I am not able to increase the BPM by 10%, that is, from 110 to 121. With MIDI tracks this is no problem at all. The problem is with the WAV tracks. Follow my thought. 1) If I increased the BPM by 10% when using the STRETCH tool (CTRL+Shift+Mouse) I drag the track size to 90%. 2) Or, if I increased the speed by 10% the same decrease should be done on the WAV track. Even doing it this way, the sync is not established. I'm not here worrying about the PITCH of the voice or
