"Old school" classical musician, studied piano, cello, conducting, composition (etc., etc., etc.) at Guildhall, UK, in the 1960's. Heaps of experience with classical orchestral and chamber playing, a fair bit of composing, and a lot of arranging - I think like a player, not like a publisher. I've used Sibelius Software almost from its inception, from version 1.4. I am not a professional muso, but worked in the audio industry - radio and TV - until my retirement. I ain't a computer whiz-kid (I'm 67!) but I'm a damn good musician.
