Hi Ploughman,
After some more work on this case, I can also say that you can do it with only one macro and the track selection system. And the macro will only need one line :
TrackMute trk_sel {(valueOfReactionNamed(“TrackMute_trk” + $current_selected_track$) == 0) ? 1 : 0 }
This track takes the current state of the selected track and reverse to the other value… If the track mute state is 1 (muted), it put it at 0 (unmuted), and so on…
OK, that’s not direct, you first need to select the track and then push the macro button.
