I may have the wiring on my TRS cable wrong though, because the tap to control the mute doesn’t even work. I click once and nothing happens, click again and then it toggles the summing. Not sure what’s going on - I may reach out to the guys at Goodwood and see if they have inputThat doesn’t do it, the hold isn’t a momentary thing. Tapping it will mute/unmute and then after a two second hold, it toggles between stereo and mono sum. I wouldn’t want it to revert after two seconds but rather complete a separate action after the two second hold. Like an IA hold function in a sense. But I tried doing on/off for function 1 with a tap and then on/off for function 2 with a hold and that didn’t work
