Just a quick update - a couple of weeks ago I passed my PhD viva, with minor corrections. I was absolutely delighted with how it went, and really enjoyed getting to discuss my work with two extremely insightful examiners. It's a nice conclusion to a jam-packed few years, where I've learned an enormous amount both about music and about many other subjects.
I've made a fairly eclectic set of stuff in recent years, from apps to hardware projects. Check out the list here.
