Chords

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.

Chords Manual

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.

Chromatic Circle

The main circular display of Chords arranges the 12 notes of the chromatic scale in a chromatic circle. Chords constellation

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.

Chords

You can store an unlimited number of chords with VCV Chords. Click the chord label to open a menu with options to add, duplicate, cut, copy, paste, and delete a chord. When more than one chord is added, click the left/right arrows to cycle through the chords, wrapping around at the end.

If a common name of the current chord is available (such as “C major”), it is displayed next to the chord number.

Inputs

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 chord number to 1 when a trigger is received.

The ADV input advances to the next chord and cycles back to 1 after the last chord is reached.

The ADDR input directly sets the current chord by a voltage, scaled from 0V to 10V. For example, if your chord sequence has 8 chords, an ADDR voltage of 0V sets chord 1, 10/8V (1.25V) sets chord 2, 20/8V (2.5V) sets chord 3, etc. and 7*10/8V (8.75V) sets chord 8. Voltages outside this range wrap around cyclically. When a cable is patched into ADDR, the chord selector menu and left/right arrows are disabled and overridden by the ADDR voltage.

Outputs

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.
