stemdeckapp/stemdeck

> [!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

Optional: fresh-install cleanup. To reproduce a true first-run with no leftover state from earlier builds, open each path in Finder via the Go menu, then Go to Folder (Shift+Cmd+G), and move the folders to Trash:

• ~/Library/Application Support/StemDeck
• ~/Library/WebKit/app.stemdeck.desktop
• ~/Library/Caches/stemdeck
• ~/Library/Caches/app.stemdeck.desktop

You can also delete ~/Library/Preferences/app.stemdeck.desktop.plist the same way. This is optional; the app will work without it.

What's new in 0.7.0 Alpha 6

Reliability

• Fixed the waveform being offset from the playhead and the audio. The stem lanes were drawn a fixed 48px to the right of the ruler, so t=0 in the audio landed before the waveform visually began. The gap was constant in pixels, so it read as a different number of seconds per track (longer songs showed a bigger gap) and stayed put when you moved the marker. The overview layer now starts exactly at the ruler's 0:00, so the playhead, what you hear, and the waveform line up. (#189)
• Restored the bar-style waveform. With the audio engine driving playback, the lanes had switched to a filled envelope shape. They now render as discrete bars again (matching the rest of the studio), with silent sections shown as a faint baseline. (#189)

Installing

• macOS: drop the .app into Applications and launch (run the xattr command above first).
• Windows: unzip the downloaded .zip, then run StemDeck.exe from the extracted folder.

Artifact build

• macOS arm64 and x64 DMGs and runtime packs were built and inspected on a macOS Woodpecker agent before upload.

Artifact scan

• Windows portable packages were scanned with ClamAV in CI before upload.
