James, sorry I don't think I made it clear.
I do agree the PA will have ALL the B+B sounds, but what I was trying to say was that if you want styles to be played using MORE than just the bread and butter sounds on the PA2 (or 1), then sending the data to a Motif XS and using some of the great sounds on the XS makes a huge difference.
As for the new toys, I tend to look at it a bit differently. I think a user needs a good grounding in loops and loop/sample technology AND PC's/Macs to even get something half decent out of them. And then the ability to put it all together into something musical.
Mind you having said that, I am not too au faix with all the current crop of audio loop and sample gear, so I could be wrong in that view.
I have no doubt that YOU could do this with ease, and I daresay using just those tools, would have a song up and running in minutes, but that expertise has taken you a few years to acquire, yes?
The arranger, o.t.o.h. CAN (although shouldn't be, imho), be set off with just one finger, O.O.T.B.
I DO agree with you that it would be super if Yamaha do drop their top of the line arrangers and instead add these functions (intro/ending/fill etc) to , as you say, the sequencer section or similar.
That, as you say, COULD be where Yamaha have been aiming all along, and if so, perhaps the arranger per se may be in decline but will be carried on in another form.
It would surprise me in the least to also see Korg move down that path.
They, like Yamaha, already have the technology in existing boards (although Karma in the M3 is way ahead of the arp technology in the XS), so perhaps they too may incorporate the top end arranger into a top end workstation?? And retain a small range of budget arrangers.
