...the instruments are individually distributed to the five channels. For example: violin left, viola right, flute center, cello left surround, piano right surround.
Eldartford - This is the approach to multichannel music that I find unnatural, since I am not accustomed to hearing music from the middle of a chamber group. Having said that, I don't want to imply that other people should feel the way I do. It's a matter of preference, and in this case, I don't believe that one preference is more valid than the other.
The effect is to put the musicians in your room as opposed to the usual approach of transporting you to some recording venue.
I think you are right about this. So, whether you find this approach to multichannel music appealing depends largely on whether you prefer the illusion that "you are there" or the illusion that "they are here." That distinction was discussed at length in another thread.
