OK, So I have been spending time with the SX900.
When I change to a different style part (A-B ect) AND I hold the RH not(s) I get a bad change over to the new sound right away. In other words the SX does NOT wait until I release all RH notes before changing sounds. Sometimes it results in a very bad sound and not even the next OTS , just a loud sounds of the one I was on.

I have looked in the menu system for an option on this and didn't find one....that is to wait until ALL RH notes are released before changinging the sounds.

This can't be right...how would you hold a not that is TIED into the next measure , but change the rhythm on the downbeat??

This is pretty basic....
Thanks for any help/suggestions.
