Some of you might want to check out Melodyne also (http://www.macupdate.com/info.php/id/10319).

Version 1.15

Melodyne Cre8, which is what your link is for, costs $369(ouch!!!), whereas Midi VST costs $59......big, big difference in prices!
Melodyne might very well be more sophisticated, I don't know, but many of us just can't justify or afford spending $369 but can readily handle $59.

"It is also the very first Audio-to-MIDI software available for MAC OS X."

I can't review this product, as I've never used it, but the above statement in demonstrably false!

Myriad Software's Harmony has had this capacity for years. It's results are not all that great, but this developer should not be making false claims.

Thank you for your comment.

You are right, we should better use "first known" or "first popular" instead of just "first", but currently we are completely unaware of any other audio-to-midi software for MAC OS (X).

As far as I can see, current version of Harmony Assistant by Myriad software does not claim to have audio-to-midi functions.



Harmony Assistant comes with a script called "digital to note" which attempts to convert a (mono) digital track to midi notes. I have used it several times, but it does not do a terrific job, especially if your playing is slightly off-key. Nevertheless, it does indeed have this function.
