If you regularly transcribe texts or conversations, you are accustomed to the problem of changed passages not fitting into their space anymore.
Tedious adjustments are often neccessary.
By using a score, the conductor can overview the simultaneous play of multiple instruments, without loosing track of the interlinear structure of events. In conversation transcription, roles would correspond to speakers. Tracks are also used for comments, translations, and other things. As in music, when transcribing it's important not to miss your entry. The speakers' names or arbitrary transcription headers of your liking can be entered into the name fields.
