MOTM

Add me to the list of one who would pay $100+ for such a book.
But, not just any book.  I'd like to see patching diagrams.  But I'd 
also like to have detailed explanations as to what each module is 
contributing to the sound and what the thought process was in deciding 
to do the patch the way it was done.  And I'd like to see it cover a 
large range of instruments.

For those looking for other sources, there was a long series of 
articles that ran in Sound on Sound magazine on this topic.  I think 
most of them can be accessed online.  I think the column may have been 
entitled Synthesizer Secrets or something of the sort.
