Find the tempo.

Drop in a recording, review Beat Detection’s BPM candidates, and apply your chosen tempo to a compatible MIDI song.

Give every part its place.

Add pan, velocity, and reverb choices to your track-volume mix. MIDI activity meters help you follow the arrangement.

Try a new rhythm voice.

Use the Drum Instrument Picker to turn a rhythmic track into one General MIDI percussion sound.
