Esh,
I don't have a 9000 Pro, and I don't use an external sequencer, so can't help. I will try to help anyone when I think I have something to contribute.
I must agree with you about Yamaha's lack of support. I plan to change brands. However, I don't blame you or the others on this forum for that. And I have been very vocal about Yamaha's hypeing the Tyros many months in advance.
As to the off-topic discussions, you can read them or not. If it bothers you so much that it is a problem for you, then aim your browser in a different direction. There are quite a few discussion groups that I don't go to because of the constant bickering and use of inappropriate language. You don't find much of that here.
Go in peace, or stay in peace, it's up to you.
