Big difference between Krome and Kronos...

I played a 61 Krome that a friend has. Felt so light, it wouldn't stay put on the stand..! I'm not the heaviest handed of guys, but I do play strong enough to get a decent 127 out of the things when I get frisky, but that thing would move around on the stand with MUCH lower force.

TBH, I was not all that impressed. Didn't seem all that live band friendly (nice if you have your presets ready to go, not so good at creating splits and layers on the spot) and felt pretty cheap.
