I'm looking for recommendations for a keyboard to use in the real world, as well as in Rock Band 3. Both my wife and I are former piano players who would like to start playing again. We also live in a small home and have plans to move in a couple of years, so a full-tilt piano is not in the cards right now. We would, however, like to get a solid keyboard that we could play in the real world, but also plug in to Rock Band 3. I have snooped around but haven't come across something that meets our requirements of a good keyboard, USB connectivity, and MIDI connectivity, so I was wondering if there were any suggestions out there? All brands and price points considered; just really wanting to know what's out there!
