This item that’s one of MS Extension Module series will convert gate signal from negative gate (High to Low) to positive gate (Low to High). You can connect some equipment that have different gate type for each other.
This not only MS-20 mini, or as part of another modular, and can also be used in combination with other stand-alone type synthesizer with a CV and gate
Let MS-20’s gates high!

This equipment is intended as using with not only MS-20 mini but also a part of modular or stand alone synth that have Gate inputs. Its input impedance is designed high enough to be able to receive more high impedance output such as Artria’s “Beatstep”‘s.
Using this converter as buffer, you may get more chance to drive other equipments from “Betastep”.
