I will add another super annoying little thing; jam track volumes are all over the place. Some of them are okay, some super loud (easy to fix with a slider) but many of them are just too quiet making it hard to practice to/ - not really fixable on the users' end. You just have to play quieter to match the low volume of the jam track...
