A web app to feather notes played over any and all MIDI inputs, outputting to a device of your choice, and to try React and Jotai.
Similar to the Seldon Black software Bear McCreary used for the Foundation soundtrack, though developed independently and originally producing notes via L-systems. I do not watch a lot of television, and loved the Asmiov books when I read them 40-odd years ago, so it took me a while to even hear of the Foundation series, let alone watch it. Must do better.

For a minimal setup, try midiLoop.
GitHub Actions does not support a Bun lockfile, so an NPM lockfile is included. Ugh.
A small application using Vite, React, Jotai, Web MIDI, mainly to compare React/Jotai to Vue3/Pinia.
Were I to program this again I would use SolidJS - both much faster and more readable.
Support sustain pedal?
Touch a lamp above/below each range slider to toggle MIDI learn for that end of the range slider.

That is, to link a controller to the end of a range, click to ilght a lamp and enter 'MIDI Learn' mode, then activate a controller to assign it. To deactive, click the same lamp again. To reactivate or relearn, click the lamp again.
