I know what you mean....I got some of those genre-specific soundpacks and that helped a bit. They are only used for some of the games though....

Sound library has been expanded since I've been a member but practicing with specific instruments is really helpful for me and I haven't grown tired just yet since I'm more concerned with listening for details rather than the performance. Keep practicing and let's hope we can see more updates/expansions from the Soundgym team in the future. ;)

@Craig Sheffield Good point. I usually select the same instrument for a particular game. I'll often avoid some because they can be distracting.
