Increase The Functionality Of Analog Synths And Other Gear With The Korg SQ1 Step Sequencer

2 x 8 step sequencer. Connect any type of device and control it freely.

When the classic MS-20 analog synthesizer appeared in 1978, it had a trusted partner in the SQ-10 step sequencer. Now, after thirty years, the MS-20 has been reborn as the MS-20 mini, and the SQ-10 has evolved into the more modern SQ-1.

The SQ-1 is a compact step sequencer with 2 x 8 steps. It's wealth of connection jacks allows it to be connected to the MS-20 and a variety of other synthesizers. Vintage analog synths or the latest compact synths can be controlled from this single unit. You can also switch between a variety of synthesizer modes and use the step buttons to create performances overflowing with spontaneity, just as when using a volca unit.

Liberate yourself from the numerically-bound parameter editing that's typical on a DAW; you'll enjoy truly musical inspiration as you train your ears and concentrate on what your fingertips are doing. Don't miss the experience of music that's driven by your instinct.
