Hi there guys. I need a program for a friend (guitar player) that will slow down the tempo/speed of a tipical song. The key that the song is played at should remain the same during the slow down process, so he will be able to listen, understand and eventually reproduce the song.
I already have a program that successfully does this job - "Amazing Slow Downer" (see links) but he is not entirely satisfied with this one. Do you guys know any other software out there that will do this for him?
Thanks for any help.
