Moog MF-108M Cluster Flux — MIDI Editor & CC Reference

MIDI control for the Moog Moogerfooger MF-108M Cluster Flux analog BBD chorus/flanger — delay time, bipolar feedback, six LFO waveforms and MIDI clock sync.

Nitelite gives the MF-108M Cluster Flux 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

Control	MIDI CC	Description
DRIVE	CC -1	Sets the input sensitivity of the Cluster Flux, from -7dB to +28dB nominal. Only active when the effect is on. Set so the LEVEL LED lights mostly yellow. NOTE: not controllable over MIDI — adjust on the pedal.
OUTPUT	CC 7	Sets the strength of the Cluster Flux output at both the Left and Right audio outputs. Only active when the effect is on. Boost, attenuation or no change can be achieved with any Drive setting.
MIX	CC 14	Blend ratio of dry to wet signal. Fully counterclockwise passes only dry, fully clockwise only wet, anywhere between blends the two. Only active when the effect is on.
TIME	CC 12	Sets the length of delay from the BBD delay line, within the range set by the RANGE switch. In Flange mode with LFO Amount at 0 the delay time runs .6 msec to 10 msec nominal; in Chorus mode 5 msec to 50 msec nominal.
FEEDBACK	CC 13	Amount of BBD output fed back into the BBD input. Bipolar: zero feedback at mid-position, negative below, positive above. In Flange mode positive feedback emphasizes all harmonics of the fundamental, negative shifts the spectrum down an octave so only odd harmonics are emphasized. WARNING: designed to drive the delay line into self-oscillation — oscillation begins at the 4th indicator line either side of centre.
LFO RATE	CC 15	Frequency of the LFO modulating the delay line, .05 Hz to about 50 Hz from the panel. The Rate LED is RED for panel control, GREEN for Tap Tempo, YELLOW when synced to MIDI clock. When synced, the Rate control is quantized to rhythmic subdivisions of the clock tempo.
LFO AMT	CC 16	Overall amount of modulation of the delay time by the LFO. At zero, no modulation is heard. As LFO Amount increases the functional range of the TIME control decreases, so the maximum and minimum delay times are not exceeded.

Special MIDI Functions

MIDI Sync Enable — CC 76. Enables or disables syncing the LFO to MIDI Real Time Clock messages. Enabled by default, and re-enabled every time the unit is powered up. When synced, the LFO Rate LED turns yellow and Tap Tempo is disabled.
Enable LFO Note Reset — CC 73. When enabled, an incoming MIDI Note On message restarts the LFO from the beginning of its waveform. Disabled by default. The value is stored to memory when the unit is powered down.
Enable MIDI Note Mode — CC 77. When enabled, MIDI Note On messages set the delay time — note numbers 0 to 90 are recognised and velocity is ignored, so tuned comb-filter effects can be played from a keyboard or sequencer. Defaults to enabled on every power-up.
Enable MIDI Note Spillover — CC 78. Lets MIDI Notes act as a momentary bypass switch. A Note On turns the effect on; a Note Off stops audio entering the effect but keeps monitoring the effect signal. With enough Feedback this rhythmically "punches in" ringing comb-filter or lo-fi delay effects. Disabled by default.
Delay Time Portamento — CC 5. Sets the rate of change of delay time by ALL controls — the TIME knob, the Time CV input, the LFO and MIDI control of delay time. Larger values slow the rate of change, creating a "glide" effect. Resets to 0 on every power cycle.
LFO Phase Reset — CC 72. Sending any value restarts the LFO from the beginning of its waveform.
