Thanks for the info, definitely needed this.
Not sure if this is the case in older versions of Renoise but I just transferred a bunch of songs from mac to windows for 3.1.1 using this method and noticed one thing to add:
There are a number of tags related to each plugin in the XML files but only the tag seems to matter.
must match the exact name of the .dll file. (You DO NOT need to include .dll in the name though.)
and Don’t seem to have an effect on whether or not Renoise will find and load the correct VST. So you can leave them as they are.
Take this with a grain of salt because I haven’t done a ton of testing but obviously changing one text field instead of 3 for every problem VST is a lot faster.
