Pitch Changer
An option to change the pitch of a track/song. I have checked "time-stretch" option, so I can speed up/down without changing the pitch. But sometimes, playing backing tracks to learn some songs and play-along, there's ONE BIG problem: the tuning.
So it would be awesome to have an option to change the pitch, so I can tune the song to my instrument's tuning.
An important thing: music notes "have" 440Hz, which are semitones, 1/2 of a tone. So when changing the pitch, we should be able to know how many semitones are we changing up/down. I don't know if I've explained it well :/
