Pro-C 3 access to instance list
After trying Pro-C 3, I'm surprised that it can't open the plugin instance list itself. It feels weird to need a null instance of Pro-Q 4 to access a bunch of different compressors at once. Hopefully this can be changed in a future update. Until then, I think I'm gonna wait to upgrade.

Hi Karl,
For now the instance list can only be accessed from within Pro-Q 4. The plug-in intercommunication requires quite some data, and it can get messy very quickly if multiple plug-ins need to access all that information and control all other plug-ins. So for the time being the instance list is really a Pro-Q 4 feature only. Hope you understand.
