Until recently, only 25% of my jobs were arranger ones. Most of those are in restaurants where the volume is low and the tunes are not too busy. Even though I have an unplayed SD-5 and a bunch of other stuff, the MS-60's I have used for years (over 10 years; at least 4 nights per week)suit the task(S) perfectly.
Sometimes I use the little NP-30 or a controller and old Yamaha tone generator on top, but that's about it. That set-up does the job.
Everything else is a combination of a C-1 or XK-1 with an electric piano of some kind, with at least a drummer, and that's a completely different animal.
The SD-5 is a pretty neat keyboard. So is the Midjay I got from DonM. I hope I get comfortable enough to use them before they just fall apart from old age.
George sold me a GW-7 a few years back that has been turned on once to make sure it works. That has been obsoleted by the GW-8 upgrade. He also sold me a SH-201, which would work for my group gigs, but not in the restaurnats, which is all I can do right now, until I heal up a little more. It has been used on one job and turned on two or three other times.
Right now, I'm glad I have arrangers, but most of the time (when I heal up), I'd prefer not to use them. They have a place in the arsenal, but are not my "go to" instruments if I have other options.
