I think it is extrordinary! I am not familiar with Bartok\'s night music, so I can\'t judge how it compares. Having said that, I think your music stands on its own, it doesn\'t need a horror movie... And it is extremely realistic!
Sharmy, I wonder if the less realistic quality of the lower register, bass samples is due to the reverb setting I used. I am usually conservative with my application of reverb. While the concert hall setting I use here does justice to the higher strings, it may diminish the edge of the base pizzicato and base stopped samples (and perhaps the base staccato samples).
I did not use any individual fx inserts. I mixed down all the tracks through one global reverb setting.
