I just wish that the manufacturers would either get their heads together, and decide on a COMMON MIDI spec for arranger navigation, or let the users decide their own... Most modern controllers have a 'learn' function. Something like this would be a boon for hooking two arrangers together.

You see, that is my main goal... Roland's MIDI spec is already pretty decent for general communication (although it is convoluted to control external gear from keyboard Parts but not from style or sequence - go figure!), but try to hook two arrangers together, have one play some parts of the style, have the other play the rest, and it's virtually impossible.

No two manufacturers implement style division navigation the same way, and they are ALL set in stone. I have said for a long time that, if this was easy (or even doable!) I would already have several arrangers. And I'm pretty sure so would MANY here. Shore up the weak points of your arranger (they ALL have them!) with the strong points of another... This would result in a MASSIVE increase in arranger sales, IMO.

I cannot understand why the industry doesn't see this. All it is is a tiny bit of code, and a sit down to decide the standard. And arranger sales would increase...

Maybe it's just TOO obvious?
