i too had a problem with the key changer,when i used to do karaoke (i kinda stop doing it for now) but like other people said, i seldom used it, what i usually do was if the singer wanted a lower key version of a song, i usually select on an SAV brand( SAV seems to have a low key version of any song)..and i had a singer that will tell me to either +/- key..since she's been singing the same songs all the time...
