“Oberheim DX Drum Machine w/ Electrongate MIDI upgrade
Working but has some issues:
1. The memory becomes corrupted every few times the unit is powered up. Sometimes it doesn’t happen for weeks, sometimes it will happen every power-up. When it does happen, you are prompted to reset the memory. This clears settings, patterns, etc and then the machine functions normally until the next occurrence of the problem. For whatever it’s worth, this problem did not occur before the MIDI upgrade was installed
2. The TOMS channel has a hum. It won’t be heard when the volume fader for that channel is turned down. It’s not particularly loud but is noticeable.
Otherwise it seems to be in fine condition as you can see from the photos. Has all of the original sound ROMs as far as I can tell. The MIDI input/output as well as MIDI sync work well. This particular DX could be very useful to someone looking to use it as a MIDI module
A paper DX manual is included and I believe there is a manual for the MIDI upgrade online. There is a cheat-sheet sticker on the top of the unit (see pics) that explains what menu options correspond to MIDI functions” Link
