EdSki hi Ed, I can see what you want and it makes some sense to a point, you are obviously running multitrack and want to automatically control the mute/unmute of any track at any time using the lyrics editor by writing in simple commands.
My need and request was made ages ago regarding this need but I look at it differently, if I am forced to use complicated programming that takes time and effort to do this in the editor I might as well just edit my tracks in the Daw to create the effect I want and keep ST3 simple, but what I want is immediate control of MUTES and the ability to SOLO a track on the run this then gives us all a lot of power on stage to create the atmosphere as needed.
I don’t think it’s also a bad idea to easily place a mute/unmute or solo command in the lyrics editor but it needs to be very simple and quick to program, otherwise you are just asking for more time wasting when it could be easily done in the DAW.
Good luck
