Now that Reason has been around for a few years, things are really starting to get interesting. As digital audio programs continue to become more cross-compatible with each other, new possibilities open up all the time.
There's a thriving international community of composers working with Reason on projects ranging from garage bands to Hollywood films. Here are just a few sites that I found helpful in my work on video games and during the writing of this book. By the time this book is in the stores, there will be many more.
