Quad-note chord sequencer
Expand a single 1V/oct pitch into a chord of up to 4 notes.
Program your own chords and sequence them with triggers or direct CV addressing.
The fundamental idea of Chords is to expand a single 1V/oct pitch CV into a four-note chord, with sequencer-like control over the choice of chord. This allows you to more easily arrange a song with a chord progression, adopt music theory in your patches, and create polyphonic (or arpeggiated) music.
The main circular display of Chords arranges the 12 notes of the chromatic scale in a chromatic circle.
In its initial state, all four note handles are assigned to the root note C. Click and drag a handle in a circular motion to set a note. Each full turn of 360° increases/decreases the note by 1 octave.
Click and drag the circle in the center to transpose all notes by semitones.
Each preset holds a chord, and there are 10 available presets. The chord name is displayed by the preset number, if a name is available.
Click the left/right arrows to cycle through the presets. Click the preset label to launch a dropdown menu with a list of presets, along with options “Copy”, “Paste”, and “Duplicate to all below”.
The ROOT input shifts all pitch outputs by its voltage. The note names in the chromatic circle are updated so that the top-most note specifies the root note. This also updates the displayed chord names.
The RESET input sets the preset to 1 when a trigger is received.
The ADV input advances to the next preset and cycles back to 1 after preset 10 is reached.
The ADDR input directly addresses the preset number with a scale of 1V per preset. For example, an ADDR of 0V sets preset 1, an ADDR of 1V sets preset 2, etc. When a cable is patched into ADDR, the preset selector menu and left/right arrows are disabled and overridden by the ADDR voltage.
Each output generates a 1V/oct CV signal for its corresponding note.
To take advantage of polyphonic cables in VCV Rack to avoid using four identical sound generators, select Polyphonic outputs include channels 1-N in the context menu. This causes output 2 to generate a 2-channel polyphonic voltage containing pitches 1-2, output 3 to contain pitches 1-3, and output 4 to contain all pitches 1-4. Output 1 is unchanged.
- Fix global transposition when pasting preset.
- Ignore ADV trigger up to 1ms after receiving a RESET trigger, per the VCV standard.
- Initial release.
