Note that this setting is independent from the ProTools hardware buffer size, which you will generally want to change to the same matched value simultaneously.

This user editable field allows you to select the Buffer size you wish to adapt and convert the plugs. Also in the application is a small window titled 'Block size for buffered Plug-ins'. There are also 3 optional radio buttons for advanced use. It consists of two buttons, one to scan and detect your VST plug-ins and the other to delete the converted or adapted plugs.

The configuration utility is very easy to use. The FXpansion adapter consists of a configuration application that will detect your UAD-1 plug-ins, convert them automatically, and put them into the proper Digidesign plug-in folder for use in Pro Tools. While 'adapted' UAD-1 plug-ins did work in initial tests on a TDM system, Universal Audio recommends the use of our TDM plug-ins for Pro Tools TDM systems. NOTE: In this release, only Pro Tools LE is supported on Mac and Windows. Now users of Pro Tools can take advantage of the great sounding UAD-1 inside of Pro Tools. The VST-RTAS adapter converts the UAD-1 plug-ins for Windows and for OSX into RTAS compatible versions to be used in Pro Tools and Pro Tools LE. If in addition to using a UAD-1 card with your Pro Tools LE system, you wish to use other VST plug-ins, you must purchase the full version of the FXpansion Adapter, which is available from FXpansion. This special version of the VST-RTAS adapter is designed specifically to work with the UAD-1 it will not work with other VST plug-ins.

Original Mackie card owners can purchase the full version of the adapter directly from This special version of the FXpansion Adapter welcomes users of Pro Tools(r) LE software on Mac OS 10.2 and later and on Windows XP to the UAD-1 family.

This adapter will be a free download for all Studio Pak and Project Pak owners via the my. website. Universal audio is proud to announce RTAS support for the UAD-1 via FXpansion's third party VST-RTAS Adapter. Support Report: Randy and Jor answer your UAD-1 Questions
