Actually there are six instruments played into the BR soundtrack:
CS80 ( Brass , strings, leads, efx )
VP330 ( strings, choir )
GS-1 (mallet, FM el.piano )
Prophet 10 ( sequenced bass )
Emulator ( sampled percussions )
Fender Rhodes MkII
PS: I would badly like a VP330 emulation which , apart from the chorus shouldn't be too difficult to emulate but, sadly , I should kill all the managers at Roland before Arturia could obtains the rights on the brand and names.....
BTW, arturia, why not name it otherwise?
