QuickTime (MP4) | iOS MP4
Hard to describe this as its such a unique idea. sort of like a virtual tambourine/drum machine/synth/looper.
The Zoom ARQ looks like a whole lot of fun. Its got two parts, the base station which contains all the IO and brains for the effects, drum and synth voices, and sample playback, and the ring controller - which is like a tambourine sized pad controller with positional sensors.
Maybe the Zoom ARQ product page will be able to explain things.
