Updated SDK from version 33 to 34.
Description
Find the key of your song on the left side, and then drag the right side of the screen until the key of which you wish to transpose is next to the original key. Now, any key/note change in the original key will have the transposed key/note seen directly to the right of it. Clear as mud, right?
(You can drag either side up or down)
