I reasoned that, seeing as SonicPi was a Ruby-derived language, that SonicPi should therefore be able to control the UnicornHAT. Within the hour, I was tweeted by Wayne Keenan who had managed to do it using a Python server, sockets and a lot of know-how. Here is the result:

Wayne has put all the code and some instructions up on GitHub – so head over there now to see how he did it.
