I "Make Simlar" because I need a distinct new set of controls. I'm copying VG99 Channel A controls to paste them as Channel B controls, same function, but different signal path in the VG99.
So...to exapand a little....
If a Panel was a container and a panel could be visible / invisible according to the value of a super control, we could create some really dynamic templates. Of course, hiding a panel would hide the controls which it contains.
With this feature we could have a pick list which provides a selection of modulation effects. Depending on which modulation effect was selected, we would display a panel with an appropriate set of controls for that effect, and hide other panels.
The VG99 has a MODULATION 1 and MODULATION 2 and you get to pick they are a Chorus, Flanger, etc. So if you pick Chorus for Modulation 1, you need a set of controls to show that are appropriate for Chorus. Same applies if it was a Pitch Shifter, which would need completely different set of controls. This is why panels as containers, and having them go visible and invisible would be a massive benefit and enable very dynamic layouts to exist.
