When I have the budget, which is most of the time, I do the rough on an arranger and the final project in the traditional way, with live instruments and 8 or more tracks.
That's what separates my films from others.
Works for me. I'll hunt around here in a week or so and post a rough on arranger...a refinement on arranger, after input from the client and then the final full blown production.
The final project bills out at $1,000.00 plus a finished minute.
