Oberheim Drum Machines were not velocity sensitive;like the LM-1 different levels of the sample were made available by triggering a different "note".
They didn't actually become notes until MIDI was added, but that's how it was done.
MIDI was made available for the DMX and DX around the same time the Akai S900 took off, and both machines were soon discontinued. Shame I say.
The pure samples are only part of the story, each voice being enveloped in various ways by hardware implementation on the 8 voice cards, each having a CEM filter chip and DtoA.
Pitch variation with envelope was used on the tom cards, and an envelope related closing filter frequency on snare etc to reduce noise possibly. If you were keen you could "damp" the lower pitch tom to be shorter than the hi tom derived from the same sample. A soldering iron and resistors and capacitors were required, but still, heady stuff.
In this way a single sample, treated differently could fool even the professional listener into thinking they were hearing multiple samples.
When the Prommer appeared it was possible to load the Prommer with any chips you couldn't fit inside the DMX and trigger them from MIDI, but the sounds didn't match, without a voice card.
My expensive solution was multiple DMXs and voice cards. Couldn't afford to keep them, though I did get left with many chips and voice cards.
It does take a long time to sample these, and obviously once you choose a format, you narrow your choices.
Eventually I chose Akai S6000, and have transferred sounds from tape transfers via my DAW into wavs for the S6000.
Some years have passed since I began, and no I don't want to donate the result of all that effort for free, cruel as that may sound.
There is a DMX to WAV program and the BIN files are out on the internet, possibly here in the files section.
An old PC is required to work this trick I suspect. None of the voice card activity would be included of course.

RE: [oberheim] Oberheim DX
I've noticed that the X series drum machines by Oberheim are one of the rare classic drum machine sounds not found in sound font files or SFZ format sound maps. That'd be kind of cool, but it'd take someone recording each sound. (Were they velocity sensitive
)
