Teenage Engineering adds lo-fi mode, USB audio, and more to its KO II sampler
Teenage Engineering has released OS 2.5 for the EP-133 KO II sampler, introducing USB audio, selectable sample rates for lo-fi effects, sample reverse, an arpeggiator, and other features. The update also comes to the Riddim model, while the medieval-themed EP-1320 only gets USB audio support.

Teenage Engineering continues to enhance its $329 EP-133 KO II sampler with a substantial software update. OS 2.5 adds audio over USB, selectable sample rates (standard 46 kHz, 32 kHz for character, and 26 kHz for a full lo-fi digital crunch), sample reverse, an arpeggiator, equal-length autochopping, and extends maximum sample length from 20 to 40 seconds by capturing mono audio instead of stereo.
These new features make the KO II much better suited for melodic material and rearranging loops. The arpeggiator is particularly notable for creating synth basslines, and the longer sampling time with equal-length autochopping improves sample chopping.
Other improvements include better time stretching, new scales, per-pad time shifting, and numerous bug fixes. The update is also available for the reggae-themed sibling, the Riddim. The bizarre medieval sampler EP-1320 receives only USB audio in its OS update, with no other features. Teenage Engineering has not responded to inquiries about why the EP-1320 is often left out.
