the Pa4x will record both backing and vocal simultaneously no problem then save it .....
BUT,.....a Friend tried to do this on the Pa900 and it won't record the MP3 backing track?.....
when you push record then the song player to play the song nothing happens, ....
does the Pa900 have this function ability like the Pa4x or not?
or is it a different procedure on the Pa900 vs the Pa4x? confused1
Thanx for any help..
