hey all!!! just to clear this up. I am covering it in the video im doing today for it. it is indeed momentary on 1 side and not momentary on the other./
you have a couple of options.
the reason I use this switch is so if I push down on it it triggers the adsr momentarily, but if I switch it up it latches the envelope generator on, meaning if you turn up the sustain for instance it is just a solid voltage.
if you cant find the funky (on) off on then not to fear, if you aint fussed about the latching feature which isn’t that vital anyway just go for a completely momentary switch
