The score and parts have a typo error in the 5 part Allegro :: in the score the initial pick up bar is shown incorrectly as a whole bar rest, when it should only be a minim. This is then printed as such in the parts. This also affects the midi performance on the Mp3 where the mistake is noticable on the repeat, and also going on at Bar 25.
I think also typo in the Cello part of Largo bar 79 the C shown as a dotted crotchet, should be a dotted minim ?
Apart from that this is a really great piece of music, sounds great, but there may be other mistakes, so worth checking carefully.
