How to Write wah pedal movements in TH2 ?

I find TH2 wah wah sounds quite useful. Most of the time I still use real Crybaby before audio interface though it is appealing to have an option to add or alter "footwork" performance after tracking. The "write" automation button does not seem to be working - I select it in TH2, it changes to "red", then play project and furiously move wah pedal with my mouse, I hear pretty decent wah efffect on my guitar track and this "automation" does not get recorded. Any idea?
Also is there a way to control TH2 wah with a real expression pedal?

I want to add that you can just use act to map to anything in the smart bar. It is helpful to know. This is how I did it before the blog was posted.

I just plugged mine in and used act initially. Then you click on the smart bar item to automate and move the pedal and they map. :-)

I may have some type instructions I wrote for another user at home. I'll give a look and post back.

Here's what I learned getting it to work... First, I like to record at 24 bit 88.2 and after following the instructions on this thread...

I am able to have 2 tracks not frozen at 88.2 24 bit with th2. This helps me.
 
Next, I run the midi out from my GR20 to my midi in on my m-audio fast track ultra.
 
I open X2, click P > Midi Devices and ensure the midi device is checked and click apply.
 
Next > Controllers/Surfaces > Yellow Star Button > Act Midi Controller Choice > In Port = Fast Track Ultra In > Out put = None > Act Checked > WAI unchecked > Apply.
 
OK to return to main screen
 
Utilities > Act Midi Controller 1 > This opens the Act Midi controller screen which will follow the control with the focus.
 
Next, Add and audio track to your project and TH2 to the FX Bin. I had trouble using it through an FX Chain in the Pro Channel. (you can drag an FX Chain to the bin and extract it). Double click the TH2 to open it.
 
In the TH2 screen, add a volume pedal or any other thing to the signal chain. Drag the volume pedal itself to one of the array of smart buttons/switches/nobs at the bottom of the window... this will then enable you to assign a control from the pedal to that button or nob.
 
Now > Bring the focus from the TH2 window to the Act Midi Controller Window. The Act Enabled Device (see bottom left of this window) should say TH2-64. The array of smart controls should be across the top row in blue.
 
Click the smart control you want to automate with your pedal on the bottom half so it says 'midi learn' and then move the pedal. If it is working properly, it should immediately begin to read the value from the pedal and apply it to the smart nob... so on the window for the TH2 you will actually see the pedal rising and falling as you move your real life pedal.

I never tried with my Pod XT and foot controller. I just play the part, add the wah effect and create envelopes. It works pretty well but is time consuming. The good part is it's ver exacting.

This is the part that doesn't work or I don't understand what I should be doing.

If your device has MIDI out or USB/MIDI drivers then it should work, though mine isn't working at the moment.
 
Post #9 is the list though it's not as clear as it could be.

So Digitech says: "The R255 cannot be used as a midi controller for a DAW."

In an effort to help with this, I'm posting a video that walks you through how to add the controller and then wire it up using ACT to a parameter that you wish to control, like the WAH filter in TH2.

Thanks, for the video, most helpful !
