That's all very technical.. :) lol.. After reading a majority of the posts contents, I still don't think I could easily construct a string section to add ambience to a backing track.. :)

Something that I have misunderstood 3 times today now is this V7 thing.. I was thinking it's the fifth chord from the root played in the dominant 7 mode or whatever.. But from your explanation after that, it doesn't sound right at all now..

Well D7 is D dominant 7.. which would be the 2nd chord from the root.. (a whole step/tone).. not the fifth like I thought.. So if you're moving from D7 to G.. that's II7/V isn't it?..
