Pitch Change on Original Songs
The software allows to transpose the chords to a different key. However the music playing in the background is in the original Key and not the Transposed key.
Changing the playback pitch is unfortunately impossible (we stream from YouTube, for example, so we can only do what their API allows us to). Furthermore, we would not be able to make changes to videos without the artist’s content. Sorry that this is not a feature we will be able to implement.
