Swing rolls at 142 BPM with the triplet feel baked into every lane — ride pattern, comping and melody all lean on the swung eighth.
Swing is included with the Pro and Studio plans; the free plan covers five genres. See pricing.
How the engine writes swing
The bass walks, the chords stab in section-style riffs, and the single melody line phrases like a soloist over the top. Point the MIDI at a big-band library and the bones are already right.
From a roll to your DAW
A roll defaults to 142 BPM (every preset and tempo is editable before and after generating) and plays back in the browser through the studio's own synths. When you like a take, export it as whole-track or per-instrument MIDI, or as WAV/MP3 audio — the drum part uses General MIDI numbering, so it lands correctly on any drum plugin. There are step-by-step import guides for Ableton Live, FL Studio and Logic Pro.
