In case anyone is interested, there's an offer for cheap guitar software which has music notation built into it over at
Software4Students UK Buy Guitar Software with Audio Editing & Audio Recording features
I recently tried out copies of Progression, Protégé and Notion 2.0 - along with Cubase which I got with a preamp in Rainbow (cheers Stef!).
I've also been using Audacity (which is a great free program) but figured I could do with picking up a few other apps.
Maybe Alex or someone could do an article on home recording software for the UGS site...?
