well, I have installed the Melos software...and my first impression is that it works better than I do....it allows you to whistle, sing, play, etc., into your microphone, and the notes you supposedly made appear on a staff on screen...then you can play it back or save it...but they DO say it takes practice..AMEN! I suspect that the sensitivity of your mic is important, along with all the settings for tempo, range...etc.

It says it will also take a mono .wav file as input, but I have not tried that yet...

I will try some other tests and post my opinion here...
