make sure you are opening the .MGU files and not the .SGU files because the .SGU files do not contain melodies only the .MGU ones do this is a common mistake when people first wonder about the extensions used by BIAB another possibility is that your melodies play through a MIDI channel like a soft synth or hardware synth whereas your other tracks could be RealTracks we need more information to help do you see the piano keys moving when the song plays if so then maybe something is muted in the mixer or in the Melody / Soloist tracks of BIAB
