This is an all GPO render from Noteworthy Composer via GPO Studio. There are 48 different instrument patches in the final mix, but I did that by rendering the score twice with two different orchestra setups in GPO Studio, with 24 instruments per pass. This gave me two dry wave files which were essentially two different orchestras playing the same score in synch with each other. I mixed these together in Reaper and added impulse "ReaVerb" from St. Nicolaes Church.
Total work time from printed score to final render, 34 hours.
Here's the link to the MP3. It's 7 minutes 12 seconds, and 13.2 MB.
For general guidance I used a Deutsche Grammophon recording (Berliner Philharminker, Chor der Deutschen Oper Berlin, Herbert von Karajan conducting).
There are still some flaws, among them they annoying machine gun effect in the last few measures. I'm working on that, but I'm not quite sure how to fix it.
