This is more about our love of synths and music production than anything else. We provide production guides and e-notebooks for the price of a cup of coffee and to maintain the upkeep and continuance of this project. Our books are guides, they are reference books and they are notebooks delivered in a PDF ebook format to enable your own notes and annotations to be added when used in apps such as Goodnotes, Adobe Acrobat and other document readers and to be compatible with tablets, PCs and mobile phones. This site also incorporate the OP-1 Microsite, formerly the GO-P1 resource site. We welcome feedback and comments. Thank you for your continued and valuable support.
