Calculating 40 human voices...
And Virtual Singer stands up to the punishment. OK, MA can't play back all 40 parts at once - interleaving 40 audio buffers is a bit much, I suppose, for my poor abused 1GHz machine, but it renders out just fine to MP3. Now for the fun of tweaking - but after I've slept some more.
Spem in alium nunquam habui praeter in te
et propitius eris
et omnia peccata hominum in tribulatione dimittis
Creator caeli et terrae
respice humilitatem nostram
(I have never hoped in any but you, God of Israel, who will anger and yet be again gracious, and who forgives all the sins of suffering man. Lord God, Creator of Heaven and Earth, look upon our lowliness) -- my translation
