Oh man you have the Korg X50. I'm having one next to me right now and that thing is a bitch! It's supposedly easy to use but I can't even figure out how to change a sound to a certain other sound by pressing just one button, so there would be any use for it live (or generally playing songs with other people)... It has the worst manual I've ever seen!!!
Actually, I tried to update its firmware the other day, and my computer prompts me to set it to "update mode"... Now what the hell is that?? I searched the PDF manual and there is no such thing as "update mode" in the whole manual...!
I'm sure it's easy to use once you get the hang of it, but I think it's the most confusing thing ever. Besides, why are they marketing it to be an ultra-portable synth for live use?? The plastic is cheaper than the plastic on my CME M-Key that cost me 70 bucks! This thing costs over 600 for fucks sake...
It isn't my synth for the record, it's my band's synthist's, but neither of us have been able to figure that thing out...
