0.7.0 Alpha 18
Important
macOS first launch (no code signing yet). After dragging StemDeck to Applications, clear the Gatekeeper quarantine flag or macOS will say the app is damaged:
xattr -dr com.apple.quarantine /Applications/StemDeck.app
Upgrading from alpha.9 or earlier? If after installing you still see an old version or are missing recent features, clear the cached runtime once and relaunch:
rm -rf ~/Library/Application\ Support/StemDeck/runtime ~/Library/Application\ Support/StemDeck/runtime.old
What's new in 0.7.0 Alpha 18
Export as MP4 (new)
- Export your mix as a video. Mute the vocals (or any stems) and export an MP4 that pairs your custom mix with the original picture. (#219)
- Imported
.mp4files keep their original video, muxed losslessly with your mix. - YouTube imports download the real video stream (H.264, up to 720p) and mux it with your mix.
- Pick MP4 from the export format toggle (WAV / MP3 / FLAC / MP4), then Export Mix. The MP4 option appears only for sources that have video — SoundCloud and plain audio files stay audio-only.
- Imported
Linux: FFmpeg now installs automatically
- On Linux, StemDeck now downloads FFmpeg on first launch (matching Windows and macOS) instead of requiring
sudo apt install ffmpeg. A systemffmpegon your PATH is still used if present.
Fixes
- Your library no longer disappears. The desktop app no longer applies the 24-hour job cleanup to your personal library — your tracks persist until you delete them yourself (via Trash). Previously, reopening the app a day later (e.g. after installing an update) could purge a track's audio while leaving its library entry behind.
Other
- "Supporters" is now We Recommend, with new picks (Thomann, Analog4Lyfe, Empress Effects). (#228, #230)
Installing
- macOS: drop the
.appinto Applications and launch (run thexattrcommand above first). - Windows: unzip the downloaded
.zip, then runStemDeck.exefrom the extracted folder. - Linux: download the
.tar.gzfor your hardware, extract it, and run./StemDeck. Install the WebKitGTK + GTK runtime prerequisites first (FFmpeg is fetched automatically on first launch):The NVIDIA build additionally needs a working NVIDIA driver such thatsudo apt install libwebkit2gtk-4.1-0 libgtk-3-0nvidia-smireports your GPU (the CUDA runtime itself is bundled — no separate CUDA toolkit install needed). If you have no NVIDIA GPU, use the CPU-only tarball.
