I'm currently doing something similar and wanted to give 3 pieces of advice to anyone wanting to do similar: 1. Don't buy a 2 or 3 octave keyboard like I did.

I'm currently doing something similar and wanted to give 3 pieces of advice to anyone wanting to do similar: 1. Don't buy a 2 or 3 octave keyboard like I did. 2. Synthesia is great. Guitar hero for a midi keyboard. 3. musictheory.net is a great interactive way to learn some basics. My learning is mainly geared towards producing for games, so I thought I could get away with a 25 key keyboard, but I regret it a lot.
