What he said I find it useful but I'm far from competent.I use Finale Print Music (2009), but I'm far from a competent user as I don't use it that often, but when I have it's been good. Was there anything in particular you were interested to know about it?
My only slight bugbear with the company is that they seem to have decided that each year there should be a new version, when I realised that my 2009 version had been superseded by the 2010 version I had to look hard to see what had been upgraded! Needless to say I didn't upgrade.
I tried the free demo of Sibelius, but wasn't taken with it and then found out the price, ouch! I believe it's all wrapped up into Avid now, they do ProTools etc.
