Returns Policy



It was 1978, the Korg MS-20 analog synth had just launched and became popular almost overnight. It's partner in crime at the time was the SQ-10 to add step-sequencing capability to the mix. More than 30 years on, Korg have evolved the original into the modern and very capable SQ-1.

The SQ-1 supports the Hz/V standard as it was initially designed to work with the MS-20. It goes without saying the V/Oct standard is also supported, and the voltage level of the CV output can be specified to suit the device you wish to connect. This versatility means you have much more choice over the range of equipment you can control with the SQ-1. In total, the SQ-1 provides you with two CV/GATE OUT channels, MIDI OUT and USB MIDI, littleBits out (to connect to the Electronics Inc littleBits synth, plus a SYNC IN/OUT channel meaning you can also connect to a monotribe or any of the Volca series.

Stepping out

There are 2 channels available to you on the Korg SQ-1 (A and B). This opens you up to much variety thanks to the selectable modes. You can have channel B follow channel A to provide a 16-step sequence, ignore the order and make the steps play randomly, operate independently of each other use A and B to control different parameters for more complex creations.

Built to last

The Korg SQ-1 is a unit that you will want to take out on the road with you; and the build quality ensures that you can. Sheet metal delivers a sense of classic solidarity that will appeal to musicians old and new.

The SQ-1 can be powered from USB or by 2 x AA batteries, no bulky adapters to carry around, just plug in and start sequencing!
