I'm looking into the styles right now ... trying to thin them out.
There's a few more cool things I found -

1. The manual bass button instantly disengages the auto bassist, and maxes the volume limit to the bass tone in the pattern. You can pick it up live for those hard to "feel" riffs that just HAVE to be right. When you're done - just hit the chord recognition button again. It's a snap!

2. You can asign a button to mute all 5 accomanament parts at once, creating a bass&drums only backing. LOVE this feature.
