Korg SQ-1 - CV Sequencer & Sync Box

Korg SQ-1 step sequencer for driving analog, modular, and CV/Gate gear. 16 steps arranged as two rows (channels A and B), playable as two independent 8-step sequences or a single 16-step sequence. Sequencer modes include Gate On/Off, Active Step, Slide, and Step Jump, with selectable pitch modes (Linear, Minor, Major, Chromatic).

Connections (all on the top panel): two independent CV outputs (CV-A and CV-B) with dedicated Gate jacks, switchable CV ranges of 1V / 2V / 5V (V/Oct) and 8V (Hz/V) - so it works with both modern V/Oct gear and older Korg Hz/V synths - Sync In/Out, MIDI Out (mini stereo jack), a littleBits output, and USB (Type B, USB-MIDI). Pairs well with Eurorack, the Korg Volca series, MS-20, littleBits, and MIDI instruments. Powered by 2× AA batteries (about 5 hours on alkalines) or USB.

Compact desktop size: 193 × 84 × 63 mm (7.60 × 3.31 × 2.48 in), 641 g (1.41 lb).

Condition - excellent. Black anodized body is clean with crisp white panel printing. All white step buttons, the translucent step knobs, and the mode dial are present and unmarked; status LEDs and jacks are clean with no corrosion. No visible scratches, scuffs, or wear. Tested and working — both channels sequence and output CV/gate correctly.
