I had this note in Support Corner, but maybe better chance of reaching Ableton eyes here.
how is Solo button supposed to work with Group tracks?
In Live 8.04's manual it says about Group Tracks:
"In Session View, slots in Group Tracks have launch and stop buttons whenever at least one
clip is available in a given scene. Launching or stopping this button has the same effect
as launching or stopping all contained clips."
So should Solo work the same way? Enabling/Disabling Group's Solo button would enable/disable Solo button of all contained tracks. Now it seems to treat contained tracks the same way as tracks outside the group. Which is totally different idea than how launch/stop works.
