SimPlay listens to every track and sorts it by energy, genre and Camelot key — 100% on your machine. The more you use it, the better it gets you: it adapts to your ear and gets your sets ready for Rekordbox.
Tags lie. Genres are inconsistent. And the one thing that actually makes a set work — energy — is invisible until you've listened to every track twice.
SimPlay rates every track Low, Mid or High — the same instinct you use to read a floor, applied to your whole library in minutes. Build the rise, land the peak, cool it down. On purpose, every time.
Every song you play helps SimPlay understand you a little better. It picks up what you choose, what you skip, the energy you're after and how you organize your music. Over time it stops being just another player and becomes one that truly adapts to you.
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. Your library becomes searchable by feel.
The Camelot wheel lights up compatible keys, so every transition lands in tune.
Every track filed on disk by genre and energy — the same clean structure mirrored to your cloud. Point Rekordbox at it and go.
Your audio backs up to your own Google Drive or Dropbox — never our servers. Live storage meters show exactly how much room is left.
The more you use it, the better it gets you. SimPlay picks up how you listen — what you choose, the energy you're after — and sorts your music the way you would. Your taste follows you, synced across your devices.
Send smart playlists to Rekordbox as .m3u8, grouped by energy and genre, ready to play.
Drop in your tracks. SimPlay decodes the audio itself — it doesn't trust existing tags.
Energy, genre and key, 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.
Every bit of analysis runs on your computer. Your unreleased edits and IDs never touch our servers — backups go to your own Google Drive or Dropbox. The only thing that syncs is a tiny model of your taste.
