macOS · Free demo + $19.99 licence
A sample organizer app that actually makes music
Most producers have thousands of samples spread across old drives, packs and project folders. Upcycle is a sample organizer app for macOS that scans those folders, analyses what is in them, and turns forgotten one-shots and loops into key- and tempo-locked song starters you can actually play.

How the sample organizer works
1. Point it at your sample folders
Select any folder or drive on your Mac. Upcycle scans and analyses everything locally, so your library never leaves your machine.
2. Hear what you already own
Instead of a list of filenames, you get playable song starters built from your own samples, matched to a unified key and tempo.
3. Re-roll until it clicks
Keep the parts you like, re-roll the ones you don't, or change key and tempo. Re-rolling is near instant.
4. Take it into your DAW
With a licence you can save sessions, export audio and drag stems straight into your DAW.
Good to know
- Does it move or rename my files?
- No. Upcycle reads your folders and analyses them in place. Nothing is uploaded and your existing library structure stays exactly as it is.
- What does it cost?
- The demo is free with no account and no time limit. A one-time $19.99 licence unlocks saving, exporting and dragging stems into your DAW, and covers up to 10 Macs.
- What do I need to run it?
- macOS 14.0 or later on an Apple Silicon Mac (M1 or newer). Intel Macs are not supported.
