Hi there. I'm a new user (just joined) and saw your post about using BIAB styles on an arranger keyboard. I do just that with my Korg PA1X arranger. I see you have a Yamaha keyboard so it's no good my telling you how I do it as I am sure it wouldn't work on a different make of keyboard, but do persist in trying as some of the BIAB styles are first rate and I use them freely on the occasional gig. Incidentally, I got my info from the Korg user forum; there's absolutely nothing about it in the PA1X manual!! Good luck.
