+1 on the show/hide track
I also get reasonably regular crashes in Eucon - usually releasing channels - either on close or when moving tracks around. In fact it’s about the only crash I get in cubase/nuendo and happens when I’m not actually using the Avid Control App.
The crash is actually in the AVID eucon dll not the Steinberg one - just disappears without a .dmp file- if you look in the application log (windows) you can see where it occurred.
the mute VCA track bug needs fixing - controlling mute status of a VCA master channel over EUCON ? Lots of threads about this: (while Steinberg are doing that they could fix the whole VCA fiasco)
