When on, the pedal is bypassed (dry signal only). When off, the effect is engaged. Mirrors the left (Active) footswitch.
Flex / Learn — CC 34. Activates the Flex function (or enters Learn mode when held). Mirrors the center footswitch. Behavior depends on the current effect algorithm.

Hardware Presets

PitchFactor has 100 hardware preset slots, recalled using MIDI Program Change. Saving requires an action on the pedal; follow the hardware preset manager instructions.
