A Ring Modulator produces the sum and difference of frequencies in multiple waveforms. This often results in 'robotic' sounds.

The following factory presets feature the Ring Modulator:

  • Trackings Ringmods
  • FilteRING Funk
  • By Your Command


Ring Modulator types

The Ring Modulator has three types:

  • Classic
  • SSB Upper

Parameters table

Type yes
Frequency yes
Frequency Multiplier yes
High Cut Frequency yes
Pitch Tracking yes

Pitch Tracking

When enabled, the frequency of the oscillator tracks the pitch of the notes on the fretboard.

Tips and tricks


The Ring Modulator works great as an Octaver (adding a low octave). Enable Pitch Tracking, set FREQ to 500 Hz, and turn down HIGH CUT FREQUENCY to 500 Hz or lower.

For even more funky business: add a Phaser or an Auto-Wah effect.


You can conturn the Ring Modulator into a Tremolo, by turning down FREQUENCY all the way.

Fixed Flanger

"The Resonator block is basically a type of fixed flanger. Well, four of them in parallel actually." source

Pedal control

Attach a pedal to the FREQ parameter, to create a special effect.

Multitap Delay

The Multitap Delay can apply a ring modulation effect to delay trails.
