Control the Empress Effects Echosystem from your browser — full MIDI CC reference for 19 parameters, interactive editor, and AI-generated presets. Free, no install.
Nitelite gives the Echosystem 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.
| Control | MIDI CC | Description |
|---|---|---|
| A DELAY TIME | CC 101 | Delay time for Engine A. In tap mode this controls the ratio of the delay time relative to the tapped tempo. A value of 0 is fully counter-clockwise (shortest time / lowest ratio), 127 is fully clockwise (longest time / highest ratio). Range is approximately 20ms to 1.2s in knob mode for most delay types. |
| A MIX | CC 102 | Wet/dry mix for Engine A. Counter-clockwise is 100% dry (no delay), clockwise is 100% wet. The 50/50 balance point is around 2 o'clock. Use this to set how prominent the delay repeats are in the overall signal. |
| A OUTPUT | CC 103 | Overall output volume for Engine A. 12 o'clock (value ~64) is unity gain. Turn down to tame loud delay modes, or boost to push the signal harder. |
| A FEEDBACK | CC 104 | Controls how long Engine A's delay takes to decay — the number of repeats heard. Low values give a single slapback repeat; high values produce long trails of regenerating echoes. At maximum the delay can self-oscillate. |
| A TONE | CC 105 | EQ applied to Engine A's delay line. Center position is neutral. Counter-clockwise rolls off highs for darker, warmer repeats; clockwise brightens the repeats. Use this to shape the character of the echoes. |
| A THING 1 | CC 106 | Mode-specific parameter for Engine A. Function changes depending on the active mode — controls things like modulation depth, pan width, saturation, swell time, duck amount, vibrato amount, pulse center frequency, filter sensitivity, grain size, drive amount, or pitch settings. Check the Mode Reference Chart for the specific function in each mode. |
| A THING 2 | CC 107 | Second mode-specific parameter for Engine A. Function changes depending on the active mode — controls things like modulation rate, pan speed, bandwidth, release speed, chorus amount, diffusion, reverb decay, tremolo depth, pulse speed, response speed, swoosh speed, compression amount, or pitch of delay 2. Check the Mode Reference Chart for the specific function in each mode. |
| B DELAY TIME | CC 110 | Delay time for Engine B. In tap mode this controls the ratio of the delay time relative to the tapped tempo. A value of 0 is fully counter-clockwise (shortest time / lowest ratio), 127 is fully clockwise (longest time / highest ratio). Range is approximately 20ms to 1.2s in knob mode for most delay types. |
| B MIX | CC 111 | Wet/dry mix for Engine B. Counter-clockwise is 100% dry (no delay), clockwise is 100% wet. The 50/50 balance point is around 2 o'clock. Use this to set how prominent the delay repeats are in the overall signal. |
| B OUTPUT | CC 112 | Overall output volume for Engine B. 12 o'clock (value ~64) is unity gain. Turn down to tame loud delay modes, or boost to push the signal harder. |
| B FEEDBACK | CC 113 | Controls how long Engine B's delay takes to decay — the number of repeats heard. Low values give a single slapback repeat; high values produce long trails of regenerating echoes. At maximum the delay can self-oscillate. |
| B TONE | CC 114 | EQ applied to Engine B's delay line. Center position is neutral. Counter-clockwise rolls off highs for darker, warmer repeats; clockwise brightens the repeats. Use this to shape the character of the echoes. |
| B THING 1 | CC 115 | Mode-specific parameter for Engine B. Function changes depending on the active mode — controls things like modulation depth, pan width, saturation, swell time, duck amount, vibrato amount, pulse center frequency, filter sensitivity, grain size, drive amount, or pitch settings.

| B THING 2 | CC 116 | Second mode-specific parameter for Engine B. Function changes depending on the active mode — controls things like modulation rate, pan speed, bandwidth, release speed, chorus amount, diffusion, reverb decay, tremolo depth, pulse speed, response speed, swoosh speed, compression amount, or pitch of delay 2.
