I you want something a little more flexible you can program drums with midi using slate drums or superior drummer or whatever you want and put them on a digitech jamman. Most drum virtual instruments include pre programmed midi in various styles and many different types of kits. I really like the deftones models on my slate drums. This is also a good way to go to an open mic jam by yourself or maybe with say just bass and guitar have some fun. It's also great for practicing when I dont feel like breaking out the laptop to use virtual instruments
