If i was a gigging musician, i would allways want a backup keyboard...
Imagine you have to say to the freshly wed bride and groome,sorry, no music on your wedding, my keyboard has a problem...
Bachus ... that is very true, but if you are going to have a back up, shouldn't it be the same as your primary board? ... or at least the same brand?
guitpic ... Perhaps you should try to sell the S970 and get a used Pa900 ... at least the OS would be very similar and you
might be able to load some of your Pa4X stuff right into the pa900 ...
