I have this issue since my template is almost done. When i undo things or delete tracks with VEP on Logic Pro, it triggers a kind of reaload in the instances or something like this slowing a lot the process of simple things. I use one instance for each instrument, with ca 5 subinstances of many midi channels, everything decoupled and preserved.
WHen i teach on Zoom, Zoom sets a new audio device and this does again trigger a whole loading proccess in the instances, making everything really bad to work with
I could test the coupling function, but this would dramatically change my workflow and ... it is not right
