I never really learned how to play an instrument, but after a bit of a warm up I can start to get some nice melodies happening on piano/keyboard. It's all self taught (which probably shows...

), as I couldn't stand the thought of taking lessons. I've always disliked lessons. I like the personal exploration approach.
One thing I would like to do is learn to read sheet music. That would be awesome.
I purchased FL Studio back when I had money, so I've learnt how to get some great, unique sounds to come out of that piece of software. My girlfriend thinks I should be putting vocals into the tracks I make, but I've never taken singing lessons. I don't even have an overly Aussie accent, which is a shame in a way - such a voice could be entertaining for non-Aussie listeners!
I'd love to learn guitar (I've learnt a little...) and sax, and maybe develop some vocal skills.
