You can still use soft synths with this as a controller - just so that you know, and John mentioned Savi-Host way back in the thread which allows any VSTi to be used standalone.

For me, I don't like weighted keys for when I'm doing synths and organs, but to each his own. I know there are some folks on the forums here who say that it's just a matter of practicing to get good B3 performance out of a weighted keyboard. I don't agree but that's just my opinion/experience. Same for synth leads, although I can do fine if I have a modwheel and pitch bend wheel under my left hand, but that's pretty rare with weighted keyboards.
