The keyboard is semi-portable at 8.8 pounds and supports battery power, although you’ll lose Alexa support when you aren’t plugged in. Roland offers a Piano Partner 2 app for Android and iOS to help you master the instrument on your own terms. This isn’t a trivial purchase by any means, but it might be worthwhile if you like practicing with recorded music, hate cryptic menus, or just want to ask about the weather without leaving your seat.
