anybody who needs drums and rhythms to go along with their live music creations; the Korg Stageman 80 is a device to consider. it comes with a large library, and allows to create/record own recordings, and even edit and mix them, right on the device. not sure the later is really required with a laptop becoming almost a defacto standard tool for any musician. that said, its cool the mixing and editing can be done without such laptop, tablet or other device required.
