I try out the tec breath and bite controller on Dmitry Sches's Thorn CM synth in a chill/ambient MIDI Guitar piece. https://youtu.be/l7odPRhDoMA. Geek details at Way Music. Want just the music? It is on BandCamp. The instant feedback of controlling through the breath is strikingly intuitive, so I could bring things to the edge but back off before they spilled over into mayhem.
