Hi,

I browsed quite a lot (maybe not enough ?) but I can't find the sysex 
commands to mute / unmute a track

I would like to control un/muteing different tracks in one go on one 
midi channel of my RS7000.

Seems this was allready discussed but I did not find any answers.

Thanks a lot.

An example would be nice : how to mute track 1 and unmute track 2 in 
Sysex
