Mute toggle not working

[HadeNewell]

I am trying to bind a single button to toggle mute on an audio source. It successfully listens for the button, however the toggle does not work i.e press the button (note on), audio source gets mutes, release the button (note off), nothing happens, press the button again (note on), audio source gets unmuted, release the button (note off), nothing happens. If i select "Toggle Not On/Off Messages" then the audio source will toggle while I hold the button down, essentially a push to mute. This is not what I want.

We are using different devices and hence my experience may not apply to you. Just want to share that I got the mute toggle working.

1. I use Korg nanoKONTROL2 and the MUTE button can be a settle for Momentary, or Toggle. I set to Momentary
2. In obs-migi-mg. I map that action to "Toggle Source Mute".
   It works for me. Press once to MUTE, press once to UNMUTE.

(Only in the version 3) Separately, if you want the MUTE button on the controller to light up, you must create another mapping to send mute status change to the nanoKONTROL2
