Ah yes ... that's why I posted in the feature wishlist. For Ableton to do this, it seems not a biggie. But for anyone else this problem can't be solved. Not with M4L, not with Clyphx, not with anything else. The solution has to come from the code inside Live. Thanks anyway!
You see, the problem is: when I launch a scene, in my livesets I start a whole new pattern / song.
I have 8 drumtracks and 8 synthtracks, but when I start the new song not everything needs to start as I like to build up the song gradually (playing LIVE you know

). I can't remember and/or I'm not quick enough to start only the tracks I need every time. Before the switch I sometimes have my hands full twisting effects or playing something to make the transition. I
could make a new scene just for the "intro" of my pattern but that doubles the need of scenes for me - for every new scene (pattern) I need to make a special "intro" scene.
For everyone who has ever worked with some kind of groovebox this is a big aspect of the live performance. You go to the next song, but when launching only certain tracks start while the others are muted but ready to start.
