[pitch~] – 2 bugs
I finally had some time to find a more or less repeatable procedure to show some problems with [pitch~] which annoyed me recently.
Max5.0.7, OSX.5.7, intel
Start Max and create a new patcher;
instantiate a [pitch~], open its help file;
start the [dac~] in the help file, and check it works (with the phasor input for instance);
close the help file, and the unsaved patcher.
Create a new patcher, instantiate a [pitch~] again, open its help file and start the [dac~] there. Check it works… it doesn’t for me, there is no analyse performed.
Delete the [pitch~] instance in the unsaved patcher, Max will crash quite often after a couple of seconds (sorry, I couldn’t find a reproductible pattern):

I’m having trouble reproducing that, but I’ll look into it.
I’d like to redo the whole analyzer~ suite with a better fft~ at some point. This one is getting a little old.
Also, if pitch~ isn’t working, I find that toggling the dac tends to get things started.
