The Invert dial and chord-shaping controls on the Chord Chameleon faceplate.

Play the shapes you already know

Keep playing familiar chord shapes while Chord Chameleon moves them into new inversions and voicings.

Preselect the next change

Choose a new inversion or voicing while the current chord is still held. The change takes effect on the next struck chord.

Keep the bass and melody intact

Chord transformations stay focused on the chord, leaving bass and melody notes outside it where you played them.

Rework existing MIDI parts during playback.

01

Give a repeating progression changing inversions

Play or loop a progression and let Auto Invert vary its inversions. Choose a directional or random pattern, limit its range, and control how often changes occur.

02

Remix MIDI clips while they play

Loop an existing MIDI part and try different inversions, voicings, octave settings, and rhythmic patterns during playback. Hear alternate versions without redrawing the notes for each idea.

03

Revoice chords without rewriting the bassline

Explore different inversions and voicings while bass and melody notes outside the detected chord retain their pitches. Adjust the chord octave separately when you want a different register.

04

Build continuing patterns from short notes

Use Chord Latch or Bass Latch to keep a pattern running after its input notes end. Turn short notes in an existing MIDI clip into longer-running rhythmic parts.

05

Create cross-rhythms from chords and bass

Give the chord and bass patterns different loop lengths while keeping both synced to tempo. Change the interaction between the two parts without changing the underlying notes.

06

Start with a preset, then reshape the groove

Load coordinated chord and bass settings, play both parts, and adjust the result. Change the grids, loop ranges, rates, note lengths, and Swing to develop the pattern further.
