The Oberheim DSX is a pre-MIDI digital polyphonic sequencer. It operates using a proprietary parallel bus and was designed for use with the OB-X, OB-SX, OB-Xa and OB-8. Connection was via a heavy 1:1 cable, which plugged from the host DSX to the target synthesizer using a rear DB-37 connector. The DSX is capable of driving up to 16 voices concurrently. Sequences are stored in internal memory after power-off using static RAM which remains powered up from an internal NiCad battery.

The combination of Oberheim DSX, Oberheim DMX and either OB-8 or OB-Xa were marketed as the "Oberheim System".

The DSX is capable of storing and sequencing over 6,000 events, over 10 songs of 10 patterns each.^[1] The DSX is also capable of also driving traditional analog synthesizers via its 8-channel CV/Gate interface. It's also possible to drive the DSX via an external clock.
