I have some samples I'm working with now but it takes more time than I want to give the project. Like you, drumming is not something I feel qualified to do to get what I want. But, have gone this far so I may continue.
Never tried Jamstix. Have EZ Drummer but don't really like the sound of it. Read an article in Electronic Musician where the guy layered the drums from different drummers such as EZ Drummer and another such drummer. Might be something to look into.
Anyway, thanks for the reply, Guitarhacker. Will give Jamstix a look on their website.
