hockeyjx's approach is one I've used before to record the Wha in GuitarRig.  Simply enable record on the MIDI track that you're using to feed MIDI commands to GuitarRig.  Just remember afterwords that that MIDI track is needed for the GuitarRig track (I once deleted the MIDI track and lost the wha movement).  With this approach you are recording two tracks at once: the audio with the guitar signal and the MIDI with the foot controller movements.

Mine is on the same track... I think it is how you set it up... 

I don't remember having two tracks, but I will look tonight if I can.

 

Hi Forum, many thanks for your answers!!! I found out, that I have no problems if I open a new Projekt. Now I have to discover what´s different in that project I tryed it before.
