I cautiously installed it (had so many disasters this year that I was genuinely afraid this would be yet another) and it went in without any issues.
In playing with it last night, I am pleased to report that the problem of the key change when playing a chord sequence and hitting one of the End buttons has been fixed! No more jumping to Cmaj on outros. It works as I always thought it should.
Noticed a couple new styles that sound pretty good. More colorful icons. And that KAOSS thing I have to find out what that does. Seems to affect the players, rather than the keyboard, but I'm just poking at it.
Overall, not bad. But I would have loved to see many more modern Jazz styles and some styles that are similar to Japanese modern music styles. Still waiting for someone to make such a library.
