EP-136 K.O. Sidekick — Mixer, Effects Unit and Sequencer

The EP-136 K.O. Sidekick is a compact unit that combines a two-channel mixer, an effects processor and a built-in sequencer for Teenage Engineering’s EP-series setups. It is presented as a mixer with an integrated audio interface and as a dedicated effects unit with sequencing functions, and the form factor is described as compact and intended for integration with other EP-series instruments. The device includes physical controls and a user interface intended to manage mixing, effects and sequencing tasks in a single unit. The design emphasis is stated as supporting both hands-on control and digital audio workstation integration.

As a USB 2.0 audio interface the Sidekick provides eight input channels and four output channels, and it offers two 3.5mm stereo inputs plus a stereo aux for a third session input. The unit includes six onboard effects — filter, delay, loop, tape, tremolo and siren — and it provides a high-resolution colour LCD for navigating settings. Control hardware comprises a bi-directional modulation stick and a pressure-sensitive force pad, and the Sidekick can run on two AAA batteries or via USB-C power. Multiple units can be chained for expanded channel counts, and mounting points allow the Sidekick to snap onto the TE EP-133 K.O. II.

Core technical features of the EP-136 K.O. Sidekick

The EP-136 K.O. Sidekick weighs 300 grams and measures 1.6 centimetres thick. It operates as a two-channel mixer with an integrated audio interface and is designed to sit between EP-series units and a digital audio workstation. Multiple units can be chained together to expand channel counts and mounting points allow the Sidekick to snap onto the TE EP-133 K.O. II. The unit is described as suitable for studio or stage use.

As a USB 2.0 audio interface the Sidekick provides eight input channels and four output channels and also offers two 3.5mm stereo inputs plus a stereo aux for a third session input. Power options include running the unit on two AAA batteries or powering via USB-C. The product is supplied with a starter pack that bundles essential cables and connector pegs to simplify connections in multi-unit or DAW-integrated setups. The unit includes a high-resolution colour LCD for navigating settings and control elements such as a bi-directional modulation stick and a pressure-sensitive force pad for expression and parameter control.

Effects and control features

The EP-136 K.O. Sidekick includes six onboard effects: filter, delay, loop, tape, tremolo and siren. The unit’s user interface features a high-resolution colour LCD for navigating settings and effect parameters, and the onboard effects are supplied as part of the Sidekick’s standard feature set. The device is presented in product material as both a mixer and an effects unit with sequencing functionality, and the effects are listed together with the unit’s sequencing and mixing capabilities. Control elements, user interface elements and the listed effects are provided as factory features of the product.

Control hardware on the Sidekick comprises a bi-directional modulation stick and a pressure-sensitive force pad. These controls are used to access effects and sequencing functions on the unit. “The plan was to build a mixer for the K.O. II but it became more of an effect-box with a built-in sequencer,”. “See it as a dj mixer with a 2-bar looping effects-automator, or whatever you wanna call it.”

Integration and Compatibility

The EP-136 K.O. Sidekick is designed to sit between Teenage Engineering’s EP-series units and a digital audio workstation, providing hands-on routing, mixing and effects control in hybrid hardware–software setups. Multiple units can be chained together to expand channel counts, and physical mounting points allow the Sidekick to snap onto the TE EP-133 K.O. II for compact hardware integration. The product is offered with a starter pack that bundles essential cables and connector pegs to simplify connections in multi-unit configurations and to support setup in live or studio rigs.

Functioning as a USB 2.0 audio interface, the Sidekick provides eight input channels and four output channels and also offers two 3.5mm stereo inputs plus a stereo aux for a third session input. Power options include running the unit on two AAA batteries for portable operation or powering via USB-C for fixed installations. These interface, power and mounting features are documented together with the device’s control and effects capabilities, and the unit is described as suitable for studio or stage use.

Attributed quotes on product concept

The available material includes two direct quotations that describe the EP-136 K.O. Sidekick’s concept and design intention. “The plan was to build a mixer for the K.O. II but it became more of an effect-box with a built-in sequencer,”. “See it as a dj mixer with a 2-bar looping effects-automator, or whatever you wanna call it.”

No speaker attribution is provided alongside these quotations in the material. The quotations present the device as having shifted from a planned mixer to an effects-focused design with sequencing functionality and frame the unit as comparable to “a dj mixer with a 2-bar looping effects-automator.” The available sources do not provide any further attribution information for these quotations.

CONCLUSION

The EP-136 K.O. Sidekick functions as a two-channel mixer, an effects unit and a built-in sequencer for Teenage Engineering’s EP-series setups. It weighs 300 grams and measures 1.6 centimetres thick, and it includes mounting points that allow the unit to snap onto the TE EP-133 K.O. II. Interface features include a high-resolution colour LCD, a bi-directional modulation stick and a pressure-sensitive force pad, and as a USB 2.0 audio interface it provides eight inputs and four outputs. The Sidekick also offers two 3.5mm stereo inputs plus a stereo aux for a third session input, and it can run on two AAA batteries or be powered via USB-C. The product is supplied with a starter pack of essential cables and connector pegs, is priced at $169, and is described as suitable for studio or stage use.
