UPDATE: I have revised the bigger AU3 template I did. I have discovered a bug in LogicPro that negatively impacts these tempaltes that were created with Logic 10.4.4. The problem is related to the way instrument channels are handled in Logic 10.4.5+. This problem also negatively impacts the AU3 templates provided by VSL, FWIW. The click channel is lost in the environment.
The good news is that its very easy to manually build up a new AU3 project template under 10.4.5+ by using the instructions found here:https://www.logicprohelp.com/forum/viewtopic.php?f=9&t=143416
