Professional Literature about "mechanics" of analog and digital synthesizers

[imrae]

Michael Hettrick (of Unfiltered Audio) wrote an interesting PhD thesis about modular synthesisers. It doesn't really go into implementation details, but serves as a great overview of the different building blocks using in modular systems and the purposes they might serve.

Can you send me the link pls?
I´m unable to find it

Google 'Michael Hettrick thesis'

That works for me. It's called "Modular Understanding". It is also provided as a kind of user guide with his Euro Reakt collection of Reaktor Blocks.
