I'm looking for free or at least inexpensive (under $15) beat grid drum machine plugins for GarageBand. These plugins must work with the new GarageBand (v10+).
High quality drum kit samples are of course preferred, although I'm willing to accept what I can for my price range. Standalone applications that can export GarageBand compatible loops are also acceptable if they maintain a smooth workflow.
Optional suggestions for higher-end (or more optimal) drum machines to consider using in the future are also welcome.
