The DX was a lighter version of the classic DMX drum machine. In fact its look, features and programming method are basically the same as the DMX. The DX has individual tuning knobs for the drum tones and an external trigger input. Its sounds are sampled recordings of actual instruments. Both drum machines have a number of human like feel effects such as a great swing function, rolls, flams and other weird time signatures and grooves. Best of all it's easy to operate. There are also 6 individual outputs like the DMX for easing studio use.
Introduced in 1983, the Oberheim DX was a slightly stripped down version of the DMX, available at a list price of US$1,395. The look and feel of the machine was similar to that of the DMX, but it only featured 18 sounds instead of 24; allowed for 6-sound polyphony instead of 8; had a 4-digit, 7-segment display instead of a 16-character alphanumeric display; and had fake plastic wood instead of walnut. Additionally, the voices were stored on EPROMs directly on the circuit board instead of removable voice cards. The Midi DX model added MIDI support from the factory. Later a newer model the Stretch DX was launched which expanded the possibilities even more.
