I'm enjoying your music posts, and like how you've just jumped in & started posting stuff online right away. I write music myself, but have held back from sharing it - I need to get over that.
I have the Dance Music Manual & it's a great book. If you're interested in learning more theory (which I recommend - it gives you so much more flexibility), you might like 'Music Theory For Computer Musicians' by Michael Hewitt. The two sequels on composition and harmony are also worth checking out.
