THE CHORD BROWSER PANEL
The Chord Browser is a collapsible panel on the right side of the piano roll (and the notation view) for browsing, auditioning, and placing chords.
KEY PREVIEW GRID
The top of the panel shows a clickable grid of all the diatonic chords in the current key and scale. Click a chord to audition it through the track's instrument; double-click to insert it into the chord lane at the play indicator.
PALETTES
The Palette dropdown selects the working set of chords:
Basic — Triads, Power chords, Sus chords
Extended — Dom7, Maj7, Min7, Add9, Diminished, Augmented, and more
Genre — Blues, Jazz, Gospel voicings
Custom — your own palettes (see Custom Chord Palettes and Styles)
STYLES
The Style dropdown chooses how chords play back: 116 curated styles across 32 genre categories including Acoustic, Ambient, Arpeggio, Bass, Blues, Classical, Country, EDM, Funk, Gospel, Jazz, Latin, Metal, Orchestral, Rock, and Synth. Styles range from arpeggios and strums to pads and full rhythmic patterns. A "cyclical" icon next to a style name marks styles that repeat in a loop, as opposed to one-shot styles that play once per chord press.
Below the style dropdown, dynamic parameter controls appear for the selected style — Gate, Swing, Voice Leading, Velocity, and other style-specific settings.
PLACING CHORDS
Drag any chord from the browser directly onto the chord lane (or onto the staff in notation view). The Octave spinner controls the preview and placement octave. Placed chords use your last-used duration.
