I am not sure why this skepticism is so upsetting. Just SAYING it can be done without example isn't exactly proving it. I realize you perhaps feel 'invested' in your choice of equipment, and may perhaps feel uncomfortable admitting that there MIGHT be something it can't do (mind you, as admitted, no other arranger or any hardware keyboard with the exception of that expansion board can do it either, so I'm not trying to put YOUR choice down), but my goal is not to denigrate ANYTHING, merely to suggest that this capability MIGHT be useful, and perhaps spark a little interest (by all other than Donny, who never heard of anything he doesn't currently have that he might possibly use!) in the idea of it!

............You see, unlike SOME here, to me a keyboard is a MUSICAL instrument, not an 'investment' for a 'profitable return'. But hey, if that's all anyone thinks about the thing they pour their heart and soul into (or not!), perhaps staying out of discussions where musical improvements are talked about, and stick to discussions of paid gigs, booking strategies, and contract disputes might be better!

If this ever gets added to an arranger you end up using, and you actually LIKE the sound, you can thank me later!
