Hi.
The tempo changes within a single piece, such as Andante, Allegro, and Andante.
I would like to change the scroll speed accordingly. If there is a way to do this, please let me know.

Currently, I use buttons to start and stop scrolling, but it would be convenient to have a start button that specifies the scroll speed.

If there is a good way to do this, please let me know.

There isn't currently a convenient way to have multiple different scroll speeds within a single song/piece. About the closest thing you can do is tie the scroll speed to the metronome tempo and then switch between the metronome tempos using a touch action.
