Further to my previous post: I have reinstalled the patch from a backup and all seems to be well again. What gets me, is how an EXS patch can just dump its reference to anything. Like I said before, I had only worked on this session last night, and sometime between then and now, the patch changed, and the pooter wasn't even on. Nuts!! _____________________________________________________ MATT MCKENZIE-SMITH MUSIC • AUDIO DESIGN • PRODUCTION PO Box 10395, Adelaide 5000, South Australia.
