DMN has just posted a SmartSound Sonicfire Pro 4 review if you care to take a look. Sonicfire Pro 4 is software that allows you to create great sounding musical scores without having to hire John Williams. Only had time to skim the review but it looks like it is definitely an improvement since version 3. Here is what the reviewer had to say about the new Mood Mapping feature and Sonicfire Pro 4 in general:

I think its Mood Mapping feature is remarkable, and extends the usability and sophistication of this already-useful tool far beyond what it could do before. Best of all, Sonicfire lets you edit together music of the perfect length very quickly, or you can dig deep and make an intricately fine-tuned musical composition just for your needs. Highly recommended. 9.2 out of 10 stars.

Music is one of the most important pieces of almost any video production, and if you are pondering investing your money into music-creation software I would recommend reading the full review.
