Nice, I just installed this on a Raspberry Pi 3 with a touch screen I had around. Save for an issue when installing rtaudio (requires libasound2-dev in Debian), it went almost flawlessly. I'm guessing the RPi 3 can't handle realtime audio and graphics, as popping was frequent (although not annoying for the purposes of experimenting). The buttons did nothing, I'm afraid, but the web interface is ace!

I'd love to write about this soon. Kudos to the coder
