I am finding anomolies when using the mute, both in the mixer and in the activity bar of the track list in the project zone. I think this is correct.
Sometimes, when I mute a track, the activity is visually deleted (I.e. no visiual). Sometimes when muting a track there is still MIDI visual action. This messes with your head when you are dealing with multipe tracks.
Here is an example. All of the tracks are muted. All have events that are -playing Some show action, (highlighted in white in the mixer) most dont.
