Since somewhat 4 years I’m having problems opening files when I use some third-party plugins. It sometimes takes me 40 minutes to get Logic Pro opening a file when I use for example VMR by Slate Digital... I have to force Logic to stop and try again and again. Fabfilter-stuff passes smoothly, Plugin Alliance as well. Soundtoys can give the same problem, but Slate takes the cake... I’m on Logic ProX 10.4, Sierra, all the latest versions and drivers, iLok 3. Any suggestions?
