Chord 4 Voice Polyphonic Oscillator - 28HP

Qu-Bit Electronix Chord

The Qu-Bit Electronix Chord is a four-voice polyphonic oscillator for use in Eurorack modular synthesizer systems. As its name suggests, the Chord makes it extremely easy to create chords without the time usually required to tune oscillators. Additionally, the module can generate chords using harmonic motion, allowing for the effortless creation of meaningful progressions based on an external signal. A dedicated Harmonize button selects a corresponding chord voicing as dictated by a particular root note, resulting in harmonic motion. The module boasts individual outputs for the root, 3rd, 5th, 7th, and a mix of all four. The nearby Triad button drops the 7th note from the chord. 

The Chord features overlapping, fading, morphable waveforms that result in unique timbral shifts. Powerful voicing control determines how the chord is configured across the selected octave, while the Root control alternates the lowest note in the chord. There’s also a Quality control that changes the type of chord from major 7th, minor 7th, dominant 7th, and even half diminished chords. 

Chord Features

  • 4 voice polyphony with individual and mixed outputs (root, 3rd, 5th, 7th)
  • Auto harmonization with a bass line option
  • Triad chord button
  • Variable wave shape (sine, triangle, saw, square)
  • Adjustable chord voicing (spread, drop 3, drop 2, close)
  • Adjustable chord inversion (third, second, first, root)
  • Adjustable chord quality (half diminished, dominant 7th, minor 7th, major 7th)

Qu-Bit Chord Demo

The beginning sound sample is demonstrating the waveshape morph of the Qu-Bit Chord. The Mix out provides all the notes in the chord, with the Triad button removing the 7th. The voicing and inversion knobs are great for performance, providing useful re-harmonizations of chords. When a sequence (from Intellijel's Metropolis) is patched into 1v/Oct, the Harmonize button was also pressed, to provide harmonic motion based off of the root note. A second sequencer (Verbos' Sequence Selector) was then patched into the Voicing control, and a Sample and Hold output (from Verbos' Random Sampling) is patched into the Inversion control to provide stepped modulation in tempo with the chord changes. The Mix output is being fed into one channel of Streams, from Mutable Instruments, in the Vactrol modeling mode, which provides the slight grit and percussive character.

Qu-Bit Rhythm Wave Chord and Contour from Perfect Circuit Audio on Vimeo.

Triggering the Qu-Bit Wave sampler with the Qu-Bit Rhythm for drums, the Qu-Bit Chord adds chords over the drums. The Varigate 8 is being used for extra cv to movie around the pitch on the wave sampler. All of the audio is being put thru the Intellijel Linix and being gated by maths and Qu-Bit Contour quad envelope. Some compression is added by the WMD MSCL stereo compressor.
