I'm assuming we're getting the full orcehstration. Oh, and those Vortual Orchestra things really scare me... the concept anyway!
I just checked over at MTI's site... 18 pieces, three of which are Keyboard Books. Looks like they just cut down on the strings. However, the percussion books look like the originals:
Percussion 1: Gamelan, Tympani, Large Tam-Tam, Crotales, Glockenspiel, Vibraphone, Xylophone, Ching, Large Odaiko, Bell Plate, Tsusumi, Hindu Bells, Kin, Tibetan Skull Drum, Marimba, Mokugyo, Tambourine, Suspended Cymbal, Coin Clapper, Thai Bell Tree, Odaiko, Tubaphone
Percussion 2: Thai Bell Tree, Large Odaiko, Gran Cassa, Kyeezee, Drum Kit, Toms, Chinese Cymbal, Small Sustaining Cymbal, Piccolo Wood Block, Xylophone, Tsusumi, Hi-Hat, Mark Tree, Sistrum, Suspended Cymbal, Kin, Marimba, Tam-Tam, Chest Rattle, Gongs, Small Wood Blocks
That's a LOT of doubles! -And if I remember correctly, when the show was running in NYC, the percussion players were some of the highest paid pit players due to the number of doubles they each had. -It was also "infamous" for being an amazingly physical book, but it was also fascinating to watch each player in their respective "cages".
