It is a well-known sequencer, an evergreen. It had two types, black and grey series, i think there is no major difference, but black looks better and they're newer also. It is very simple and very easy to use. You can turn on and off 8 tracks, but in one track You can go up to 16 multitimbrality, so it is great! Save Your songs to oldskool casette tapes... Perfect for a live-act.
