has anybody noticed the difference in the drum sounds since the last update. I played through a few of my chord charts and noticed a few other difference in the Baseline on chords with alternate bass notes. also i noticed the way the baselines played in general were different. I'm going to play through a few more of the chord charts I'm used to and look for other differences. Let me be clear, I'm not happy with the drums. Is there a way to roll back to update to previous drum patterns, fills and sounds.
