Don,

Is it easy to set up a series of sounds and a style quickly, as in an unexpected request for a tune using instruments you don't often use?

i.e. on the Tyros4 or PSR you can temporarily change the style's four OTS sounds without storing the style. Not lightning fast, but quick nonetheless.

Even if you only have to change one sound, it's still pretty convenient.

When you reload or change the style the OTS returns to what was there previously.

What features of the BK-9 make it a keeper, if you could find workarounds for the problems?
