It would be nice to be able to hold shift and select multiple plugins to load. So, you hold shift, and click on what plug-ins you want and the order in which you click on them is the order in which they load (a little number would be displayed next to each plug-in you click signifying its order in the queue), and they load from the insert you click on and fill whatever empty insert spaces that follow. ex:
2.Empty <----- Load plugin(s): EQ1 (1), Compressor1 (2), EQ2 (3), Tube Emu (4)
Result would be:
6. Tube Emu
Maybe Cubase could prompt an option to swap previously loaded plugins (in this case ‘3.Distortion A’) or keep them.
This would also be great for loading multiply delay plugins into the same FX channel because you want to play around with a select few and decide which you like, or utilize a combination.
