Khpro Changes Pitch To Audio Tracks

[Emilio Guifarro]

I have a music editor and after editing an audio track to convert to karaoke i noticed that KHPRO opened it but, with a lower pitch (was so slow, about two notes below the normal pitch that was distorted). I opened the editor again to compare, also with WMP and make sure was not my ears deceiving me; both played the song in the right pitch, it was KHPRO.
¿DOES ANYBODY KNOW SOMETHING ABOUT IT TO HELP ME?

Thank you
