ChordBud 2 is a MIDI chord sequencer for building unique chord progressions in minutes. Under the hood is a powerful music theory engine with over 40 scales. Select the scales to work with and see them laid out top to bottom on one screen, with the chords inside each scale running left to right, compare scales side by side, or borrow chords from one another through modal interchange. By default, every chord inside the current scale and key is presented at once, and the key can be changed anytime. The settings menu also offers chord progressions to work within, showing only the chords that belong to the selected progression. Build as many patterns as needed, each with its own key, scale, and chord progression. Long-press a pattern to copy, paste, or delete it, with full undo/redo backing every edit so experimentation stays risk-free. Patterns can be triggered via MIDI CC messages, enabling automation or a full song mode. Triads are just the starting point - chords can be extended with add/sus/6/7/9/11/13 and more modifiers. Tap any chord on the timeline to open the chord editor and adjust its mode, velocity, octave, inversion, key, or division. Edits apply live while the sequencer plays, so changes are audible immediately. On the timeline, chords can be repositioned by dragging, or resized by dragging their right edge. Pinch to zoom in or out, or zoom in further to work precisely within subdivisions. Standalone, ChordBud 2 includes a built-in piano sampler for instant playback with zero setup, alongside MIDI, virtual MIDI, and Bluetooth MIDI connectivity for hardware and software instruments. An AUv3 plugin version is also available, dropping straight into any DAW to drive instrument tracks from inside a session. Note: ChordBud 2 AUv3 plugin is a MIDI sequencer app. It does not produce sound itself. You need an audio app in order to get sound. Just route ChordBud 2's MIDI Out to your audio app's MIDI in and arm the sequencer.
