Dave Smith Instruments SYNTHESIZERS

The new diagram has the highpass filter included. There is one error 
though: The output has an A/D converter, should be D/A.

The Sig. Flow Diagram has been updated. The Output A/D label now 
reads D/A. Also, there is more detail on the input stage with the 
peak detector and envelope follower added.
