I found the EPs to very good. Haven't gigged with it yet, but that will happen soon. SUPER Easy to program as a controller.
A few quirks I discovered: you get 4zones PLUS the internal engine. Although the 4 zones can be split anywhere the internal zone can be split at One Predetermined point, just below middle C.
Also, when using with another midi device, you will need to go into the global menu and turn the midi transmit channel to off. Otherwise, if you call up a preset where you have all 4 external zones are disabled, you'll still transmit. It took me about 15 mins to figure out what was happening with it.
I havent read all 17 pages but I'll assume someone has gushed about the gorgeous feeling of the 73 keybed that only weighs 28 lbs.
I LIKE IT. She's a keeper.
