Thank you for viewing! This is the KORG analog step sequencer "SQ-1". It has a compact body with a variety of connection terminals, making it ideal for controlling analog synths like the MS-20, Volca series, and Eurorack (modular synths). It's also useful for DAW-less jam sessions. 【Condition】 ・Operation: Operation confirmed with batteries and USB bus power. ・Each knob and step button responds well. ・Appearance: No noticeable scratches, it's clean. ・Battery compartment: No leaks or rust. 【Included Items】 ・Main unit ・MIDI conversion cable ・Instruction manual ・Original box (※Batteries are not included) 【Shipping】 The original box will be wrapped in bubble wrap and shipped via "Rakuraku Mercari Bin (Takkyubin Compact)". It supports both Hz/V and V/Oct standards, allowing it to be used with a wide range of synths, from older models to the latest modular synths. I am selling it to organize my equipment. #KORG #Korg #SQ1 #Sequencer #AnalogSynth #ModularSynth #Eurorack #MS20 #Volca #DTM
