Problem with toggle bindings in Background Rack

[twaw]

I recently switched to C4 from C3, but after re-reading the Guide on bindings I can’t get this one to work. It was good on C3.
I have a custom button called TUNER that when pressed, suspends my Master output (silences it), Shows the GUI on my Tuner plugin, and unsuspends the Tuner. The next press just reverses all that, toggling it. When I use the Test button for each binding it works. When I close the binding dialog and try the button, no midi signal gets to that Binding group at all, and nothing works. What am I doing wrong? I can’t seem to get any toggling to work. It’s probably something simple.

I didn’t bother to show the Master Rack binding dialog, it’s essentially the same thing. Thanks!

Set the Source Event to Controller(No Edge Button) and you will get the toggle option in the mapping area.

Thanks, Dave. I’d tried that, still doesn’t work. SOLUTION: I changed the button itself… in C4 it now has values for Press and Release of the button. After moving to C4 the values defaulted to 0 for both. So I set Pressed value to 127, kept Release at 0, and viola… it works. Thanks for your help though, it got me thinking it must be something other than the bindings.
