So , if I understand this correctly; Use BIAB to create the basic song or backing track. Then "somehow" open it in RealBand to do things like edit a midi drum pattern with the Piano Roll, lengthen the notes of the midi Strings track, copy/paste/replace RealTracks sections, record my voice and instrument on audio tracks along side the BIAB generate and RB edited tracks. Add VST and DXi effects, render the song to .wav or .mp3, etc...
Is that the basic idea?


Does the noise in your head bother me ?
