I wrote this topic so long ago I had virtually forgotten it existed. It is one of the old, old topics I migrated from the old forum to the new. This dates back at least ten years I would think.
I will certainly have to re-read it and check whether the quality of writing, information and graphics is up to par. I may also check if it would benefit from an update - either in presentation or in the perspective used to view the major / minor mixing.
