Randomise patches!
 

Never used this feature until last week, but it really is surprisingly usable.

Select a patch, dial in how much randomisation you want, then hit Store to randomise. If it's not to your taste, you can keep hitting Store and it'll continue to randomise. Found some really great patches this way. It's also useful when you're stuck in a rut with a few of your sounds, and wish to individually spruce them up.

I need more user RAM bank storage!

And you can parameter lock the sections you don't want randomised.
