I recently wrote a book entitled "All about Hauptwerk". It is aimed at those people who are contemplating, or actually developing, a Hauptwerk virtual pipe organ.
The book has been very well received, and so I would like to bring it to the attention of those who use this forum.
The book is here: http://lulu.com/kaspencer (http://lulu.com/kaspencer), and the video about the book, designed to let you know what you get when you buy the book, is here: https://www.youtube.com/watch?v=0IRvB5oV6Pg (https://www.youtube.com/watch?v=0IRvB5oV6Pg).
Many thanks,
