was just messing around with my MS20 desktop and came up with a cool way to get it to continuously play a note without holding down the red "Trig SW" button by hand. I plugged a sustain pedal into the "Trig In" jack directly above the "White Noise" jack. That opens the gate when you step on the sustain pedal, BUT if you have a sustain pedal like mine that allows you to switch the polarity to closed by default instead of open, the MS20 will play the sustained note indefinitely without having to engage the pedal or hold the Trig SW button by hand - which I love to do as it frees up my hands to twist and play with other parameters
