Random, but regular crash within patch generates essentially the same crash report, which I've included below. My suspicion is that it has to do with the Kontakt 4 plugin. But I cannot reproduce it from any action, only that it happens regularly, but randomly, whenever the patch goes on for any length of time.

I'd include the patch, but because it uses so many VST's and samples, it would not likely help. If I'm wrong in this assumption, let me know and I'll post it.

Thanks in advance -- this has now crashed at two concerts and though I'm making progress (I think), I'd like to make this bulletproof.
