Question

MIDI Control Jaw Movement

This seems like it should be a fairly common thing, but I can't find any info on it.  I know that CA accepts MIDI inputs, but I haven't found anything on how to set up a jaw / mouth animation driven by the intensity of the MIDI button press.  I'd like to be able to control my character's mouth similar to a physical puppet where you operate the mouth as you talk (or in my case, try to match the pre-recorded audio by tapping along).  Why not just use the Nutcracker Jaw and open/close my mouth?  Well, I find that that's actually pretty difficult to do, as well as tiring/painful on my face muscles (anybody else get "CA Neck" after a day of rigging and testing the head movements of a character?).  My fingers are much better at quick up/down movements.

Anyone have ideas for me?

I'm not good at English.
I'm using translation software, but you may not understand exactly what you posted.

Unfortunately, the current Adobe Character Animator does not support MIDI velocity.

The solution is
1 Assign the maximum movement value of "Nutcracker Jaw" to the controller.

2 Assign it to the slider of the MIDI controller(Example: Pitch bend wheel
Modulation wheel).

3 You can adjust the opening degree of the mouth with the value of the slider.

Thank you.

    Thank you so much, @k_oshiro !  I did not realize that velocity was not supported.  That's unfortunate, but I'll put in a feature request.  That's a good trick using the slider to control maximum movement of the nutcracker jaw.  I'm borrowing a MIDI device today, so I'll see if this could work for now.
