Universal Audio MAX — MIDI Editor & CC Reference

Control the Universal Audio MAX from your browser — full MIDI CC reference for 8 parameters, interactive editor, and AI-generated presets. Free, no install.

Nitelite gives the MAX 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.

Knobs

ControlMIDI CCDescription
PREAMPCC 22Comp 1 UA 610 tube preamp level. Increase to add drive and harmonics. Fully counter-clockwise (0, OFF) disables the preamp and its EQ — Comp 1 has clean unity gain. Just above OFF keeps preamp EQ active without tube coloration.
COMPCC 25Comp 1 compression amount. Clockwise for more squeeze and sustain. Level is auto-compensated as compression rises. On OPTO LA-2A and FET 1176 models, minimum silences the signal — rotate up to hear output. On DYNA this is the original hardware's Sensitivity control.
OUTPUTCC 26Comp 1 pedal output level. In Parallel mode, used to balance a heavily compressed path against a less compressed path.
ATTACKCC 27Comp 1 attack time (FET 1176 only). Onset speed after the signal crosses the threshold — clockwise for FASTER attack, matching the original 1176 hardware. Has no effect on DYNA or OPTO LA-2A.
RATIOCC 28Comp 1 compression ratio. Behavior depends on the Comp 1 model. OPTO LA-2A: 4:1 matches the original hardware's COMP setting, 20:1 / ALL matches LIMIT mode, OFF gives circuit color with no compression. FET 1176: 4:1 to 20:1, ALL is the famous 'all buttons in' response, OFF gives circuit color only. Unused on DYNA. Step values are 0, 20, 50, 80, 110, 127.
RELEASECC 29Comp 1 release time — recovery speed after compression. Clockwise for FASTER release. OPTO LA-2A: the original hardware has no release control; noon matches the original. FET 1176: adjusts the original hardware release. Unused on DYNA.

Alt / Secondary Knob Functions

ControlMIDI CCDescription
PREAMPCC 32Comp 2 UA 610 tube preamp level (ALT). Increase to add drive and harmonics. Fully counter-clockwise (0, OFF) disables Comp 2's preamp and its EQ for clean unity gain.
COMPCC 35Comp 2 compression amount (ALT). Clockwise for more squeeze and sustain. On OPTO LA-2A and FET 1176, minimum silences the signal.
OUTPUTCC 36Comp 2 pedal output level (ALT). In Parallel mode, used to balance a heavily compressed path against a less compressed path.
ATTACKCC 37Comp 2 attack time (ALT, FET 1176 only). Clockwise for faster attack. No effect when Comp 2 is set to DYNA or OPTO LA-2A.
RATIOCC 38Comp 2 compression ratio (ALT). Steps: OFF / 4:1 / 8:1 / 12:1 / 20:1 / ALL. Unused on DYNA.
RELEASECC 39Comp 2 release time (ALT). Clockwise for faster release. Unused on DYNA.

Special MIDI Functions

  • Comp 2 Bypass — CC 20. Bypasses Comp 2 (0 = Bypass, 1 = Unbypass). In Exclusive mode engaging Comp 2 disengages Comp 1.
  • Comp 1 Sidechain Bass Filter — CC 30. Comp 1 sidechain bass filter (FET 1176 only). Removes low-frequency content from the compressor's control sidechain to reduce pumping on bass-heavy signals without affecting the audio's bass content.
  • Comp 2 Sidechain Bass Filter — CC 40. Comp 2 sidechain bass filter (FET 1176 only). Reduces pumping on bass-heavy signals without affecting the audio's bass content.
  • Comp 1 Preamp Low EQ — CC 23. Comp 1 UA 610 preamp 100 Hz low shelf. 0 = -6 dB cut, 1 = Flat (off), 2 = +6 dB boost. Inactive when Comp 1 Preamp knob is OFF.
  • Comp 1 Preamp High EQ — CC 24. Comp 1 UA 610 preamp 10 kHz high shelf. 0 = -6 dB, 1 = Flat, 2 = +3 dB, 3 = +6 dB. Inactive when Comp 1 Preamp knob is OFF.
  • Comp 2 Preamp Low EQ — CC 33. Comp 2 UA 610 preamp 100 Hz low shelf. 0 = -6 dB, 1 = Flat, 2 = +6 dB. Inactive when Comp 2 Preamp knob is OFF.
  • Comp 2 Preamp High EQ — CC 34. Comp 2 UA 610 preamp 10 kHz high shelf. 0 = -6 dB, 1 = Flat, 2 = +3 dB, 3 = +6 dB. Inactive when Comp 2 Preamp knob is OFF.
