How to assign a midi keyboard fader to audio track FX param?

Hi. I use cubase 5.
I know how to assign virtual instrument parameter to a midi CC.
I can always assign midi keyboard to a virtual synthesizer track and determine experimentally what midi fader is corresponds to a virtual synthesizer rotary knob.
But I can’t even assign my keyboard to an audio track effect.
How to assign midi fader fader to the “Tone Booster” tone parameter for example?
Thank you.

The learn function in either Quick Controls or the Generic Remote.

Thanks a lot! I didn’t know that. Quick Controls is really convenient feature :smiley:
