Teenage Engineering has rolled out OS 2.5 for its KO II sampler, introducing new features like lo-fi sample rates, USB audio support, sample reverse, and longer sampling times. These updates significantly expand its creative potential and usability.
Teenage Engineering has released OS 2.5 for its KO II sampler, adding features including USB audio support, lo-fi sample rate options, sample reverse, and an increase in maximum sample length from 20 to 40 seconds. The update, confirmed by the company, aims to enhance the device’s creative flexibility and performance.
The OS 2.5 update introduces audio over USB, allowing users to connect the KO II directly to computers for audio input and output, a feature that was not previously available. It also offers selectable sample rates, including 46 kHz, 32 kHz, and 26 kHz, with the latter providing a distinct lo-fi, crunchy digital character. Additionally, the update adds sample reverse playback and an arpeggiator, expanding the device’s sequencing capabilities.
The maximum sample length has been doubled from 20 seconds to 40 seconds by capturing mono audio, which makes it more suitable for longer samples and loops. Other improvements include enhanced time-stretching, new scales, and per-pad time shifting. The update is also available for the Riddim, Teenage Engineering’s reggae-themed sampler, but only USB audio support for the EP-1320 Medieval sampler is confirmed at this time, with no additional features included.
Expanded Creative Options with Major Features
This update significantly broadens the KO II’s capabilities, making it more versatile for live performance and studio use. Features like USB audio support facilitate easier integration into digital workflows, while lo-fi sample rate options enable users to craft unique, characterful sounds. The longer sampling time and new playback features also enhance the device’s utility for sample manipulation and sequencing, appealing to musicians and producers seeking a portable yet powerful sampler.

Recent Updates and the KO II’s Growing Functionality
Since its launch, the KO II has received multiple firmware updates from Teenage Engineering, transforming it from a simple sampler into a more comprehensive music production tool. Previous updates introduced new scales, improved time stretching, and bug fixes. The OS 2.5 update continues this trend, adding important features that expand its creative potential, especially for live performance and experimental sound design.
While Teenage Engineering has a history of frequent updates, the EP-1320 Medieval sampler remains limited to USB audio support only, with no further enhancements announced. The company has not yet explained why this device is not receiving the same level of update support as the KO II and Riddim.
“The OS 2.5 update for the KO II introduces some of the most significant features yet, especially the selectable sample rates and USB audio support.”
