You may have found this, but just in case.. Each of the VC8 instruments, along with Analog Lab - have assignable 'Macros'. These can be found by clicking the Gear icon on the GUI and selecting the Macro tab. There, you will see the four default Macros. Brightness, Timbre, Time, and Movement. Each of these controls can have zero to many assigned controls on the instruments. It is easy to see, if you pull open a patch, click on edit for the instrument and see how the sound designer mapped controls to these macros. With these mapped to various knobs, switches, controls on the instrument - you can manipulate all those controls at the same time, by moving just the Macro knob they have been assigned to, in the GUI. You can then.. click the MIDI tab (next to the Macro tab you are editing on) - and assign a single CC to each of the four Macros. Now.. you have multiple controls mapped to a single CC. There are videos which show this, but once you have mapped out an instrument this way - it's pretty simple.
