Total MIDI Control

MIDI isn’t just about triggering notes -and the Oxygen series has what it takes to access all those deep parameters in your software and hardware so you can get the most out of them. Map the eight knobs to any synth parameters you want to program or perform with -or to mixer controls like volume, panning and effects send. Assign the buttons to trigger samples and anything else that is MIDI-programmable. Assignment is simple, yet has the power to let you delve as deep as you want. Each controller can map to just about any applicable parameter in the MIDI spec, including independent channel addressing for each. The possibilities are limited only by your imagination.

Easy Programming

Oxygen controllers feature dedicated front-panel function buttons to easily access common operations like preset, program or channel up/down, octave up/down, and transpose up/down. Use the Controller Mute button to prevent parameters from jumping when you change them, then press Snapshot to transmit all current settings. The Advanced Function button allows the keyboard to serve as a data-entry device for controller assignment and similar setup functions. The front-panel 3-segment LCD gives you the information you need for programming parameters at a glance. 10 non-volatile memory locations instantly save and recall your favorite presets, and you can manage an entire preset library on your computer via SysEx dumps and the free Enigma software editor/librarian for PC and Mac.

Free Enigma Editor/Librarian Software

Download Enigma powerful software editor/librarian for Mac and PC that lets you easily program, store and load setups for M-Audio and Evolution USB MIDI controllers.

With Enigma, your library of controller presets is virtually unlimited.
