I haven't posted any Android apps before, but not for lack of interest. I'd love to see some competition in the tablet space! G-Stomper is the first app to really warrant a post though, and thanks to Matrixsynth for bringing it to my attention.
This drum machine looks like a minimalist-Electribe. It might not be quite as pretty as Korg's iElectribe, but I really like the way all of the pertinent controls are nice big sliders.
