I’m convinced that playNote doesn’t work as it should. My firmware is reported as being up to date but even the demo program “MusicalNoteTests.c” doesn’t work as it theoretically should. I have slowed it down and listened to it over and over again, and it seems to me that the “octave” parameter makes little or no difference, and the sharps don’t appear to work. I think out of a theoretical 36 different notes, it’s only possible to get about 8. I have tried using “playRaw” but so far haven’t managed to string more than a couple of notes together. I can’t find and info on using this - any tips?
