if you have the MixConsole divided in 2 or 3 zones and the right or left zone contain enough tracks to fill the whole MixConsole, then the scroll bar won’t work to scroll through them, as it applies to the main (i.e. central) zone only. This is due to having one scroll-bar, which can operate only one of the zones (the main), I’d guess the only way to solve this would be to implement more scroll-bars when more than one zone exist, with each of them controlling one zone (and forcing each zone to have a fixed amount of visible tracks). I don’t know if this is currently feasible.
Is this what you mean? And did I understand correctly?
If the right zone has so many channels, wouldn’t it be worth assigning them to, say, MixConsole 2 and hide them from console 1?
