The Wersi is by no means an organ any more than any other arranger or workstation keyboard is. Sure some people use arrangers/workstations as organs but I doubt many people would pay a premium price for any instrument if that's all that it was capable of. The Wersi does far more than organ sounds and the simple style demo's Bill posted are in no way reflective of the actual instrument sounds on the Wersi. All it shows are some basic styles using mostly GM/GS/XG based sounds and its not remotely indicative of what the Wersi factory sounds are like. Not unlike most keyboards the GM/GS/XG sounds are far from stellar.

I didn't find the styles Bill posted to be bad but they weren't great either. I own a Wersi OAS 7 and if I didn't know what the instrument truly sounds like or its incredible capabilities, I'd probably think it wasn't good from the style demos alone. Thankfully I know better.
