Run Vital Synth with Flatpak.

Note: I haven't done a whole lot of testing. The synth creates sound; that was the goal for now. I haven't checked stuff like persistent data and permissions.

Grab the Debian installer from https://vital.audio/ and place it in the root of the repository. The file should be named VitalInstaller.deb, rename if necessary.

Build the flatpak:

flatpak-builder --force-clean build-dir audio.vital.Vital.yml

Now you can either run Vital directly...

flatpak-builder --run build-dir audio.vital.Vital.yml /app/usr/bin/Vital

... or install the flatpak:

flatpak-builder --force-clean --install audio.vital.Vital.yml
