The Configure application scans your computer for VST plug-ins, creates the 'wrapped' versions and places these in your Pro Tools Plug-ins folder.

VST plug-ins are converted prior to use with the Configuration Utility.Installation creates a folder containing the VstRtasConfigure utility and a local VST plug-ins folder. No extra background programs have to be running when you use the converted plug-ins - they just appear in Pro Tools alongside your existing effects. This 'wrapping' takes place off-line, using a configuration application, and once it's complete, FXpansion claim that the adaptor code uses next to no CPU power, so the plug-ins should be nearly as efficient as in a native VST host like Cubase. What FXpansion's adaptor does is 'wrap' the plug-ins in an extra layer of code that mediates between Pro Tools and the plug-in, making the plug-in appear to Pro Tools as if it was in the RTAS format. (They also have a VST To Audio Units Adapter, for OS X users of Logic who want to incorporate VST plug-ins.)

It seems quite hard to believe, but FXpansion's VST To RTAS Adapter can take VST effect and Instrument plug-ins and alter them so that they work as RTAS versions. The situation has been improved by Rewire support, as well as Native Instruments' adoption of RTAS, but there is still a great number of VST-format plug-ins (many free) that we've missed out on. While this supposedly keeps Pro Tools ' mixing environment within Digidesign's sphere of influence, it has limited the range of virtual effects and instruments available to Pro Tools users. VST plug-ins running in Pro Tools, thanks to FXpansion's adaptor.Īs the name suggests, FXpansion's utility allows VST effects and Instruments to be used in Pro Tools, but how well does it really work?īoth Pro Tools LE and TDM systems use Digidesign's proprietary RTAS (Real-Time Audiosuite) format for host-based plug-ins.
