Oberheim DMX MIDI Upgrade

A MIDI upgrade for all non-MIDI Oberheim DMX drum machines is now available from Electrongate!

This upgrade adds MIDI input and output capability and expanded memory capacity to your DMX. When installed, your DMX will send and receive MIDI note-on/note-off messages, system exclusive sequence dump messages and MIDI clock, song select, start and stop messages. MIDI input and output jacks are added to the right side panel of the DMX and a circuit board is installed inside. (The MIDI upgrade replaces the memory expansion board on machines having that option installed.)

This interface is functionally equivalent to the Oberheim factory MIDI upgrade, which is no longer available.

See this pdf file for a detailed list of MIDI related edit parameters provided by this upgrade.

Available installed for $170, or install it yourself for $129 to $149.

    Upgrade options:
  1. Full upgrade: Send your DMX to Electrongate in San Jose, California and have the MIDI upgrade professionally installed and tested for $170.
  2. Do-it-yourself: Assembled circuit board and modified walnut end panel with MIDI jacks installed: $149.
  3. Do-it-yourself: Assembled circuit board with unmounted MIDI jack plate: $129. You will need to make a cutout in the right side panel for the MIDI jacks. You may also send your right side end panel with your order, and we will modify it for the MIDI jacks at no extra charge).
Do-it-yourself requirements
To install the DMX upgrade yourself, you will need the following tools:
  • #2 Phillips screwdriver
  • 1/4 inch nutdriver
  • Small flat-blade screwdriver, or IC chip puller tool
  • Soldering iron and rosin core solder
  • Xacto® or other sharp knife
You will need to cut one circuit board trace and solder two wires to the DMX main board. The rest of the installation is very straightforward and mainly involves removing socketed ICs and plugging in ribbon cables.

Illustrated installation instructions can be found here.
