@schamass came up with a pretty good way to handle tails. It involves a little scripting. But when you set the bypass on a VST, the “envelope follower” holds it until the gate detects no more signal and then closes it. I used it in my JAM RackSpace . It should work as well in global as local.
My reasoning for not going that route is I tend to tweak settings for each instrument for each song. I don’t think individual song settings will be retained with the VST in global. Wouldn’t I need to build a script for each song to adjust settings for each appropriately? I also may have different splits, up to 5 in some cases. Again, I would think I would have to script to set those splits in global for each song. I would be curious to see an example of your gig file to see how you handle things.
