I have been using Sonarworks and just love it!!! MIXING on headphones or speakers has become much less tiring because I now know they are both completely FLAT. Less searching around and popping back and forth to listen to my Mixes on different devices. They now sound better than ever on all devices when using Sonarworks. Just remember to ALWAYS disable Sonarworks when you mix down. Otherwise you will have a really weird sounding mix. Just a detail which Sonarworks also mentions in their guideline! Conclusion: buy it , use it - you'll be amazed. Songwriter Till
