DMX and DX EPROM Images

These files are exact binary images of the original Oberheim drum sound chips, suitable for making duplicate EPROMS. You may download these files for your own personal use.

I would like to make this collection of sounds more complete, so if you have an Oberheim DMX, DX or Stretch DX with sounds other than those listed here, and would like to contribute to this archive, please contact me by e-mail.

Thanks to Brad Kraft for supplying many of the DX sound images!

Download the files listed in the Download column and program them onto the type of EPROMs indicated. (In most web browsers, you can right-click or hold down the shift key while you click the link to bring up a "Save As" menu). To preview the sounds, click on the link in the WAV File column to play WAV file versions of the sounds. Note: The WAV files were converted directly from the binary EPROM files, and do not have any filtering or envelope effects which you would hear when listening to the audio output of the DMX.

Notes
Shorter sounds can be used on larger EPROMs by filling unused space in the EPROM with zeroes (silence). Single EPROM sounds can be used in a DMX or DX multi-EPROM cymbal voice by filling the unused EPROM sockets with "silent" EPROMs, filled entirely with zeroes. If you leave the unused sockets empty, there will be a lound thump at the end of the sound. You should be able to use your device programmer software to create such a silent EPROM (which is not the same as an erased EPROM, since the erased state of an EPROM is to have all byte locations filled with 0xFF). But for convenience, two silent bin files are listed at the end of this file.

Longer sounds on a smaller EPROM are possible, but the sound will be truncated and probably not sound very good.
