Oberheim Prommer

Oberheim Prommer Image

The Prommer is a device that burns EPROM chips for use in the Oberheim DMX Drum Machines. In effect the Prommer allows you to create or sample some sounds of your own for use with the DMX or other similar vintage drum machine like Sequential's Drumtraks. The Prommer is monophonic, 8-bit and with limited edit-ability and sampling.

Editing of samples include simple attack, decay, reverse, ring-mod, stretch/squash and other digital bit manipulation. It can send all samples as a MIDI dump to software editors such as WaveLab, so it is possible to edit and then send the samples back to the prommer to burn your custom EPROMs. Of course any modern-day sampler will blow this classic away. But the Prommer was a novel add-on to further enhance the creative use of HipHop's original beat machine, the DMX.

I have one of these machines in mint condition (since at the time the battery gave out
after about a month of light use). I don't have the original eproms but did successfully record my voice onto one at the time producing nice warm 8 bit samples that had alot of prescence in the recording of that time. It also played back drum sounds from an eprom included in the box. It still switches on but then says check battery so it won't function without the lithium disc battery which is probably inexpensive. I got it from Soho Soundhouse in London back in 1988 for 150 pounds. Quite the bargain!

I used one of these to burn custom kits on 32k chips for my Sequential Tom and Drumtrax, a DX, and a midi modded Drumulator.
Top gizmo. 2 whole seconds of 8bit audio data!
