Hello Mark and list!

A few months ago I made an approach to an automatic pitch correction patch,
like the autotune. I'm just a newbie, so I'm afraid the code is a bit
messy... nevertheless it works!

In the attached patch you can select the 'scale' of notes, as you said, and
set a coefficient for the level of correction. A coefficient of 100 makes
the 'cher effect', and with 50 - 60 you get a natural voice.

If you introduce any improvement, please let me know!

By the way, related to pitch detection and correction, i'm very impressed
with this:

It's a polyphonic pitch detection and correction software... wow! Does
anyone in the list know something about the secret behind this kind of
magic??? ;-)
