Add songs or four-stem folders, set BPM, and create SP-1-ready output.
JT Apps / Mac utility / SP-1
A native Mac app for preparing stem albums and transferring them to a Teenage Engineering SP-1 over USB-C.
Built for people who want the SP-1 workflow without Terminal, Homebrew, Python setup, or coding tools. Download, install, prepare, preview, and transfer.
The app download is in GitHub Releases. Download SP-1 Utility.dmg, open it, drag SP-1 Utility into Applications, then launch it from Applications.
The app bundles the local processing engine, keeps prepared tracks organized, and shows transfer status you can actually read.
Add songs or four-stem folders, set BPM, and create SP-1-ready output.
Review prepared tracks, play the preview mix, and check individual stems.
Build an album plan, watch SP-1 live controls, and transfer ready WAVs over USB-C.
Normal use does not require Terminal, Homebrew, Python setup, or coding tools. The app is built as a native Mac utility so the SP-1 workflow stays in one place.
The DMG is attached to the release instead of the Code tab because it is too large for normal GitHub repository files.
SP-1 Utility is for getting from a song or stem folder to a device-ready album without leaving the Mac app.
