Knobs

ControlMIDI CCDescription
PITCHCC 23Base pitch in semitones relative to the input signal. In Mono/Poly/Arp modes, transposes the synth relative to the input note. In Dry modes, pitch-shifts the incoming signal directly.
FILTERCC 39Filter cutoff frequency. Higher values produce a brighter, more open sound; lower values a darker, filtered sound.
MODCC 61Amount of pitch change from the oscillator modulation LFO. Low values create a gentle warble; high values create a deep, sea-sick pitch shift excellent for special FX patches.
LEVELCC 35Overall output level of the Oscillator section. Sets the foundation of the synth sound and drives subsequent processing (Drive, Modulate, Ambience).
OSC 1 SHAPECC 24Waveshape for oscillator 1 — Saw (buzzy/bright), Triangle (smooth) or Square (hollow/nasal). Saw pairs well with Ladder filter for classic analog leads.
OSC 2 SHAPECC 25Waveshape for oscillator 2. Adding Triangle to OSC 2 creates deep sub bass; Square in Mono Synth mode recreates woodwind-like sounds.
OSC 2 PITCHCC 26Semitone pitch offset for oscillator 2 relative to oscillator 1.
OSC 2 DETUNECC 27Fine detune for oscillator 2 to thicken the overall preset sound.
OSC 1 GAINCC 29Individual volume of oscillator 1 (0-100%). Use modifiers or expression to create interesting fades between the two oscillators.
OSC 2 GAINCC 30Individual volume of oscillator 2 (0-100%).
XMODCC 31Cross-modulates OSC 2 by OSC 1 frequency. Useful for metallic, FM tones. Try setting OSC 1 Gain to 0% while adjusting XMOD to clearly hear the cross modulation effect.
GLIDECC 28Smoothly bends between notes creating a portamento effect. The amount of Glide determines the speed of the portamento.
MIXCC 1Balance between dry and wet signal. Uses a custom taper; Dry Trim and Wet Trim fine-tune the levels relative to this setting.
DRY TRIMCC 2Fine-tunes the dry signal level relative to Mix. When both trims are set to zero, the Mix parameter operates with its default taper.
WET TRIMCC 3Fine-tunes the wet signal level relative to Mix.
DRY BLENDCC 36In Dry Mono and Dry Poly modes, sets the amount of dry (unshifted) signal blended into the pitch-shifted output. Set to zero for a fully pitch-shifted sound.

Special MIDI Functions

  • Expression — CC 4
  • Bypass — CC 14. When on, the effect is bypassed (dry signal only). When off, the effect is engaged. Per Meris spec: 0–63 = FX bypass, 64–127 = FX enabled.
  • Direction — CC 52. Direction toggle labeled "Direction" in the Enzo X MIDI CC Table. 0-63 = Up, 64-127 = Down. The manual does not label which section owns this CC; context suggests arpeggiator or filter envelope direction.
  • Tempo (7-bit) — CC 15. Sets the main timing directly as a 7-bit value (0-127). Tempo can be expressed in Seconds or BPM via the TEMP DISP setting in Globals.
  • MIDI Clock — CC 21. Controls how this preset responds to incoming MIDI Beat Clock. 0-42 = Use Global (follows the Globals MIDI Clock setting); 43-85 = Force Listen (always accepts MIDI Beat Clock); 86-127 = Force Ignore (always ignores MIDI Beat Clock).
  • Osc Mod Speed — CC 60. Speed of the dedicated pitch modulation LFO for the oscillators (in Hz). Used with Osc Mod Depth (front panel MOD) to create vibrato effects.
  • Osc Mod Ramp — CC 62. Time it takes for the oscillator pitch modulation to ramp up to maximum depth after a note is detected.
  • Filter Resonance — CC 41. Emphasizes a narrow band around the cutoff frequency. High resonance gives a sharp, aggressive filter; lower values create a smooth response. Labeled "Bandwidth" in the State Variable and Twin filters.
  • Filter Noise — CC 42. Output level of the white noise generator mixed in with the oscillators before the filter. Useful for adding texture and noise-based sounds.
  • Twin Filter Spread — CC 43. In Twin filter mode, the distance between the two resonance peaks. At 100% the parallel filters perfectly overlap; toward zero the secondary filter sweeps down toward 0 Hz.
  • Filter Env Amount — CC 44. Amount the Filter Envelope modulates the filter cutoff. Positive settings raise the cutoff; negative settings lower it. 0% removes the Filter Envelope from the filter.
  • Filter Env Depth — CC 53. Depth (intensity) of the Filter Envelope modulation applied to the filter cutoff.
  • Filter Attack — CC 47. Time for the Filter Envelope to ramp up to its peak after a note is played.
  • Filter Decay — CC 48. Time for the Filter Envelope to ramp from the peak down to the Sustain Level.
  • Filter Sustain Time — CC 49. Duration the Filter Envelope is held at the Sustain Level before the release phase begins.
  • Filter Sustain Level — CC 50. Level of the Filter Envelope during the Sustain phase (0-100% of peak).
  • Filter Release — CC 51. Time the Filter Envelope takes to ramp from the Sustain Level down to zero after the note is released.
  • Amp Attack — CC 55. Time for the Amplitude Envelope to ramp up to its peak after a note is played. Longer values create slow volume swells.
  • Amp Decay — CC 56. Time to ramp from peak volume down to the Sustain Level. With Sustain Level at 0%, Decay determines the length of stab notes.
  • Amp Sustain Level — CC 57. Volume level held during the Sustain phase of the Amplitude Envelope (0-100% of peak).
  • Amp Sustain Time — CC 58. Duration the Amplitude Envelope is held at the Sustain Level. Not applied when controlling Enzo X via MIDI IN (held by the MIDI note duration instead).
  • Amp Release — CC 59. Time for the volume to fade to silence after the note is released. Set Attack/Decay/Sustain to zero and Release to 2-3 seconds to create harp-like pluck patches.
  • Note Persist — CC 54. Shapes how Enzo X follows the natural volume curve of the guitar input. Higher values make synthesized notes last longer; lower values create tighter tracking of the input volume. Not applied when controlling Enzo X via MIDI IN.
  • Arp Mode — CC 32. Arpeggiator pattern selector. In Enzo mode the notes play in order of loudness; Up plays ascending; Down plays descending; Up/Down alternates. The manual does not publish explicit CC ranges for the four modes.
  • Arp Steps — CC 33. Number of steps in the arpeggio pattern (1-16). Higher values create longer sequences.
  • Arp Octaves — CC 34. Number of octaves the arpeggio spans (1-3). Higher values create wider-ranging arpeggios.
  • Toggle Tuner — CC 117. Activates the chromatic tuner. Send value 127 to engage Tuner mode (equivalent to holding footswitches 3 + HOLD MODIFIER on the pedal).
  • Hold Modifier — CC 118. Triggers the Hold Modifier function (momentary). Send 127 to press, then send 0 to release. Always send a release (0) after every press.
