The Oberheim DSX is a 9-track digital sequencer equipped with the Oberheim Serial Buss for connecting with the company's OB-Xa or OB-8 synthesizers and DMX drum machine. Connected and used together, Oberheim marketed these products as "The System". In addition to the Oberheim Serial Buss, the DSX has an 8-channel CV/Gate interface for sequencing traditional analog synthesizers.

The DSX is capable of storing and sequencing over 6,000 events, over 10 songs of 10 patterns each.[1] 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 DSX equipped with the Oberheim Serial Buss, a pre-MIDI proprietary parallel bus designed to directly interface the DSX with Oberheim's OB-Xa or OB-8 synthesizers along with their DMX drum machine. 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 combination of the DSX, DMX and either OB-Xa or OB-8 were marketed by Oberheim as "The System".[2]
