K.O.-sidekick two-channel performance mixer for mobile gear with live FX

The K.O.-sidekick is a compact two-channel performance mixer from Teenage Engineering designed for mobile music setups. It is priced at €189 or $179. The unit includes built-in effects such as a filter with high-pass and low-pass modes and resonance, tremolo, delay, tape, and a loop function with BPM sync. A touch-sensitive pad and a two-directional joystick with a center detent provide controls for quick effect triggering and shaping, and the mixer supports recording and playback of automation.

The mixer offers three selectable EQ styles — DJ, parametric, and studio curves — for per-channel tonal shaping and omits a crossfader in its mixing layout. Two K.O.-sidekicks can be snapped together to create two independent effects buses and expand the system to four channels. Teenage Engineering also offers bundles and EP Pegs to physically snap the K.O.-sidekick to compatible gear. The product is positioned for live performance and mobile music-making gear.

The K.O.-sidekick is a two-channel, performance-friendly mixer designed for compact mobile music setups. Its mixing architecture omits a crossfader and instead presents discrete channel strips for each input. The unit provides three selectable EQ styles — DJ, parametric, and “studio” curves — for per-channel tonal shaping. Two K.O.-sidekicks can be snapped together to create two independent effects buses and expand the system to four channels. Teenage Engineering offers optional bundles and new EP Pegs to physically snap the K.O.-sidekick to compatible gear. It is intended for live performance and mobile music-making gear.

Built-in effects include a filter with high-pass and low-pass modes and resonance. Other effects listed are tremolo, delay, tape, and a loop function with BPM sync. The tape effect permits scratching by working with the playhead, a nod to the OP-1. A touch-sensitive pad and a two-directional joystick with a center detent enable quick effect triggering and shaping. Automation can be recorded and played back for parameter changes over time. “The effect implementation here is pretty brilliant.”

“What if a battle mixer, but for mobile gear, with live FX?”

“There’s no crossfader, which is a bit surprising given the concept.”

“You effectively just get more channel strips.”

“The mod stick and filter give you plenty of other options, though; see below.”

Peter Kirn and other commentators framed the mixer with the question “what if a battle mixer, but for mobile gear, with live FX?” They described “the combination of simple mixing with minijacks and some built-in effects, in a small form factor, looks like a potential winner for live sets with mobile music-making gear.” The commentary also noted that “The mod stick and filter give you plenty of other options, though; see below.” The article referenced optional bundles and “EP Pegs” for physical integration with compatible gear.

On layout and usability the coverage stated plainly, “There’s no crossfader, which is a bit surprising given the concept.” One commentator said, “Personally, I also would have traded at least one EQ band just to get a crossfader,” while another observed, “You effectively just get more channel strips.” Those remarks addressed the mixer’s control choices for performance scenarios.

Control and effect handling were summarized with the quote, “a touch-sensitive pad and a two-directional rocker joystick with a center detent gives you lots of possibilities for quick effect triggering and shaping.” The review also stated, “You can even record and playback automation.” On the tape effect the article observed, “The tape lets you ‘scratch’ by working with the playhead — tape effects date back to Teenage Engineering’s original OP-1.” The piece concluded its assessment of effects with the line, “The effect implementation here is pretty brilliant.” These statements collectively describe reported views on the K.O.-sidekick’s effect functionality and performance controls.

The K.O.-sidekick includes built-in effects comprising a filter with both high-pass and low-pass modes and resonance, tremolo, delay, a tape effect, and a loop function that operates with BPM sync; these named effects are listed as the unit’s onboard effect options. The tape effect permits scratching by working with the playhead, a design element explicitly connected to Teenage Engineering’s earlier OP-1, and that tape-based implementation is described in the article as a deliberate carryover from that lineage.

Control and performance interaction for those effects are provided by a touch-sensitive pad alongside a two-directional joystick with a center detent, and the article states that these controls enable quick effect triggering and shaping during use. Automation can be recorded and played back on the K.O.-sidekick, and the article characterizes the overall effect implementation as “pretty brilliant.”

Two K.O.-sidekicks can be snapped together to create two independent effects buses and four channels, expanding the mixer’s channel count beyond a single unit. The linking is described as a physical snapping connection that allows the units to operate together as a larger system, and that arrangement increases the available channel strips and routes effects across the combined hardware. The article presents this snapping as a means to scale the system for larger performances or more complex routing, and it states that adding a second K.O.-sidekick effectively provides two effects buses and four channels. The available sources do not provide further technical details about the snapping mechanism or the electrical or communication protocol used between units.

Teenage Engineering also offers optional bundles and new EP Pegs intended to snap the K.O.-sidekick to compatible gear, presenting an aesthetic and physical integration system for mobile setups. EP Pegs are mentioned as a way to attach modules together and to align the K.O.-sidekick with other Teenage Engineering products, but the article does not enumerate which products are included in the bundles or the exact Peg designs. The coverage lists the existence of these expansion options without detailing pricing, package contents, or technical implementation specifics. The available sources do not provide this information.
