The time to map them up in a way that makes sense to you.Hardware CC controllers to map to the controls in the virtual instrument.Virtual instruments that support MIDI CC messages to make performance changes.The other faders change all kinds of things like articulation mode (e.g., change to tremolo and change the speed of the tremolo) and reverb levels, etc. So he can call up french horns, hit a chord with his right hand, and then use his left to grab a fader and perform a crescendo on the horns.

He has a control surface with several faders on it, and each fader is mapped to a different MIDI control message that changes a performance parameter on the virtual instrument.


I just watched a series of videos of film composer Hans Zimmer who mocks up all his soundtracks using software and virtual instruments so the directors can hear what it's going to sound like before they record it with a real orchestra or other musicians.
