So, I just realized that FX Chains can be dropped into the FX bin like individual plugins, can be opened for editing like individual plugins, can be controlled from a control surface (unlike in the ProChannel) like individual plugins, but will not respond to X-Ray. It would be great if they did! I have arrived at a point, especially with Sonar2015 which auto-closes one FX window if you open another, where I my default action if I'm finished editing is to hit x (my preferred keyboard shortcut for X-Ray) and move on, knowing that every time I open a new FX window it clears the last one. Except if I'm using an FX Chain. Anyone else?
