this....... basically just open the folder in the corner where it says thor patches pull the drop down out and it will say all patches or instruments or whatever and select your sound as normal.No, the easiest, most simplest is to just go into the Thor patch, and change it to your desired Malstrom patch and it will notify you that "There are no Thor Patches in this folder but ## other instruments.", just press OK and it'll show you the rest and once you find your patch it will automatically switch them out.
I'm not sure if this works with 4 if you using 4 or below but, I know this works with 5.0+ for sure.
