Thanks for your replies.
I stilll havenĀ“t made a final decision about wich Strings-library I will buy. Horizon "Chamber Strings" or "Strings" Pro edtiton? I really have this obsession for large string ensembles [:D]
Anyway: How about another solution for making strings sound big ?
Lets say I type in a piece for strings in a sequencing program using "Chamber Strings"-samples. Then I add articulations,releases by perfromance tool,dynamics,strokes,bows etc. until I get the audible result I want,but dry, without any reverb. After that, I save the whole piece (all the strings instruments) as a audiotrack on the sequencer program. Then I copy that audiotrack so that I have two identical audiotracks starting at the same point. So, what if I then change the second (copied) audiotrack by altering the pitch and starting point by extremely small amounts. Then add a suitable reverb and mixing.
As I see it, the result may be that the final audible result would sound like a larger ensemble because og the slight differences in intonation and rythmic precicion between the first and second audiotrack. I may be terrible wrong about this, but I do wonder if this is possible to accomplish. I donĀ“t have my DAW ready yet, so I canĀ“t try this out myself yet.
