I managed to get that going several years ago in Squeak - 3.6 IIRC. I ran it on Windows. My focus was probably more on receiving than sending?? I was able to reach a point that notes on my piano were detected by Squeak. These things are not high priority for Pharo, but I for one would greatly enjoy seeing it work. With some digging, I might be able to put my hands on an image in which I had it working. With more digging and some luck, I might be able to find the computer side of the equation in working order. Being able to use Linux would be a plus. Good luck!
