I run my show with a main list on fader 10, with various things on other faders.
I run through the main list with the main playback button.
Sometimes I need to hold down the Choose on a different master to adjust something, but don't want to actually choose it. In the heat of the moment it is very easy to forget to re-choose the main list.
It seems to me it would make sense for the Choose button to select if it is tapped, but not if it is held for a duration of time.
I can then adjust rates etc on other masters without losing the main list from the master playback.
Hope that makes sense.
Leggy.
