Teenage Engineering Overhauls EP-133 KO II with OS 2.5

The update doubles the maximum sampling capacity to 40 seconds by allowing mono capture, a practical shift that pairs with equal-length autochopping to streamline loop manipulation. While the device previously relied on transient detection for chopping, these new tools make it significantly more efficient for melodic sampling. The addition of sample reversal and an arpeggiator further expands the unit's utility, simplifying the creation of synth-style basslines and complex rhythmic patterns.

Perhaps the most notable creative addition is the selectable sample rate. Users can now toggle between the standard 46 kHz, a 32 kHz mode for added texture, and a 26 kHz setting that leans into gritty, digital distortion. The update also brings improved time stretching and per-pad time shifting to the platform. While the OS 2.5 rollout extends to the reggae-themed EP-40 Riddim, the specialized EP-1320 Medieval remains largely sidelined, receiving only basic USB audio support.
