mcp_opendaw_create_turn
Create a four-note baroque turn ornament (gruppetto) around a main note, choosing upper or lower direction and interval. Adds circular motion to sustained notes in MIDI compositions.
Instructions
Create a turn — circular ornament: main → neighbor → main → other neighbor → main.
The turn (gruppetto) is one of the four essential baroque ornaments (trill, mordent, turn, appoggiatura). It circles around the main note in a four-note flourish. An upper turn goes up first (main → upper → main → lower → main), a lower turn goes down first (main → lower → main → upper → main).
Think Mozart piano concertos, Beethoven sonatas, Bach partitas. The turn adds elegance and circular motion to a sustained note.
main_pitch: The primary MIDI note (default 60 = C4). direction: "upper" (main→up→main→down→main) or "lower" (main→down→main→up→main). interval: Semitones to neighbors (default 2 = whole step). 1 = half step (diatonic). duration_beats: Total length in beats (0.5-4, default 1.0 = quarter note). 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 turn begins.
Returns notes created, pitches used.
