I wanted to share with you my recent instrument, the Space Regenerator. https://www.youtube.com/watch?v=2hObtEY1NTk
It is made with Rasp Pi 2, Arduino, HiFiBerry Amp + and an old microscope case. The audio programming is done with ChucK.
I really enjoyed working with the Amp+!
The instrument and music were made as a part of the Instruments INDIA commission by Liverpool Hope University and Milapfest.
You can download the accompanying album (and loop the compositions yourself) at this site: https://gregdixon.bandcamp.com/album/anantat-navaj-vana
