Cool, but which thread exactly? I'm an active reader and if you're referring to a thread you started yourself earlier this year, I read it and even participated on it, but then, still, here I came :) as I never saw anyone questioning if you could have an external generating indexes with "double" as a work around, and I'm still not sure what I'm supposed to hear in that example (it just seems it's not working for me - I just hear nothing in either "good" or "bad" phasor~), so if you have a thread that's right on it, please share, my memory or searching skills did not get me anywhere.
cheers
