Audio Plugin importation in Protools10 all black window.

1 view (last 30 days)
Audio plugin creation from audio system toolbox works well. No issues with DAWs interworking (eg Ableton), except Protools. Does anybody know why Protools10 (32bits) imports the generated vst with plugin´s windows all black? Seems something related with video card, but only happens with the Audio System Toobox´s vst. System used is WIN7. Thanks Pablo

Hi Pablo,
I work at MathWorks so I thought I'd take a stab at this. Pro Tools only supports their own proprietary plugin formats and does not support VST plugins directly. However, on the web you can find numerous examples of third-party applications that provide some form of wrapping and expose VST plugins with a different plugin format. We have not tested any of those directly, however I realized that Avid lists a particular VST-to-RTAS converter (linking to as supported for Pro Tools 10, so I guessed that could be the one you tried.
On the reference page for VST TO RTAS ADAPTER V2, I noticed that officially it only supports VST 2.3, and I know Audio System Toolbox generates plugins in VST 2.4 format. I wonder whether that could be the source of the issue.
Other thoughts:
  • Ensure you generate a 32-bit plugin by using the -win32 flag with generateAudioPlugin
  • The VST plugins generated by Audio System Toolbox do not come with a custom UI and instead they rely on the default UI rendered by the host environment. I am not sure whether this format conversion workflow still allows default UI rendering, so that would be something else to check
I hope this helps.

Thanks a lot Gabriele. Yes, I´m using FXpansion as VST_RTAS converter engine of plugins generated in 32b. I haven´t realized about VST format version difference and really seems to be the root cause of the issue, as stated by FXpansion in the following link:
May be in the future, the code they´re able to offer to manufacters developers can be incorporated :-)
