I've been playing electronic keyboards for years but have blindly jumped into buying a Yamaha m08 synthesizer. I just want to be able to play it and listen while I take my time learning the features. What acessories will I need to plug it in, turn it on, and just play the basic voices for now? Do I need some sort of amp? Does it have internal speakers? I'm sorry, the manual is greek to me. Any help is greatly appreciated. Jinx
