This is what I was looking for! 
I'll try it shortly and am planning to report back here.
Is it possible to solo multiple streams at a time too? Didn't know, could you ellaborate a bit or point me to some documentation or example? I found a fairly recent post of you here: https://club.tidalcycles.org/t/mute-unmute-via-osc-midi. But unfortunately the mentioned page has been moved .
Thanks a lot! Your help is much appreciated.
Btw, (un)muting and (un)soloing is big fun when playing live.
