Thank you for articulating my EXACT questions!I am not the expert, but this flies in the face of everything that I have heard.
First, what is a "suite DAW session". In fact, what are suites?
And the music editor placing the suites to picture before the real writing starts - that makes no sense.
My understanding is this:
There is a spotting session, where the director and the composer (and others) watch and talk about the film and the music to be.
Then, the composer goes to his studio with temp music, which was put together by the director and picture editor, and sometimes the music editor.
And that is when the real writing starts; the composer writes the music to the film, all the while the assistant will flesh out the ideas and partial cues in a DAW so that the director can hear complete cues. Feedback is given, and changes are made by the composer at the director's request.
And so on.
