Elektron Outbox 8 - 8-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 connected device, letting you send audio and CV in any combination its capabilities allow.

Route your audio to mixers, effects, and more - channel by channel. Or convert MIDI into CV signals to control your modular rig and other CV-controllable devices. Whatever the moment calls for.

Outbox 8 is compatible with Elektron Overbridge-enabled units, USB class-compliant MIDI devices, and many USB class-compliant audio devices.

USB MIDI support is broad, while audio compatibility can vary by manufacturer and firmware; check Elektronauts for the latest confirmed devices. Outbox 8 also works as an audio interface, adding eight more outputs to your computer.

Send audio

Outbox 8 enables you to route individual tracks or submixes from your compatible Elektron machine for external processing, mixing, or performance.

Send CV

With Outbox 8, you can assign outputs to CV duties - pitch, gate, trig, value lin, or clock - to bring modular and other CV-controllable gear into the same setup.

MIDI to CV

Use Outbox 8 as a dedicated USB MIDI-to-CV interface. Play, sequence, modulate, and synchronize modular systems and other CV-capable instruments with your Elektron box. Or connect a MIDI controller to play and control them directly.
Eight-output computer audio

Connect Outbox 8 to your computer, tablet or phone and use it as an eight-output USB audio interface. Route channels from your DAW to mixers, effects, monitors, or other external hardware, while also converting MIDI into CV where needed.

Key Features

• 8 fully configurable outputs – each of the eight 1/4" impedance-balanced, DC-coupled outputs can be set independently to send audio or CV
• Flexible audio/CV routing – mix and match: all audio, all CV, or any combination across the eight outputs
• Per-track audio routing – route individual tracks, submixes, or duplicated signals from a compatible Elektron device to any output
• MIDI-to-CV conversion – seven CV signal types: Grounded, Pitch V/Oct, Pitch Hz/V, Value Lin, Trig, Gate, and Clock
• Dual setup methods – configure directly on supported Elektron devices (in-device menu) or via the browser-based Outbox 8 Web App
• Device profiles – stores up to 8 device profiles plus one dedicated computer/host profile, so settings are remembered per device
• On-board mixer page – adjust output levels directly from supported Elektron devices without leaving the sequencer
• USB audio interface – doubles as an 8-output class-compliant USB soundcard for any computer, tablet, or phone
• USB host or device – works as a USB host for Elektron gear, or as a class-compliant device connected to a computer
• Broad compatibility – supports Overbridge-enabled Elektron units, USB class-compliant MIDI interfaces, and many USB class-compliant audio devices
• 48 kHz, 32-bit D/A converters – for clean, high-resolution audio output
• Status LED feedback – colour-coded LED shows connection, streaming, host/device mode, and error states at a glance
• Recovery mode & factory reset – built-in safeguards for firmware issues, accessible via a simple pinhole reset
• Compact, bus-powered design – aluminium casing, powered via USB-C, no external power supply required in most setups

Use Cases for Outbox 8

• Expand your Elektron device's outputs – break a single stereo output into up to eight individually routable channels for external mixing or processing
• Live performance mixing – send kicks, drums, bass, and leads to separate mixer channels for hands-on EQ, level, and effects control
• Send tracks to outboard effects – duplicate a track's signal to a reverb, delay, or other hardware processor while keeping the dry signal on its own channel
• Control a modular synth from an Elektron sequencer – convert MIDI note, velocity, and CC data into pitch, gate, trig, and clock CV to sequence modular voices in sync
• Modulate modular gear with an Elektron device – use LFOs or parameter locks on an Elektron track as a CV modulation source for filters, VCAs, or other modular parameters
• Hybrid audio + CV rigs – combine some outputs as audio sends and others as CV/gate/clock outputs from the same box
• Studio audio interface – use Outbox 8 as an 8-output USB soundcard for a DAW, routing channels to monitors, mixers, or hardware processors
• Standalone MIDI-to-CV converter – plug in a USB MIDI keyboard or controller and play modular or CV-equipped synths directly, without a computer
• Add outputs to non-Elektron gear – connect a class-compliant groovebox, synth, or drum machine with only a stereo output and unlock multiple discrete outputs via Outbox 8 acting as USB host
• Multi-format performance rigs – submix internal tracks to a single output, or send one track to multiple outputs, depending on the setup
