I think just getting a maschine would be a bit of a bad idea, mainly because sole MPC production is usually geared towards hip hop, which according to your tastes, isn't really in the cards, and secondly, all them piano chops would be going to waste. If I was you, I'd check out demo software of all the main DAW producers, choose which ever one you like the best, get a midi keyboard, and that would probably be the most natural way to write for you imo. Maschine is a good piece of kit though, and would definitely compliment the setup I mentioned, especially if you like to smack out your beats n shiz yo
