The plugin does not seem to be listening to automation data unless the GUI is open. This is the AU version. I saw that the same issue seems to exist within Ableton.
Gatelab version 1.1.3
Logic version 10.8.1
Hi FredrikTiC,
Thanks for reaching out. This is a known issue which affects certain setups and it will be fixed with our upcoming V2 which is coming later this season. Thanks for your patience.
