mcp_opendaw_create_soli
Generate a soli: ensemble unison melody doubled across octaves. Specify melody/rhythm patterns, key, scale, and voices to produce a homorhythmic passage on multiple tracks.
Instructions
Create a soli — ensemble unison passage with octave doublings.
A soli is a section where all instruments play the same melodic line in rhythmic unison, typically at different octaves. Common in jazz big band (Basie, Ellington, Herman), orchestral tutti passages, and rock/metal unison riffs. Unlike a fugue (polyphonic imitation) or canon (delayed entry), a soli is simultaneous and homorhythmic.
Melody pattern: space-separated scale degrees (0=root, 2=2nd, 4=3rd, -1=7th below, etc.). Negative = below root. Rhythm pattern: space-separated durations in beats. Key root: C, C#, Db, D, ... B. Scale: major, minor, dorian, phrygian, lydian, mixolydian, aeolian, locrian, harmonic_minor, melodic_minor, pentatonic_major, pentatonic_minor, blues, whole_tone. Voices: 2-5 (e.g. 3 = root octave + 1 octave up + 2 octaves up). Octave spread: how many octaves between lowest and highest voice.
Creates voices on track_index, track_index+1, ... track_index+voices-1.
