I have tried that but no success :
delete : patches.bin
put the new patches.ini in /pt folder
run PTPA
exit PTPA

nothing is new : in the "patch dialog" menu , PT shows again the same list of instruments : GM list, GM drums ... but nothing about my XP30 instruments.
also : PTPA did not rebuild any new patches.bin file !

Could You please try yourself the process on your computer and see what hapens ? Do any of you use an external midi synth with new patches list ?

The only mistake I can imagine is :
I have installed PT in folder C:/Program files/pt , but not in C:/Program files (x86)/pt . And my windows is w7x64. tired
