Teenage Engineering's EP-133 K.O. II takes its legendary PO-33 K.O! into the professional realm, with more power and a workflow that's faster than ever. The EP-133 can store up to nine projects with four groups, each with up to 99 patterns. Each pattern has 12 tracks for samples and MIDI with a variable length per group of up to 99 bars. 12 mono or six stereo voices can be played at a time, with stereo or mono sampling at a 16-bit/46.875 kHz rate. 12 pressure and velocity-sensitive pads, built-in effects, and automation give you all the tools you need to start making music fast.
