IK Multimedia CSR

SuStudio, since upgrading to TR CS 4.5 I am able to run the reverbs directly as inserts and sends, and in 64-bit mode (I checked the activity monitor and there’s no sign of the bridge). The 64 bit reverbs have new names though prefixed by ‘T-Racks CS’ (see attached screenshot) and are listed alongside T-Racks CS in the effects list. Have you tried deleting the old CSR VST plugins then reinstalling 4.5?
