Query: Don't buy this

No support.Lousy manual.I cannot do with this product what I wanted to do because no one will answer my e-mail to help me. It is not user friendly.I made a mistake thinking this would work for me. I am a spinning instructor and purchased it to put together my spinning music. I wanted to use the fade in and fade out feature and cannot figure out how to do it. I have googled to see if there is any help out there and have not had any luck. I followed the limited instructions provided and it is a no go.
