Electro-Harmonix Mono Synth

Mono Synth
Transform your guitar into eleven great sounding synthesizers!

The EHX Mono Synth transforms your guitar into eleven great sounding synthesizers… from vintage synth emulations to fat, stacked voices to soaring lead sounds and more.

The Mono Synth was designed to work on guitar without any modifications, special pickups or MIDI implementation. Its intuitive layout makes it easy to use and easy to dial in cool sounds quickly. The pedal’s DRY dial adjusts the dry guitar volume at the Synth Output while SYNTH controls the volume of the synthesizer sound at the Synth Output. Used together they let you create just the right mix. The SENS control, short for sensitivity, adjusts how playing dynamics trigger the synthesizer and allows you to fine-tune the pedal’s response to your guitar and playing style.

With the CTRL knob you can adjust a key parameter for each of the eleven synth types. It varies depending on the preset and provides extra tweakability for customizing your sound. There’s also an EXP input which lets you control an entirely different parameter in real-time with an expression pedal!

Using the built-in Preset footswitch, a user customizable preset for each of the eleven synth sounds can be created, saved and recalled. The factory presets are also easy to restore should you wish to.

Controls:

1. DRY VOL: Controls the volume of the untreated input signal present at the SYNTH OUTPUT jack.
2. SYNTH VOL: Controls the overall volume of the synthesizer sound at the SYNTH OUTPUT jack.
3. SENS: Adjusts the gain of the input signal before the signal hits the Mono Synth’s (MS) trigger block.
4. CTRL: Control a specific parameter for each synth type.

SYNTH TYPE DESCRIPTIONS:

1. NU WAVE – pulsating string-like synth.

• CTRL: the CTRL knob sets the cutoff frequency of the filter.
  
• EXP: the expression pedal sets pitch modulation depth. As the pedal is swept from heel to toe, modulation depth increases.

2. UNISON – the huge sound of stacking voices on a polyphonic synth.

• SENS: higher settings make for wider filter sweeps.
  
• CTRL: controls the volume of a separate oscillator tuned a Perfect 5th higher than the incoming pitch.
  
• EXP: controls the cutoff frequency of the filter.

3. BLAST – aggressive and resonant synth with deep filter modulation.

• SENS: higher settings make for wider filter sweeps.
  
• CTRL: controls the resonance or frequency peak width of the filter.
  
• EXP: controls the frequency range of the filter envelope. The filter’s frequency range increases as the pedal is swept from heel to toe.

4. TWIN – a throaty, dual filter synth sound.

• SENS: higher settings make for wider filter sweeps.
  
• CTRL: sets the decay time of the filter envelopes.
  
• EXP: controls the filter envelope’s sweep depth or frequency range.

5. BASS – octave-down synth for adding low end.

• CTRL: adjusts both the decay time and sweep depth of the filter.
  
• EXP: controls the filter’s cutoff frequency. As the pedal is swept from heel to toe, the cutoff frequency increases.

6. XOX – fast decaying synth reminiscent of the TB.

• SENS: higher settings make for wider filter sweeps.
  
• CTRL: sets the decay time of the filter envelope.
  
• EXP: controls the filter’s cutoff frequency.

7. WUB – pulsating synth with a modulating filter.

• SENS: higher settings make for wider filter sweeps.
  
• CTRL: sets the speed of modulation.
  
• EXP: controls the filter’s center frequency.

8. TINKER – quirky synth great for bell-like tones.

• CTRL: controls the filter’s cutoff frequency.
  
• EXP: controls the pitch of the added note in half-step increments. The pitch ranges from -1 octave—at the heel—to +4 octaves—at the toe.

9. LAIR – a dramatic, expressive synth with expression filter control.

• SENS: higher settings make for wider filter sweeps.
  
• CTRL: adjusts both the filter’s decay time and frequency range.
  
• EXP: controls the filter’s cutoff frequency.

10. GHOST – haunting synth tone with a warbling modulation effect.

• CTRL: this knob sets the depth of VCO pitch modulation.
  
• EXP: sets the rate of modulation which increases as the pedals is swept from heel to toe.

11. BLISTER – piercing synth with an added adjustable pitched note.

• CTRL: detunes the oscillator. The noon position yields no detune. Turn clockwise from noon to detune sharp or counter-clockwise from noon for flat detune. The further you turn from noon, the more detune.
  
• EXP: controls the pitch of the added note in half-step increments. The pitch ranges from -1 octave—at the heel—to +4 octaves—at the toe.
