Using JustChords as an Audio Unit Plugin

JustChords operates as an AUv3 MIDI plugin in DAWs like Loopy Pro and AUM, sending block chords and control messages synchronized to the transport. It features two independent MIDI outputs (MIDI 1 and MIDI 2) for flexible routing to instruments, samplers, or other plugins.[user-provided] Users commonly integrate it for live chord triggering, section changes, and song progression in looping and modular workflows.

MIDI Output Configuration

JustChords provides two configurable MIDI outputs: MIDI 1 and MIDI 2.

Each output supports these modes:

• Off: No MIDI transmission.
• MIDI Chords: Sends standard MIDI note block chords on transport beats.
• TonePacketProtocol Chords: Proprietary chord format for compatible apps/devices.

For Chords mode:

• Set anticipation (lead-in) to allow downstream apps processing time: 1/4 beat, 1/8 beat, or 1/16 beat.[user-provided]
• Chords fire in sync with DAW transport

Additionally:

• MIDI on song appear: Sends a custom MIDI message when a new song is displayed/loaded. You can define message in SongEditor.
• MIDI in SongStructure definition - IN_PROGRESS
• Control Messages: Transmits CC messages on section changes.
  • First section: CC with value 1
  • Second section: CC with value 2
  • Etc.
  • End of last section: CC with value 0
  • Full spec: MIDI CONTROL port transmits CC when entering new sections (1, 2, etc.); value 0 at song end.
