I was getting a little frustrated trying to keep my copy of The Secrets of House Music Production book open as I worked through the various tutorials. So, I decided to seek out a solution and this is what I was able to come up with. This type of spiral binding can be done at just about any sheet music store or printer/copy shop like Kinkos for a small fee. I paid $3.50 for mine.
This is a great solution and I highly recommend it because not only does the book now stay open to the page I want but I can save space by flipping pages back to back and the best part is that it lays flat as I work through the exercises. Enjoy!
