Open your own audio files, repeat the part you need, and use Pro to adjust speed and pitch independently. [A-B Loop & Saved Points] Set a start point (A) and end point (B) to repeat a section. Your loop points are saved per file and restored when you open it again. [Speed Control] Slow down a passage without changing its pitch, or speed it up as you improve.
