mcp_opendaw_create_riser
Create ascending pitch sweep risers for build-ups and transitions. Generates note sequences with ramping velocity to build tension before drops or choruses.
Instructions
Create a riser — ascending pitch sweep for build-up transitions.
Generates a sequence of notes with ascending pitch from start_pitch to end_pitch over the specified length. Velocity ramps up proportionally. Useful for:
Build-ups before a drop/chorus
Transition between sections
Tension creation
unit_index: AU index with note track (-1 = find first AU with note tracks). track_index: Note track index within the AU. start_beat: Position in beats where the riser begins. length_beats: Duration of the riser in beats (1-16). start_pitch: Starting MIDI pitch (default 36 = C2). end_pitch: Ending MIDI pitch (default 84 = C6). steps: Number of notes in the sweep (8-128, default 32 = sixteenths over 4 beats). curve: Pitch curve — "linear" (even), "exp" (slow start, fast end), "log" (fast start, slow end). velocity: Base velocity (0-1, ramped proportionally with pitch).
Returns notes created and pitch range.
