The Shock Electronix ESQU-One Step Sequencer is our Eurorack conversion of the super compact and highly versatile Korg SQ-1 Step Sequencer.


As standard, the Korg SQ-1 is a compact step sequencer with 2 x 8 steps. It's wealth of connection jacks allows it to be integrated with a Eurorack System, 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.


As a descendant of the SQ-10, and just like the SQ-1, the EsQu-One supports the Hz/V standard, enabling it to perfectly control the MS-20 or MS-20 mini. It goes without saying the V/Oct standard is also supported, and the voltage level of the CV output (*) and polarity of the GATE output can be specified as appropriate for the device you've connected. This versatility will enable you to control a wide variety of other synthesizers as well.


* V/Oct supported for 1V, 2V, and 5V; Hz/V supported for 8V.


Just like the SQ-1, the EsQu-One provides two CV/GATE OUT channels, the standard MIDI OUT and USB MIDI, littleBits out (to connect to the littleBits synth kit by littleBits Electronics Inc.), plus the SYNC IN/OUT channel that allows you to connect to the volca series and monotribe. In addition to this, we’ve designed the EsQu-One with an added 4 rows of multiples, and easy access to the USB port at the bottom.
