ChordBud 2 AUv3 MIDI Sequencer
A MIDI chord sequencer with scale comparison, editable patterns, chord modifiers and standalone or AUv3 workflows.
Consider for musicians exploring harmonic sequences
Patterns can keep separate keys and scales, allowing experiments with borrowed chords and sequenced changes.
Keep in mind: The standalone description mentions a piano sampler, while the AUv3 plugin is explicitly MIDI-only and needs an instrument for sound. Host compatibility and routing require checking.
