Fran.....I didn't even notice that I was playing a Jupiter (still have it). The board in front of me is a Yamaha PS-6100. Don't remember what else I was playing. I have a lot of Roland keyboards. I eventually changed the setup to two keyboards in front of me....Pro E on top, DX7 underneath, Roland U-20 on my right...on the floor a U-20 module controlled by my left hand on the DX7, 2 volume pedals, and one wah-wah for the guitar sounds. Pro E was used mostly for the styles. A perfect comfortable setup....used it for years.
Yes, you reminded me the Pro E IS bigger than a laptop.
