Meris Polymoon — MIDI Editor & CC Reference

Control the Meris Polymoon from your browser — full MIDI CC reference for 9 parameters, interactive editor, and AI-generated presets. Free, no install.

Nitelite gives the Polymoon a full browser-based control surface: turn every knob, flip every switch, describe the tone you want to the AI Tone Terminal, and save the results — all sent to the pedal live over MIDI (default channel 1). Works free in Chrome, Edge, Opera, or Brave — no install required.

Footswitches

  • TAP — bypass on CC 28
  • BYPASS — bypass on CC 14

Special MIDI Functions

  • Tap Tempo — CC 28
  • Expression — CC 4
  • Bypass — CC 14. When on, the effect is bypassed (dry signal only). When off, the effect is engaged. Per Meris spec: 0–63 = FX bypass, 64–127 = FX enabled.
  • Tempo — CC 15. Sets the delay time directly in 10 ms increments (0 = 0 ms, 120 = 1200 ms). Use instead of tap tempo for precise delay time control via MIDI.

Hardware Presets

The Polymoon has 16 hardware preset slots. Nitelite can save your current settings to a slot and recall slots via MIDI program change.
