SimPlay classifies every track by energy, genre and Camelot key — right on your machine — and builds harmonic sets ready to export to Rekordbox. The more you use it, the better it knows your sound.
SimPlay listens to the audio — not just the tags — so your whole library becomes searchable by feel, genre and key.
Every track auto-tagged Low / Mid / High energy, by genre, and by Camelot key. No more manual crate-digging.
An interactive Camelot wheel lights up the compatible keys, so every transition lands in tune.
Send smart playlists straight to Rekordbox as .m3u8 — grouped by energy and genre, ready to play.
Correct a call once and SimPlay adapts. Your personal model syncs to the cloud and follows you across devices.
All audio analysis runs on your computer. Your music never gets uploaded — we only sync the tiny model.
A global player to re-tag while you listen, a photo-grid library browser, and ⌘K to jump anywhere instantly.
Add your tracks or read them in place. SimPlay decodes the audio itself — it doesn't rely on existing tags.
Energy, genre and Camelot key are detected in the background while you keep working. Unsure calls go to a quick review queue.
Filter by energy or key, build harmonically-compatible playlists, and export straight to Rekordbox.
