The Roland CR-1000 is a preset drum machine, using the sounds from the more interesting drum machine the TR-505. Only has one mono output and no headphone input. Has basic drum patterns like disco, rock, etc. It does have shuffle and individual levels for the sounds. You can also turn on the clap within a pattern. Bit of an oddity. The only other preset drum machine I've come across is the humdrum Yamaha RX120. The Roland CR-1000 is the ugly half sister of the TR-707 perhaps.
