Until recently I used a Yammie DGX-500 as a controller for my PA1x Pro but I recently added a computer to my live set up and I couldn't comfortably reach both keyboards, the computer keyboard and my Music Pad Pro from one position so I had to let something go. Since I love the Yammie's piano sound and having 88 keys it was hard but I had to retire it from the live set up. Now I just use the Pa1X and a computer I built from scratch for music purposes only (and URU games).

I'm kinda looking at the PA-588....


anyway, hope that answers your question.
