I am interested in a software package called Transcribe (
www.seventhstring.com/).

It is supposed to slow down music, isolate different instruments, and generally make it easier to transcribe or learn a piece by ear. Does anyone have experience with this software or any similar software? Is it useful or is it junk?

Does using this such software provide a smoother transition to developing you ear and evntually being able to figure out the part at full speed, or is it just something that makes you full good, yet keeps you from the goal of hearing a piece of music ( bass line) at full speed and being able to play it?
Thanks,
