Hi I had an issue with Pitch settings after using Open Track and I could not find a solution than unistall the programm.
Maybe there is an easy fix but believe me I remember searching for days with no solution or suggested steps.
In details:
I had installed the portable version, so no installation files, the program was in a folder. I initialized the program and set the axes, curves etc. All good (more or less*)
When I bought a bigger monitor I decided to eliminate the tracking (*I used it superficially with the cam and facial recognition without great satisfaction).
However even deleting the folder the pitch still not working...desperate I searched in Github, reddit for nights...and then a voice told me "but it could be a file installed in the AC folder that emulates or replaces the original file and deleting only the folder it is not deleted... try to install the .exe version which probably when uninstalling also deletes the "replicant" file".
Yes!!! after days yelling against OpenTrack the Pitch was back !!
Test it, this is my experiene.
