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.
New! The currently shipping version of the Electrongate MIDI
upgrade now
includes an on-board lithium battery which replaces the old, leak-prone
NiCd battery. The lithium battery is the same as those used on
the Oberheim DX, and is reliable and has a very long lifetime, in
excess of ten years. (Many DX units using this type of battery are still
working with the original battery, even after 30 years or more).
The new MIDI upgrade design also includes a MIDI Thru
connector on the board, so you can choose MIDI Out, or MIDI Thru
as well as MIDI In. If there enough demand, a three-jack mounting
plate may be added as an option in the future.
Available installed by Electrongate or install it yourself for
$129 to $179.

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.
