Not to hijack your thread but I find AT7 such a PITA on all fronts. On my machine, it takes a full SEVEN SECONDS to load each time I want to process a clip. I contacted Antares about this, and they told me that that was a *normal* amount of time, and to "keep in mind that Auto-Tune 7 is a powerful plug-in that requires a lot of processing power to run."
Ha! Yes that's a quote from them. I have never ever had any plugin take anywhere near that time to load. What a bunch of bull to reply with.
Also, I haven't had Autotune correctly sync the audio to the drawn wave form during auditioning the clip in graphic mode since version 3!!! And that's a showstopper for me. I often go into N5.5 to do pitch correction on vocals just so that I could use AT3 (which isn't compatible with N6).
