Audio Tools and Sound Libraries

a pretty good multi-platform audio resource is JUCE. I can install it (it has its own development environment), but we'd probably need a license. JUCE would give AUMI Together a little more than cross platform native support: also be available as an audio plugi, for instance.

Compose from JetBrains: (via Phil Burk) https://www.jetbrains.com/lp/compose-mpp/ Kind of multiplatform, but not iOS and not Plug-innable. Not really music oriented.

Capacitor! https://github.com/ionic-team/capacitor might actually be what I need.
