This is a fork of the sched_ext scheduler repo with experimental support for MIDI. The idea is to be able to interact with schedulers via MIDI to observer and adjust the runtime properties of a scheduler. To interface with MIDI the schedulers use the midir crate.
I don't have a lot of MIDI devices, so I picked up a APC Key 25 for ~$100 USD. I chose this device because the MIDI interface was rather well documented and it had decent reviews. I'm by no means a DJ or music maker so everything is just for fun. The device has a nice RBG LED pad and 360 rotary encoders. I plan on adding support for tuning scheduling domains via the RGB matrix and rotary encoders.

In the past I experimented with generating audio via bpf.
