I have learnt a great deal from the sections posted online so far despite having used many of the 'tools' on and off for years now - we never stop learning and it is always useful to go back over the basics - review what you think you know.
For me the mixing section was the most useful of all right up to the point when it was announced that Alan & Co had decided to finish mixing the project at home. That didn't help me at all!
Also, on watching these sections for a second time it looks as though a lot of work had already been done on the DAW prior to the mixing we got to see. I am hoping that the versions released on DVD may have more depth. Perhaps that's why it is taking so long to complete things?
