Elektron Outbox 8 — Information from Sweden

video upload by Elektron

"Outbox 8 adds eight outputs for configurable audio and CV, meaning you can turn your compatible Elektron machine into an octopus of connectivity. Add external effects. Separate your tracks out to a mixer or wherever. Control and sequence your modular gear or any other CV-equipped devices. And though Outbox 8 is predominantly made with your Elektron units in mind, it can do the same with a bunch more class-compliant gear too. Break out your sound and control, whatever the moment calls for."

"Eight-channel audio/CV breakout box

Outbox 8 is a versatile eight-channel audio/CV breakout box and USB host/device designed to expand your connectivity, with creative possibilities to boot. It adds eight fully configurable physical outputs to a compatible connected device, letting you send audio and CV in any combination its capabilities allow. Route your sound and control wherever the moment calls for.

Send audio

Outbox 8 enables you to route individual tracks for external processing, mixing, or performance – creating a flexible bridge between your Elektron workflow and the wider world of sound and control.

MIDI to CV

With Outbox 8, you can assign outputs to CV duties – pitch, gate, trig, linear value, or clock. Use it as a dedicated USB MIDI-to-CV converter to play, sequence, modulate, and synchronize modular systems and other CV-capable instruments. Or connect a MIDI controller to play and control them directly.

This makes it easy to integrate MIDI controllers with modular setups – combining the familiarity of keys and performance gestures with the flexibility of voltage-controlled sound.

Eight-output computer audio

Connect Outbox 8 to your computer, tablet, or phone and use it as an eight-output USB audio interface – ideal for clean, portable, and reliable setups. You can route audio directly from your DAW to monitors, mixers, or external hardware using a single streamlined device.

At the same time, MIDI from your DAW can be sent to Outbox 8, allowing any of its outputs to be configured to send CV. This lets your computer sequence modular gear, control analog synthesizers, or synchronize external devices – and extends your studio beyond the screen and into hands-on soundcraft.

In-device or web app setup

For many Elektron boxes you are able to set up Outbox 8 in-device. Just connect and control. Outbox 8 can work a little differently depending on your machine, so check this page’s Compatibility Matrix.

For others, and a wide range of non-Elektron USB class-compliant devices, you can configure Outbox 8 by using the Outbox 8 Web App – available here (please ensure your browser is able to run Web MIDI).

Audio/MIDI compatibility can vary by manufacturer and firmware. Many will work with MIDI, some with audio, and some with both.

Compatibility Matrix

* Model Samples and Model Cycles can only route the audio from the main outputs.

** DIN or TRS MIDI needs to be converted to USB MIDI using a class-compliant MIDI-USB interface.

*** Limited functionality (High audio streaming latency and no in-device setup)

On Digitakt II and Digitone I/II, you can configure audio outputs in-device as either individual mono outputs or as combined stereo pairs.

Connectivity

Alongside your eight audio/CV outputs are two USB-C ports, one for connecting to your device or computer, and one for power input when needed.

However you’re setting up, the front-panel LED keeps you in the loop, communicating connection and configuration status at a glance.
