One thing I keep hitting up against with Cantabile is where something has state-driven behaviour, but I want to reset its value in all states to some common starting point.
An example from real use: I tend to have state behaviour enabled on the rack faders in songs, so that different parts of songs can have different rack levels. On one occasion I decided to change the sound of one of my racks for the song, which meant rethinking its levels throughout the song, as it was quite a bit louder. What I wanted to do was set a uniform level for the rack for the whole song, and make tweaks where necessary. I had to disable state behaviour on the fader and then scan through every song state in order to pick up the new baseline value, and then re-enable state behaviour.
I also often have situations where I change the routing in a rack, for example add a new effects plugin in parallel with another, and want this to be applied for all rack states, while still having state behaviour enabled so I can override it where necessary.
It would have been really nice to have a right-click command on the item in question and choose “Copy value to all states”, without needing to use the workaround of disabling state behaviour, scanning through all states, then re-enabling state behaviour.
