Hello! I'm SolarLune, a wannabe indie game developer and musician, and I've been making video tutorials for the free (on most platforms) cross-platform tracker, SunVox, for quite some times now. The quality varies between videos, unfortunately, so sorry about that.
I currently have around 15 parts up on my YouTube channel. They're really basic, and not even really 'tutorials' so much as just videos showing basic usage of some of the modules and techniques I use in SunVox. They're really amateur-ish, I know, with a lot of "umms" and "aahs", but I'm just doing it for fun, basically.
