The direction for the Mass Effect music from the beginning was to have an orchestral score with certain elements replaced by synths in order to create an interesting retro-futurism style that gave it a 'timeless' quality... thus working well in sci-fi and lasting us through the years.
If we'd made something modern sounding at the time when ME1 came out then it would either feel very dated now or we'd have to change the style to keep it 'modern'... thus losing a bit of identity and character with the franchise.
See, this is why there will never be dubstep in Mass Effect. You don't want to date your material.
Likewise, if we had a purely orchestral score it would lose its sense of character and identity, becoming too generic and pulling you out of the world and feel that we're trying to create.
And this is why there's no Hans Zimmer.
There is no intention of changing this style at all. We did push it a little more towards orchestral in certain areas of ME2 because it was a darker story with more thriller/horror inspired moments at times. But that has no reflection on where we're going with ME3. It is it's own story with a whole lot more ups and downs, interesting characters and locations but most of all with far more emotion and plot twists than we've ever had before.
Ah, so the slight change in music reflected the change in overall mood! By the way, the guy who thought to have a different theme for each character? Give him a pat on the back.
Also, uh, if you had to put a number on that emotional content ratio versus the other two games....
Now, sometimes we bend the music rules for effect on specific scenes where we want to focus more on the emotional angles (which orchestras tend to work slightly better for as they're more expressive and culturally more emotive) or the techy/stylistic angles (which synths are much better at portraying in the ME universe) or even intensity/action (which both angles can emphasize in different ways). So basically, we try to find the most suitable style or feel for each particular moment.
Makes sense. Don't want to use a hammer when you need a screwdriver...
Thanks everyone 
Thanks for commenting/giving me the opportunity to try to make myself sound smarter and more important than the common forum rabble yet again!
See, I reply to developers, guys! That makes me cool!
