I have a music WAV with two chords in it, and the second chord needs to be four times the duration of the first. The original recording is close but not quite there. So I tried Change Tempo from the Effect menu. I shortened the first chord by 50% and lengthened the second one by about 20%. Now they both sound distorted. The online manual says distortion will occur if you make “extreme” tempo changes. I’m frustrated that only 20% apparently is extreme.
Can someone advise me as to a better way to do this so I don’t waste more time?
