ControlMIDI CCDescription
DEPTHCC 1Controls the depth of the LFO, determining how prominent the tremolo effect is. Fully counter-clockwise nearly bypasses the effect on some types (optical, bias). Fully clockwise gives maximum tremolo prominence.
SPEEDCC 2Controls the frequency of the LFO, determining how fast the tremolo pulses. Different effect types (optical, harmonic, bias) may have different minimum and maximum speeds. When MIDI Clock is active, this controls beat subdivisions instead (quarter/eighth/triplet/sixteenth notes).
SHAPECC 3Sets the LFO waveform shape. Fully counter-clockwise is a square wave, center is a sine wave (or optical shape for Normal type), and fully clockwise is a falling sawtooth wave. Intermediate positions blend between adjacent wave shapes.
LEVELCC 4Sets the overall output level. Linear control from 0 (silent) to 2.0 (+6 dB). Middle position (64) is unity gain (0 dB). Quarter position is -6 dB (0.5), three-quarter position is +3.5 dB (1.5).
