OXI Instruments: OXI E16

This is an introduction to the OXI E16 by OXI Instruments, available at Takazudo Modular.

OXI E16 is a portable MIDI controller equipped with 16 encoders. Packed into a compact aluminum unibody, it integrates LED ring-equipped encoders and an OLED screen, enabling integrated control of modular synths, hardware synths, and DAWs.

Powerful Yet Simple MIDI Control

With OXI E16, you can manage up to 16 scenes (7 directly accessible from the home screen, the rest selectable from the Shift menu). Each scene has 12 customizable pages, with 16 controls on each page. This means a total of 192 parameter controls can be mapped per scene.

Furthermore, each control can have 2 destinations and 1 push action, giving you effectively up to 384 control targets per scene.

This flexibility allows you to control multiple synthesizers, effects, and modular systems from a single compact device.

Key Features

Snapshot (A-B Morphing) Function

You can set one encoder as a primary snapshot control and link multiple secondary controls to it. Save two states, A (lower limit) and B (upper limit), and simply turn the primary knob to seamlessly morph all linked parameters within their respective ranges.

This makes it easy to create dynamic sound transitions, such as simultaneously and smoothly varying multiple filter cutoffs or effect parameters.

Knob Recording

The ability to record and play back encoder movements makes the E16 a powerful modulation generator. Capture knob movements in real time and loop them for complex automated performances.

Encoder Grouping (Groups)

You can create up to 4 groups and link multiple encoders together. Controls within a group can have two roles:

  • Primary Lead: Turning this knob causes all other knobs in the same group to change their values relatively
  • Secondary Follower: Follows the lead knob while still allowing independent adjustment

The amount of influence (percentage) each follower receives from the lead can also be individually configured, enabling nuanced control.

Real-Time Feedback

The OLED screen displays parameter values in real time. Each encoder's LED ring also provides visual feedback, allowing you to check current settings at a glance even on dark stages.

Preset Function

Each scene has 16 preset slots, allowing you to save and recall the current state of all knobs. This is convenient for quickly switching settings during live performance or comparing different sound variations.

Instrument Definitions

Through the OXI App, you can download pre-defined MIDI CC mappings for various synthesizers and effects. Compatible with devices from numerous manufacturers including Elektron, Korg, Moog, Arturia, Dave Smith Instruments, and Modal Electronics, it eliminates the need to manually set CC numbers. When you select an instrument definition, parameter names are automatically applied as well.

Connectivity

OXI E16 offers diverse connectivity options for modern music production environments.

  • USB-C port: For power supply (5V DC 1.7A) and MIDI USB communication. Can be powered from PC/Mac, mobile batteries, etc.
  • 3.5mm TRS MIDI interface (Type A): 2 MIDI OUT + 1 MIDI IN. Each output can be configured as "Thru" to directly pass through received MIDI data
  • Bluetooth MIDI support: Bluetooth 5.0 BLE bidirectional communication. Supports peripheral and central roles for wireless connection with mobile devices and tablets

Specifications

  • Size: 143mm x 114mm x 19mm (30mm including knobs)
  • Weight: Approx. 950g
  • Housing: Aluminum chassis, robust and professional build
  • Encoders: Non-Detented type (smooth rotation without click stops)

The compact design makes it perfect for both studio and live use.

Using the OXI App for PC/Mac makes E16 setup and management even easier.

  • Scene Editor: Intuitively compose scenes with drag and drop
  • Instrument Definitions management: Download instrument definitions from the database and transfer to E16
  • Firmware updates: Easily apply new features and bug fixes
  • Backup and restore: Save and restore scenes and presets

OXI App can be downloaded from the OXI Instruments official site.

Integration with the OXI Ecosystem

OXI E16 becomes even more powerful when combined with OXI ONE or OXI ONE MKII. Use E16 as a control surface for OXI ONE, or as an integrated control center for your entire modular system.

In Eurorack environments, combining it with modules like OXI Coral and OXI Meta allows you to build a fully integrated performance system.

  • Those who want integrated control of multiple synths during live performance
  • Those seeking hands-on control of their DAW
  • Those who need a compact, portable MIDI controller
  • OXI ONE users looking for further expandability

Included Accessories

  • OXI E16 unit
  • USB-C to A cable
  • OXI E16 protective case (travel case)
