found that in the manual but it throws an error:
same for 'unmutetracks.'Your batch command of MuteTracks was not recognized.
i did find that MuteAllTracks and UnmuteAllTracks both worked, as did TrackMute. problem with TrackMute, though, is that it is a toggle and requires focus to be set. i was hoping for a simple command to set the state either on or off.
second, somewhere in the manual i found a note that i could comment in macros with the # symbol but that also threw up an error.
editing my post before i even am posting it, here. found that i can use 'set track,' turning all options off except the 'mute' checkboxes. still new enough at this that i'm confused as to why i have to check two (both) boxes to have the mute apply. it seems that selecting both checkboxes selects 'mute' and selecting only the left checkbox selects 'unmute.' confusing but seems to work.
