Some older installations of Logic will be able to open REX and RX2 files without any additional steps. However, most 64 bit installations require the installation of the Propellerheads REX Shared Library.
You can download this library directly from the Propellerheads site here.
Installation is relatively simple, but there is an additional step required to enable Logic to use the RX2 files. Here's how:
- Download and extract the .zip file Install rex.zip and run the installer package Install_Rex_1_7_library.pkg
- Download and extract the .zip file SetRexFolderPermissions.zip launch the file SetRexFolderPermissions.command
- Terminal will open – enter your password to set Permissions for the Rex folder.
- Launch Logic and enjoy dragging and dropping your Rex files into the Arrange window.
