Korg SQ-1

Korg SQ-1 is a two-channel step sequencer designed for use with Korg's Volca and MS-20 synthesizers. It has been used by a variety of artists, including Aphex Twin, Flying Lotus, and Four Tet.

The Korg SQ-1 works by allowing users to program a sequence of notes and rhythms that can be played back in a loop. It features eight knobs and eight buttons that can be used to control the tempo, pitch, and other parameters of the sequence. Additionally, it has two CV/Gate outputs that can be used to control external synthesizers and other devices. The SQ-1 also has a built-in arpeggiator and a shuffle mode for creating more complex patterns.
