I'm not sure that I've used the VSC... I may have, just not sure.
I tried a number of softsynths & nothing compared to the Hyper Canvas overall.
There are a couple glitches in Hyper Canvas that Roland knows about & said they had no intentions of fixing. The one I've experienced often is "the rogue bass drum". The volume just jumps & isn't consistent with the rest of the drums. (not all the time tho'!)

I generally use SampleTank for the drums now.
