Playbeat Bundle.

Start with the full Playbeat 4 drum designer, then explore six expansion packs: Nock, Voltage, Orion, Exodus, Ex Ante and Sublation. Playbeat builds patterns around the styles you choose, with a factory sound library, MIDI output and tools for importing your own sounds. The packs add drum kits and patterns that you can rearrange in the included desktop application. Expansions can move between desktop and iPad, but the iPad app is a separate purchase.
