Description
The Teenage Engineering PO-33 K.O! (PO33, KO) is a pocket-size micro sampler with a built-in microphone and 40 seconds of sample memory across 16 slots, 8 melodic and 8 drum. It has 16 effects, a 16-step sequencer that chains up to 128 patterns, a built-in speaker, and it runs on two AAA batteries.
Sample anything through the mic or the 3.5 mm line input, play it on the 16 keys, and sequence it into patterns. A breakaway lock tab protects your written patterns, and you can back up sounds and patterns to any recording device through the line out and restore them through the line in.
