Incubator project for audio/midi processing code. This is currently partly hard-coded to my setup (mixer, analog synths, midi controllers, a delta1010 and Pure Data + custom jack audio modules).
This project consists of:
a jack-based "data plane" for low-latency audio and midi, and
an Erlang-based "control plane" for user interface, network and storage interfacing
I've really enjoyed using Erlang in my payed work on data acquisition system control plane code in these last couple of years, so I started to apply the approach to the midi & audio world as well.
Additionally, I've gotten into development tools again, working on "fast cycle development" which is incorporated in my (closed source) exo project. I've really enjoyed using Erlang in this setup. Its flexible code reload features work well for millisecond-level edit-and-test cycle. It's a great framework for applying the same approach to C and Rust code development.
