Donny, for what it’s worth...I don’t think a modern workstation is what your looking for. I had the Motif XS...which isn’t as nice as the XF...and Mike is right, the arps allow for some cool music to be created, but intros and endings, breaks and fills can be a little challenging. I know you’ve had about every arranger made...so maybe think back to the last one you really enjoyed playing. One that challenged you yet gave satisfaction when you played out or recorded something. Like I said...for what it’s worth, but maybe that’s a place to start.
