mcp_opendaw_create_trill
Generate a musical trill by rapidly alternating between two notes. Specify pitches, rate, duration, accent, and starting note to create the ornament in your DAW project.
Instructions
Create a trill — rapid alternation between two notes.
A fundamental ornament used across classical (baroque trills, mordents), jazz (shake), metal (tremolo picking), and electronic (LFO-like patterns). Two notes alternate at the specified rate for the given duration. Upper note can be accented (baroque style) or both equally loud.
lower_pitch: Lower MIDI note of the trill (default 60 = C4). upper_pitch: Upper MIDI note, typically 1-2 semitones above (default 62 = D4). rate: Trill speed — "32nd", "16th", "8th", "32t" (triplet 32nd), "16t" (triplet 16th). duration_beats: Total length of the trill in beats (0.5-32, default 4 = 1 bar at 4/4). accent_upper: If true, upper note is louder (baroque style). If false, equal velocity. start_with_upper: If true, trill starts on upper note (some baroque conventions). velocity: Base velocity 0-1 (default 0.85). 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 trill begins.
Returns notes created, rate, note count.
