The arranger module market is a tiny piece of the already small arranger pie...so why would a manufacturer go to the trouble/expense of developing one, just to get a portion of an already small segment?

It may be more likely to see accordions sold with arranger units built in...Roland's V-Accordion would be a great candidate.

There must be some way to get the innards of the GW-8 or McPrelude into one of those units?

James, the QY-700 was the ultimate end product of Yamaha's QY "Walkstation" line.

I very nearly bought one when Yamaha was clearing out the warehouse at year's end....back then I was using a cut down Clavinova CLP-300 and an Roland RA module.

I decided to go with 61 keys and forgo the piano altogether (most gigs were becoming more arranger based), especially when the PSR-8000 came out.

Still, the QY-700 was a quite a smart concept...wonder where they could have taken it, especially with today's technology?
