BeagleBone's PRUs are an enabler of Bela, "the embedded platform for ultra-low latency audio and sensor processing" which was ~1000% funded on KickStarter earlier this year.
Bela is being used at the Augmented (Musical) Instruments Lab in London (and now the community) to make rich, responsive digital musical instruments. It has a Web IDE, supports C++, Pure Data, Faust, SuperCollider, etc., but again thanks to the BB's PRU's, it supports audio-rate sensor sampling!
What a beautiful project. I started to hack around for a guitar amp emulator on the bb in 2014, but it quickly became too involved. Thanks for sharing.
