Oberheim DMX - Drum Machine

via this auction

"Note that this a DMX, not a DX. The main difference (and the reason why the DMX is a classic, while the DX isn't) is that there's a Curtis analogue filter for EVERY sample card (the cards fill the left half of the DMX's innards, see pics). This rounds off the punchy 12-bit samples and, well, makes it sound the way it does. Which is punchy as hell... There are individual outs for each sound, too, so recording options are super-flexible (e.g., getting a dedicated reverb on the snare)."

Update via Synth Snight in the comments: "I'm not sure this is true. These schematics show a 3320 in the toms but I don't think there on every voice card.

Update via Kerry in the comments: "good ol' ebay hyperbole. actually, if I look closely at his picture of the voice cards, I see 1554B cards, which do NOT have even the sockets for the CEM3320 analog filter, the 1667's have the CEM analog filter (I'm looking at my DMX opened up right now) but I don't see any of those cards in that ebay unit!"

  1. I'm not sure this is true. These schematics show a 3320 in the toms but I don't think there on every voice card.
