Qu-Bit Chord Designed To Bring Polyphony To Eurorack Modular Synthesizers

Qu-Bit-Chord-sideQu-Bit has introduced Chord, Eurorack module designed to bring polyphony to your modular synthesizer.

It is a four-voice oscillator, with individual and summed outputs. All voices are tuned together, allowing for quick and easy sequencing of chord progressions.

Outputs morph through sine, triangle, sawtooth, and square waveforms, offering a timbre control that ranges from subtle waveshaping, to powerful spectral filtering.

In addition to its robust synthesis engine, the harmonize function can choose appropriate chord types based on an incoming bassline at the v/oct input.


  • Tuned chords
  • Morphing between waveforms
  • Harmonize feature can choose chord quality based on incoming bassline CV
  • Doesn’t require music theory knowledge

Heres the official video intro:

Pricing and Availability

The Qu-Bit Chord is available now for US $399.

  1. hmm… the way to bring polyphony into modulars is imho on the controller side. For instance a MIDI-interface that split each played note in a chord into a separate MIDI-channel then routing it all out to a multiple of CV/Gates. It may already exist as far as I know.

    1. Definitely.

      Everyone has several full voices in their Euro already. Controlling them in sync is what gets tough.

      This module seems to defeat a lot reason for making building a modular in the first place.

      I like the “doesn’t require music theory knowledge” If there was ever a motto for lots of new music….

      1. Gotta respectfully disagree with Eivind & Caligari here.

        Splitting a 4 note chord at the controller stage means having 4 of the same oscillator to make a conventional sounding chord. Then there’s the need to sum/mix the 4 oscillators before sending to filters etc. This module saves a lot of hassle & routing. Plus it’s cheaper than buying 4 oscillators & a mixer.

        At what point would this defeat a lot of the reasons for going modular?

        Anything that helps modular synth types to stay in key’s a good thing! There’s too much atonal/dissonant/chromatic modular synth music out there. Even if you don’t buy in, what’s wrong with making chord construction easier? The qu-bit chord’s intervals are pretty basic and it hardly writes songs for you, Caligari.

        Chances are people who use these things already know between a 7th & a diminished chord is and how they’re used. Not sure about you, but I can’t imagine anyone ignorant of music theory seeing a eurorack module & thinking ‘making music is easy’.

        Also, who is this “everyone” that has multiple eurorack voices that you speak of?
