Motif Lab — evolve your melody
Drop a .mid file — a short motif, a theme, or a whole melody. The app reads its key, tempo, time signature and range, then produces several variations through mutation strategies. Each one downloads as its own .mid. Turn a variation into a full track (prompt + multi-role MIDI) or optional chords/bass only.

Syllables set the rhythm, letters become notes (a→A, b→B, c→C…), the first syllable of each word is stressed. The same phrase always gives the same melody.

Journey Planner — mix set with harmonic flow
Plans a sequence of tracks: the Camelot Wheel holds the harmony together, an energy curve drives BPM and genre choice, and bridges appear between genres that sit far apart. Every track gets a finished Suno prompt.
