I can tell you about GEM WK/SK series.
Those keyboards when powered on, they default to performance one automatically. So all your basic standard setup can be saved 100% in performance one, so that when you powerup, your +3 will be there. Your dsp is correct. Your favourite partitioning of the keyboard is there. Your most common instruments are prepared...
That is the second time I reply to a post of yours, and in both times I said SK880 does it right and good. Hmmmmm, wanna switch to WK8SE? George Kay can help.
