The Teenage Engineering PO-33 KO is a micro sampler designed to provide easy and creative sound creation and sequencing for producers, beat makers, and sound designers in studio sessions or on the go. Record up to forty seconds worth of samples via the built-in microphone or 3.5mm stereo input jack to any of the eight melodic slots or eight drum slots. Utilize the sixteen-step sequencer and sixteen patterns to program your samples into a beat or melody, then choose from sixteen effects for additional manipulation.

Monitor through the built-in speaker or connect the 3.5mm stereo audio output to a mixer or headphones. The audio I/O can also be used for jam syncing multiple Pocket Operators and backing up, restoring, and transferring sound and pattern data. An integrated clock and alarm clock expand the creative possibilities of the instrument, which is powered via two AAA batteries (available separately) for mobile convenience. A foldout stand enables both hands to be used for more efficient operation.
