Back in 1979, this compact analog sequencer marked one of Oberheim's early forays into rhythmic control, designed to breathe life into their classic poly synths like the Two Voice or Four Voice by generating precise CV and Gate patterns.
At its core, it offers two parallel 8-step sequences, each with dual-concentric knobs for setting voltages across a full 4-octave range, perfect for driving SEM modules or other V/Oct compatible gear. You get independent routing—sequence one to one voice, sequence two to another—plus sample-and-hold with adjustable lag, keyboard transposition options, and a voltage-controllable internal clock for tempo tweaks, run/stop, and step advance. The desktop module is straightforward and rugged, with front-panel controls for everything and rear jacks for CV/Gate outputs, keeping it simple for hands-on tweaking without MIDI complexity.
Collectors and vintage enthusiasts prize its raw, no-frills analog charm for arpeggios, loops, and hypnotic patterns, though some note its limited steps and lack of memory make it a niche companion rather than a modern workhorse.
