I'm happy to share a rewrite of my old MIDI synthesizer from C to RPython: https://github.com/rpypkgs/dioxide This rewrite is 43% of the old code, fitting into a single module. Like the previous version, it is suitable for realtime performance.

I haven't recorded a demo video, and I haven't confirmed that performance is acceptable on aarch64. I also haven't added a JIT driver, because -O2 was sufficient in testing.

But the year's almost over, so. Also, I had to write JACK bindings: https://github.com/rpypkgs/dioxide/blob/master/jack.py Just like with the libuv bindings I wrote before, I'm happy to put this into a standalone repository with MIT licensing; just ask.
