Teenage Engineering PO-33 KO Pocket Operator Micro Sampler

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.

Lock Tab

Adding to the PO-33 KO's guerrilla mentality is a breakaway lock tab, which allows you to permanently protect all written patterns, restoring all tweaked parameters to locked settings any time you remove the unit's batteries. This process is reversible by soldering the two pads located by the lock tab together.

Transfer Capability

You can transfer sound and pattern data directly between separate PO-33 KOs using the 3.5mm line in/out connectors.

Backup Capability

Sound and pattern data can be stored to any recording device for saving and sharing. You can back up the data via the line out and restore data from a transmitting unit via the line in.
