This has been discussed in another thread.
The only way to put vst3 plugins into your own order / folder is to hack the plugin files with a Hex editor such as WinHex. why Steinberg has done this to its users is just bewildering. Steinberg has commented on this over a year ago that it is indeed unacceptable for users to need to resort to this but Steinberg has since done…nothing about it. Big Ups.
for vst2 plugins you can re-name and re-order the .dll files into file folders yourself, assuming that this does not break the .dll plugin links to its other related data such as presets or data sounds. But this is far from an elegant solution and ideally it should be made possible within Cubase…why this is not possible in either Plugin Information or Mediabay without needed to resort to moving .dll files and potentially upsetting plugin installations causes many users to shake their heads in dispair.
Do Steinberg not use their own software? how is this problem not frustrating to the programmers in Steinberg also? i guess its not as frustrating as your DAW crashing on exit every time… sigh
