Well I thought I had this figured out because I can successfully toggle the state of my Goodwood Audio Wet Dry Wet junction box’s dry mute via a button on the MC6 Pro. However, it can only toggle. Using “Engage” or “Disengage” either does nothing or toggles once (from whatever state it was already in). So there’s no way to know that pressing the button is turning it off or on. To make things worse, it seems every time I power the board off and back on again, the dry mute toggles state when it powers back on. So I really never know how to get the device in sync with the toggle button on the MC6 Pro.
What kind of footswitch does it normally work with (latching or momentary? one footswitch or two?) and what is its normal behavior? If it takes a latching footswitch or a dual-footswitch, you have a chance of being able to assign it a specific state. If it just takes a momentary external footswitch and toggles when pressed, there’s probably no way to set it a specific way.
That said, if the device always powers on to one state, then you could power ON both devices together, set the MC6 to that state, and then the MC6 would presumably be sync’d with it as long as the changes were only happening on the MC6.
I chatted back and forth with Goodwood Audio on this, and we couldn’t find a simple solution.
It’s a momentary relay, normally open.
If I pull the plug on the WDW (the Goodwood junction box) only, it powers on in the same state it was in before I unplugged it. Similarly, pulling the plug on the MC6 Pro only causes the dry mute on the WDW to “reset” to the same state. In other words, the relay clicks when the MC6 pro powers on, and the LED will quickly toggle states, then toggle back to its original state. But when I pull the plug on my power supply, affecting both units at once, the WDW toggles the dry mute to the opposite state from what it was in before powering off. This occurs before the MC6 Pro is finished booting up, but I think the MC6 Pro is triggering it because it doesn’t toggle if I unplug the TRS cable from the MC6’s relay port. Is there something happening with the relays during the bootup sequence?
