By the way, William, yes I have had music played by live ensembles quite a lot, although not for a long time - and when I had strings it was a rare treat (plus I used to do a fair amount of orchestration and then heard other composers' music played live). These days I edit magazines and do smaller music jobs here and there, almost always MIDI plus occasional live overdubs. Ten years as a struggling composer when I got out of college (Berklee) - with intermittent but not consistent success - was enough, and I was happy to land the job as editor of Recording magazine in 1991. Being able to get up every day and work on something I loved doing, without having to beg anyone for work, was great.
The subtext is that I don't feel it's necessary to accuse me of being a wanker to make your point. That's the tack you take when someone is being arrogant, and I've already posted without hesitation that Guy is a more accomplished musician than I am - and I say that without putting myself down but rather putting him up.
Please search iTunes as I suggested and listen to the first several versions of the Air. If you don't hear what I'm talking about then it'll be my turn to suggest that you're the one who needs to go to school before voicing an opinion.
