While you asked I checked them out.
To be fair, I don't usually use other people's patches, and when I do it tends to be as a starting point for my own, so my comments probably won't be very helpful.
There wasn't much I'd use, but I'm not the kind of musician these patches are intended for. I can imagine many people finding them very useful, though, and I'd think you should have a good chance of marketing them.
The one I did like quite a lot was `Nod to Tim' in the pads bank. Can I ask who Tim is? (That isn't just an idle question, by the way.)
