Unlike with some other synths/patches the mod wheel should be left alone, as many sounds here already has a dialed in amount that suits the patches. Moving the mod wheel will in many cases ruin the patch and become something else completely.
I've used noise as a mod source quite a lot in many of these patches.

A couple of patches have notes/instructions (...) in the title to invite the user to play with them the intended way.
Feel free to check them out.
