Source Audio Atlas Compressor — MIDI Editor & CC Reference

Control the Source Audio Atlas Compressor from your browser — full MIDI CC reference for 6 parameters, interactive editor, and AI-generated presets. Free, no install.

Nitelite gives the Atlas Compressor 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
THRESHOLDCC 2Adjusts the decibel level at which compression begins. Lower values (counterclockwise) set a lower threshold for earlier compression; higher values (clockwise) require a hotter signal before compression occurs.
RATIOCC 3Adjusts the severity of compression. Clockwise for a higher (flatter) ratio and ultra-squashed dynamics; counterclockwise for a lower ratio and more subtle compression.
BLENDCC 4Adjusts the wet/dry mix. Fully counterclockwise = 100% compressed (wet). Fully clockwise = 100% dry (clean). Blending dry signal back in creates parallel compression.
OUTPUTCC 5Adjusts the overall output level (wet/dry mix) of the Atlas. Controls both wet and dry signal levels.

Alt / Secondary Knob Functions

ControlMIDI CCDescription
MAKEUP GAINCC 6Adjusts makeup gain within the compressed (wet) signal to recover lost output volume caused by heavy compression. Only affects the compressed signal, not the dry blend.
TONECC 7Cuts (below noon) or boosts (above noon) treble in the parametric EQ. Default frequency is ~4461Hz. Adjustable via Neuro Editor.
ATTACKCC 8Controls how quickly compression is applied in milliseconds. Clockwise for fast attack times; counterclockwise for slower attack times that let initial transients through.
RELEASECC 9Controls how quickly compression stops being applied in milliseconds. Clockwise for fast release times; counterclockwise for slower release times (more sustained compression).
