Hi,
This may be slightly off topic but basically I like to strip styles when they are too busy of the obvious sounds and in particular I like to cut down on the drums which as you all know Korg does do a lot better than Yamaha. Talking of which and no doubt Gary, Don,Donny etc. could confirm this or help me out here: If you want to change instruments in the styles ,which I often do, I find that the PSR750 does not allow for instance to replace the five acc. sections ALL by piano. You can replace a piano acc. track by another piano but if the track has brass or whatever you cannot replace it by piano. And the section STYLE Voices is a laugh. It does not even include piano. I mention piano as an example mind you. ( though I have often found that with Roland and Korg styles, if you replace all acc.tracks with dry acoustic piano, you often get very laudable results !)
regards
John
