VSTWrapperBuilder is a tool designed to get rid of common issues with VST plug-ins:
Giant menu with VST Shell. Using such thing inside Nuendo or Cubase is a nightmare. Here the solution: Use VSTWrapperBuilder to extract all plugins from the shell and organize them properly on your hard drive. You can define some rules to specify where a given effect must belong to.
Old plugins require the audio buffer to be cleared by the host. With recent hosts this is not done so your famous old plugin can no longer be used. The solution is simple: generate a wrapper with VSTWrapperBuilder checking the column "Old" and that's all. It will work. The wrapper will fill the audio buffer properly.
Some VST Hosts don't send effSetSpeakerArrangement to surround plugins. Because of that, they acting in mono most of the time. The solution is also simple: generate a wrapper with VSTWrapperBuilder checking the column "Surround" and that's all. The plugin will receive automatically a 5.1 configuration. Of course you have to use it on a 5.1 track.
You know what? It would be nice to add a feature which provides a bank/patch management for VST plugins which don't provide it. And some hosts don't resolve correctly the problem. So in such cases... it remains a nightmare for these users.
The versions 2.0 and 2.1 from your downloads page seem to be for a 32-bit application. (Says 'VSTWrapperBuilder 32-bits v2.1' at the top of the installed application. Is there no 64-bit version? The 32-bit version complains when trying to load a 64-bit plugin that it is not a 'valid 32-bit plugin'. :-) Where could I get the 64-bit version from?
The confusion came in because often an installer is either for 32 or 64-bit or gives you the option to install a 32 or 64-bit application during the process. When the install got to the last tab where it gave the option to launch the application, there was no choice neither. I run it from there and it started the 32-bit version. (At least I think - from a tired memory - that that was the sequence of events). So I think I just assumed that was the only thing that was installed....
But, as you said, they are both there and working fine. Thank you.
