What's also amazing is how good the audio processing is and how incredibly sucky the user interface is--I'm using the over-the-top graphical interface that looks much like the chart I showed before. To a certain extent, this is just par for the course with tools, but in this case the sucky user interface deteriorates the audio quality, when you end up adjusting the pitch for a region and that region includes brief moments that it pitch-tracked wrong and then when it tries to adjust to your target pitch it thus adjusts those in a correlatedly-wrong way. Man. I dunno.
Also, there's a lot of stuff I couldn't fix. I let my pitch drop at the end of lines way too much; like, the nice chorus harmony at the end of The Sun is really limited by the fact that the top note of the rising phrases is only held for an instant before it drops away. But that's something I can probably correct in performance pretty easily.
I dunno. Worth $300? (I could probably write my own, but not an efficient money tradeoff. Although at least my GUI wouldn't suck. And would allow a graph window larger than 400x300 or whatever that plug-in uses.)
