This is the final part of the MIDI Guitar and Trill touch sensor projects. Published in The Mag Pi number 105, May 2021. Here we see how the Trill touch Guitar modes operate, and how it can be played. Apologies in advance for my "singing", try and imagine someone good doing it. My version of House of the Rising Sun got flagged by someone claiming they had copyright on the melody. They dropped this claim when I pointed out it was a "traditional" song and you can't have copyright on a traditional song. The pub called the Rising Sun is situated on the A6 south of Stockport where the Macclesfield road splits off the A6. It has been called that since the 1950's to my knowledge, probably much longer.
