Every time you run AI Compose, MIDY generates three different takes of your idea from the same single credit. They appear as A, B and C above the piano roll: tap to compare them, play each one, and download the one you like best. It means a credit buys you a result you're happy with, not just one attempt.

A quick guide: Trap / Drill, try “Dark” or “Hypnotic” at 70-90 BPM. Lo-fi / R&B, “Chill” with Piano Comp. EDM / Techno, “Hypnotic” or “Epic” in Arpeggio mode at 120-140 BPM. Cinematic, “Epic” for heroic themes, “Dark” for tension, “Dreamy” for ambient. Pop / Indie, “Happy” or “Dreamy”.
Melody generates a human-like melodic line using phrase-based logic that fits the mood's chords. Piano Comp generates both chords and melodic fills together, like a session pianist. Arpeggio plays the notes of each chord in a repeating pattern, great for synth lines, bass and rhythmic backgrounds.
The in-browser preview uses a lightweight synthesizer (Tone.js) so the page loads instantly on any device, and each mood has its own synth character. The MIDI file you download is pure note data, load it into your DAW and assign any instrument or VST you want: piano, guitar, strings, anything.
A MIDI file isn't audio, it's data, like sheet music for computers. It tells your DAW what notes to play, when, and how hard. That gives you 100% control: change the key, edit notes, adjust tempo and swap instruments freely.
The piano roll is the visual grid that appears after every generation. It shows melody notes and chord notes on a time-vs-pitch grid, and during playback a playhead moves across it so you can see each note as it sounds.
