M-Audio Radium 49
Radium49 gives you the same control, flexibility and power as the Radium61, just with an octave fewer keys to accommodate tight spaces and even greater mobility. You get the same quality keyboard, 16 MIDI-assignable controllers and built-in MIDI interface-and we're only talking 6 pounds. You can even power Radium49 from the USB bus or batteries so that you can play, compose, record and mix with ultimate mobility.
