hi, here's a copy of the email I received from DonM. Don, I hope you don't mind me posting it here because it contains a valuable hint (especially for us PSR newbies) about how to easily access 'style part' instrument changes from the STYLE 'channel on/off' display, which can be setup to appear in the MAIN menu. AMAZING!

"Yes, the 9000 requires going to a submenu to change voices. It is actually
easier to do on the 2000. I'm sure you know that on the 2000, that while in
the style part on/off display, you merely push the top of the button to
display the voice changes for that part.
Individual style part VOLUMES are easier to reach on the 9000. It is just
one "click" away at the most."
