Pedalboard in Garageband

Hi,

I'm making songs with Garageband, and I just wondered if I can change or control pedal's levels while recording in Garageband.

For example, Wah Pedal is, as you may know, something that we adjust the strength of treading and change the sounds while recordings, but is it possible to do the same thing with Pedalboard?

I tried to do this but failed (the change is not reflected to the recording), so I posted this question.

Thanks for reading 😉

garagebandのPedalboardで、録音中にペダルの踏み加減等（wahなど）を調整し、それを録音に反映させることは可能でしょうか？
