So I am working on a bootleg (unofficial remix) of a song and I have had to speed the track up to 74% of its original speed as I produce drum and bass. This sounds fine during playback however if I export it or bounce it to a master track the vocals of the song stay normal as they should however a piano that is in the back ground goes out of pitch and pitch shifts both up and down almost as if it is being manipulated by a sinewave. I have tried just about everything I can think of so all suggestions are welcome.
Thanks in advance everyone!
