Oberheim DX MIDI Upgrade
A MIDI upgrade for all non-MIDI Oberheim DX and Stretch drum machines is now available from Electrongate!
This upgrade adds MIDI input and output capability and additional clocking options to your DX.
When installed, your DX 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 DX and a circuit board is installed inside.
(The MIDI upgrade can be mounted on top of the sync-to-tape circuit board, if your machine has that option).
This interface will make your DX functionally equivalent to the Oberheim DXa.
You can download a copy of the DXa manual which covers most of the new
features of this upgrade here:
