Thanks for posting this, I will be attempting the same thing soon when I buy an expression pedal. Meanwhile, I was wondering about using the slider on either my CMC-TP or CMC-CH to do it (using my finger instead of the mouse to work the sweep to record wah automation).
Would I follow the same steps to assign one of those sliders to the VST Amprack wah? Will the CMC sliders utilize MIDI LEARN?
Thanks in advance.
