Oberheim DMX 8-Voice Drum Machine
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"The Oberheim DMX is a classic digital drum machine introduced in 1981 by Oberheim Electronics. It became one of the most iconic drum machines of the early 1980s, particularly influential in hip-hop, electro, and pop music
🔧 Key Features:
12-bit digital samples: The DMX used actual sampled drum sounds stored in EPROM chips, giving it a realistic, punchy character that distinguished it from analog drum machines like the Roland TR-808.
Sounds: It included individual samples for kick, snare, hi-hats, toms, cymbals, claps, cowbell, etc. The samples could be swapped out using different EPROMs.
8-voice polyphony: You could play up to 8 drum sounds at once.
Individual outputs: Each drum sound had its own output jack, allowing for separate processing and mixing.
Swing and quantization: The DMX had adjustable swing, making its grooves feel more human.
Tight MIDI sync and clocking: It could sync with other gear via MIDI (on later models), DIN sync, or analog clock pulses.
Sequencing: Patterns and songs could be programmed in step or real-time mode, with memory for multiple patterns and songs.
🎧 Sound Character:
Punchy and dry, with a distinctive ’80s sheen.
The snare and clap are especially famous—used heavily in early rap and electro.
It had a more realistic, “studio drummer” feel than analog machines, making it ideal for producers aiming for a more polished sound
This unit has a toggle and button on top and button which we are not sure of the function. Never used it."
