mLab OB-X MIDIcontrol

The magicBox for the last OBX revision with a 37-pin connector

Oberheim OBX magic Box

gives you RealTime MIDI access to all OBX parameters.


Installation

The interface needs an external power supply (not included)
The power supply should output 5…9V DC where the center pin = (+)

If you don't like to use an external power supply,
you can supply your interface from the OBX by doing a Little modification.

The installation is much more easy than any other MIDI retrofit.
We leave your Oberheim Synthesizer completely untouched.
Just plug the magic box into the Computer Port at the rear panel of your OBX,
and you have real time access to more than 40 parameters.

It’s that easy.
