I occasionally use a Nord Stage 3 that is available to me at a rehearsal site. I was allowed to use it in a few performances. and there is no doubt, it has some great sounds on it. I personally think there are equal, if not better sounding piano VSTs (starting with Ivory, and upward). The organ is good, but nothing like what is available in VSTs. The many VST synths available give an unlimited sound source. As for keys, there are some really beautiful simulations out there. You didn’t say anything about Keyscape, but I assume you have at least heard it, and IMHO I think it rules over the Nord. I am quite happy with my VST setup, and found myself wishing I had it on stage instead of the Nord.
But, maybe I needed the familiarity, or I just needed you to program the Nord for me.
