I just read this book. At first I was very delighted to find something to read about mixing sampled orchestra. Especially with VSL, where it is not easy to get a nice sound.
In the end of reading I must say, I was a little bit confused again, since there are no diffrent aproaches mentioned, wether you use analogue reverbs and ER generators or Impuls reverb with seperate ER instances. In this setup you only use one instance of reverb tor the master? Without sends to vary the reverb amount from instrument to instrument exept for ER amount. Also, the best convolution reverb available (altiverb) was not even mentioned.
Further more: it has been said here many times, that the best sollution is a combination of IR an analogue reverbs. Nothing about that.
I found your book interesting to read, but a little short for this rather complex topic of mixing. It seems to miss important information on getting the best sound possible.
I hope the next book will cover more details on the most important and complex topic: Room acoustics and mixing.
