This is a quick post to let people know that this project is still alive. I had to put development to one side for a few weeks so that I could a) earn some money, and b) build a big shed in my garden so I've got somewhere better to work in the future.
However, I can report that the audio code is working better than before, with a couple of exciting new features, and MIDI in/out seems to be working nicely too.
I may have missed my wildly optimistic deadline of a November 2019 release, but at least now I've missed it by so much that I'm free of its (silly, self-imposed) pressure ;)
Excited to show off the "final" version here when it's done...
