}my game play just fine with the current file, but what I want is to make it slower and that mean I have to change the bpm from 128 to 240.
I have the current pos and len for the bpm 128.
I want to know if I can change the position of the notes based on the new bpm.
I do not want to change the audio file only the notes above so it can follow the new speed and still use the same audio file.
