Rather than the commonly used V/Oct standard, the CV design of the MS-20 always used the Hz/V standard that provides excellent pitch stability limiting the step sequencers that are able to correctly control the MS-20. As a descendant of the SQ-10, the SQ-1 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.
