Hi :)
It would be nice for there to be a graphical representation telling you that a bus is in now solo, once you solo a channel that feeds that bus.
TPIAW:
When you solo a channel, any bus that channel is routed to, should also show that it is in solo.
And vice-versa. When you solo a bus, any channel that is routed to that bus should also show that it is in solo.
Cheers.
