It's not just Yamaha arrangers. Arranger are EVERYWHERE. Just because you don't see them on stages doesn't mean they're not being used in studios. Arrangers by Yamaha, Korg, and Roland ARE in studios of the pros and in their homes. The problem is MANY are too proud to admit they use them

Arrangers DO get used by the pros every day. Just because you don't see them on stage doesn't mean they're not getting used by them. I've gone into studios to find great set ups.., AND arrangers. I was really shocked when going into one guys studio and he APOLIGIZED for having a Korg PA-80 in his studio. Many pros feel they're not going to get taken seriuosly if they have an arranger. I disagree with that.., but hey that's the age old stereotype for ya.., and it ain't gonna change anytime soon.
