Ian,
Yes, of course it's only a theory... but a darn good one. The arranger has grown up!
It's not that little toy cheesy sounding thing of the past! It's now a wonderful great sounding instrument with many PRO features and sounds. Some of the sounds are better than the synths(Motif).

Like Diki said, it would be trivial to build one so why not?

Divisional rivalry makes no sense, you kidding, I worked for a very large company, IBM... you bet it goes on every day.

At IBM, I attended many meeting where we talked about product/marketing etc involving our customers and we treated the 'other' division like competitors! Both divisions had products that could basically solve the customers problems. We each had our own sales quotas and pot of money.

Example: The motif can now do styles as such. Not the same as we do with T2, but it is styles (phrases). I heard it demoed last weekend at Sweetwater Gearfest. Sounded a lot like styles to me. Why would PRO synth players want that? The line is getting closer and closer between arrangers and synths (workstations)
