FYI, I like to use a mix of 75% smf and 25% styles. Of course, I have and will do 100% of either, but I prefer my smf. This Korg may make me shift to more styles simply because they seem to fit my song selections better.
Once I get a handle on some of these controllers I'll tackle the Songbook. It certainly seems more powerful than on the Yamahas.
I think if I give it some time, I will like the Pa900.
