The thing is, if you are using MP3's for the primary backing (or playing with a live band), all you are changing out is the actual keyboard sounds you use live. Most of us could change around pretty freely for that, but the minute you have to prepare SMF's or styles for the gig for each keyboard, doing something like this looks like WAY too much work!

I know I'm an old stick in the mud, but once I find something that covers all the bases adequately, I don't really feel the need to prove to myself that I made the right decision by trying everything else briefly...

Bottom line is... you went through all that change, and you'll be back on the G70 before long I'm doing primarily all live band work this summer, could take my K2500 or the Triton, but neither of them would work as well, and be as versatile as the G70. I can't honestly think of any of those other keyboards doing a significantly better job at any sound for a live gig, and none of them cover ALL the bases as well as the G70.

You are working way TOO hard, my friend
