mcp_opendaw_create_section_transition
Combine filter sweeps, volume fades, mute automation, and impacts into a single coordinated transition from one section to another, replacing multiple individual calls.
Instructions
Create a complete section transition in one call — combines multiple automation tools.
The most common arrangement technique: moving from one section to another (verse→chorus, breakdown→drop, intro→main). Each preset combines filter sweeps, volume fades, mute automation, and impacts into a single coordinated transition. Replaces 3-5 individual calls.
transition_type: One of: "drop" — Breakdown→drop: filter close on synths, drums muted, then filter open + unmute + impact "buildup" — Verse→chorus: filter open on lead, volume fade in on pads, snare roll implied "breakdown" — Main→breakdown: filter close on drums, volume fade out on bass, mute synths "intro" — Silence→intro: volume fade in on all, filter open on pads "outro" — Main→outro: volume fade out on all, filter close on lead start_beat: Transition start position in beats. duration_beats: Total transition length in beats (default 16 = 4 bars). unit_indices: Comma-separated AU indices. Convention: drums=0, bass=1, lead/synth=2, pads=3. Adjust to match your arrangement. Default "0,1,2,3".
Returns summary of all automation created across units.
Examples: create_section_transition("drop", start_beat=32, duration_beats=16) → 32-48: filter close on synth, drums muted at 32, filter open at 44, unmute+impact at 48 create_section_transition("intro", start_beat=0, duration_beats=8) → 0-8: volume fade in on all, filter open on pads
