mcp_opendaw_explode_chords
Split chord tracks into separate voice tracks for orchestration. Distribute notes to individual instruments like bass, cello, viola, violin with configurable voice assignment and velocity balance.
Instructions
Explode chords into separate voice tracks.
Takes a chord track and splits each chord into individual voices, distributing them to separate tracks. The lowest note of each chord goes to voice 1 (bass), the next to voice 2, etc. This is the fundamental orchestration technique — converting a chord progression into individual instrumental parts.
Typical use: piano chord track → bass + cello + viola + violin. Or: synth chords → sub bass + pad + lead + pluck.
Args: unit_index: Source AU index with chord track track_index: Source note track index with chords region_index: Source region index (-1 = first region) num_voices: Number of voices to split into (2-8, default 4). Chords with fewer notes than num_voices get rests in higher voices. Chords with more notes than num_voices get extra notes merged into the highest voice. direction: Voice assignment order — "down": lowest note → voice 1 (bass), ascending voices "up": highest note → voice 1 (top), descending voices "outward": middle notes → outer voices, edge notes → inner target_units: Comma-separated AU indices for destination tracks. If empty, creates new AUs automatically. If provided, must have at least num_voices entries (e.g. "0,1,2,3"). velocity_balance: How to distribute velocity across voices — "natural": lower voices slightly louder (bass prominence) "equal": all voices same velocity "top_heavy": upper voices louder (melody prominence) "fade": velocity decreases from voice 1 to voice N
