I'm trying to edit an orchestral piece and continue it when I do. As often happens, when I do edit, in this case the 2nd violins go silent even when I haven't pressed the mute button and, though I've tried everything, I can't find what may have gone wrong. I could go back to an earlier version I guess but this happens so often that I'd like to deal with it this time. (Yes, I've checked the vsl keyswitches!) I can also check on the vsl forum if necessary. Ed Gold PS: I'm pretty sure the problem is in Logic and not VSL. What I had apparently done to mute this track or others on other occasions (sometimes multiple tracks) is to delete-paste (command X to V) notes from one track into another. In most cases the muted tracks seem unrelated to the tracks I'm operating on. VSL has its own problems mostly related to large file sizes and extremely slow loading.
