Basically all you need to do is:
Install PD Extended
Install MIDIYOKE
Open the PD source file
Make sure PD is listening on the same port that touchOSC is sending from.
Open up Tyrell in host and right click the parameter, select midi learn, and just move the parameter that coincides with the one in the vst.
I don't have a Mac, so I'm assuming all you would need is OSCulator.
It's not perfect.. some alignments are off and a couple labels are cutoff, but it gets the job done.
