While you're here, Steve, how about this one...
Do you honestly think a few more synth voices and a 909 kit are likely to entice younger players away from a MotifXS and pay over $1500 MORE for a T3 (street price on MotifXS6 is about $2200), without arpeggiation and loop features, or any sampling, DAW features and poorer build quality?
Somehow, I just don't think so...
But hey, if you can get the Motif team to make the loops and arps behave like arranger variations and fills (rather than the 'cue everything up in advance' way it is right now) you might get everyone here that wants a newer sound and style package and OS, but with arranger ease of control (you know, the NEXT gen customers) to go Yamaha after all!
And we wouldn't even have to bitch about the lack of a 76 or 88, either.
The chord following abilities of the XS system are SO close to being usable for us arranger fans, it would take little in OS upgrades to make them the next step, rather than having to battle the wealthy retirees that seem to be the T3's target customer.
All it would take is some extra rules about loop behavior, like dropping into a fill at any point (rather than cue it up a bar in advance) and a set of rules as to where to go AFTER the fill loop plays. Same rule would suffice for an Intro loop, and a loop that could be programmed to stop after one time through would be an ENDING.
That sure doesn't seem too hard to do (and current behavior could still be the default). On bass (bass inversions) might be the next step, but just the loop destination rules would be enough to make me jump ship from arrangers, and move into the 21st century.
Audio loops in combination with arps and styles, with a decent sampler and cutting edge as well as classic sounds is the mantra of the expensive 'open' computer based arrangers. So little needs to be added to the MotifXS to equal these in practical terms...
