Teenage Engineering EP-127 K.O.-PEDAL Voetschakelaar

Wireless Foot Controller for the EP-35 K.O.-AMP

The Teenage Engineering EP-127 K.O.-PEDAL is a wireless foot pedal controller designed to expand the EP-35 K.O.-AMP with hands-free performance control. Two pressure-sensitive, foot-sized buttons sit under a compact 176 x 84 x 26 mm housing, giving guitarists and vocalists expressive control over effects, looping, metronome and music playback without taking their hands off the instrument. The EP-127 K.O.-PEDAL pairs with EP-35 over Bluetooth LE or USB-C, and also works as a standalone MIDI and HID controller for DAWs, synth apps and external pedalboards.

Expressive Foot Control Beyond a Basic Footswitch

Unlike a simple on/off footswitch, each button supports five distinct gestures: press, double-press, tap, force-press, and continuous actuation by rocking the foot forward and backward. A hidden switch inside the battery compartment toggles between MIDI state and HID state, where the buttons send left/right arrows, 'm' and space-bar keystrokes for video playback and presentation control. Four modes — FX, Looper, Metronome and Music Playback — are cycled with a dedicated mode button, while the BT button switches between the guitar and mic channels on EP-35.

Connectivity That Fits Any Studio or Stage Rig

Connectivity is the EP-127's strongest asset, letting it slot into both the EP-35 ecosystem and a broader MIDI setup. Bluetooth LE MIDI pairs the pedal with phones, computers and field devices, while USB-C handles wired MIDI, HID and power through a single cable. A 3.5 mm TRS MIDI out jack drives synths and pedalboards, and a 3.5 mm expression pedal input lets a separate volume pedal adjust the selected channel on EP-35.

• USB-C: Yes — MIDI, HID and 5V/0.5A power over a single cable
• Bluetooth LE: MIDI and HID — wireless pairing with EP-35, DAWs and apps
• MIDI Out: 3.5 mm TRS jack — drives external synths and pedalboards
• Expression Input: 3.5 mm TRS — for an external volume pedal

Two Buttons, Five Gestures, Four Modes

The control surface is intentionally minimal but unusually expressive, packing five gestures into two foot-sized buttons. A dot-matrix display shows the current mode and parameter state, while the BT button switches channels and activates pairing. In MIDI state, the four modes map to documented CC outputs — CC12/13 for FX, CC82/83 for the looper, MIDI clock for the metronome, and CC1/64 (mod wheel and sustain) for music playback.

• Number of Buttons: 2 pressure-sensitive — press, double-press, tap, force-press and continuous actuation
• Modes: FX, Looper, Metronome, Music Playback — cycled via the mode button
• HID State: Keyboard shortcuts — left/right arrows, 'm' and space bar for media control

Compact, Battery-Powered and Stage-Ready

The housing measures 176 x 84 x 26 mm and weighs just 0.2 kg, making the pedal easy to slip into a gig bag alongside the EP-35. Power comes from two AAA batteries — good for around 20 hours of playtime and one month of standby — or from any USB-C source. The chassis uses PC/ABS and PC plastics with silicone rubber buttons for road-friendly durability.

• Dimensions: 176 x 84 x 26 mm — slim enough for a small pedalboard
• Weight: 0.2 kg — light enough to carry to every gig
• Battery Powered: 2x AAA — 20 hours playtime, 1 month standby
• Materials: PC/ABS, PC, silicone rubber — road-tested plastics and tactile buttons
• Compatible With: Teenage Engineering EP-35 K.O.-AMP — primary pairing target
