I know this was all months ago, but I recently made another video on using Helix Native (AU) with Gig Performer 5 to synchronize LED status (preset and snapshots) with a foot controller. It may be of some interest to Helix Native/Gig Performer 5 users. It’s all work in progress but it’s getting there. The snapshot part is based on the script by @rank13 from this post but adds LED feedback: Helix Native Snapshots script for VST3 converted to AU
