Here is a text file of orchestral instrument ranges and transpositions, along with suggested stereo placement for classical orchestra. This is taken directly from Cakewalk's template information.

It'll need reformatting, because the .txt format loses the lovely tabs and such.

Also, I think that the octave numbers are strictly U.S. (and, by habitual extension, Canadian) useage. Middle C is C5 in this chart. Europe uses, I think, a positive/negative system with middle C as 0 -- I believe. Jaap? Is that correct?
