I've owned some Moogs in the past and they do have a fat sound. But, since most keyboards these days are workstation oriented, I'm not too sure how well the LP would actually work for controlling VSTI's. I personally would be looking for something else for a VSTI controller and using the LP for cooking up some killer bass or lead patches for live play.
I am also a member of some other forums, and there is one forum in particular that is sponsored by Keyboard Magazine which has a very large member base. With all respect for this forum, it's sponsor and members , we probably don't cover as much territory here as they do in that forum. The LP seems to be held in high esteem by a number of their members, so someone should be able to give you first hand guidance. Just Google on the related key words to find that forum. Just be sure to read the rules and to introduce yourself. Don
