I like to use multiple keyboards. At my country club job, it's a B-3 with an old mirco-Korg on the top and a Rhodes on my right hand.
At another week-end house job, it's an MS-60 and a controller with an old Yamaha tone generator (that equipment-both places- stays on site). Alwways use two boards, again, because of years of playing a B exclusively.
Still have the GW-7, G-70, Sh-201, Midjay and controller in boxes, along with an XB-2 I bought years ago and never used. I'm going to take the time to get up to speed on this equipment before the end of the year and use it-in some combination-in 2008.
