The RockJam RJ640 is a 61-key portable keyboard aimed at beginners and casual players. It runs on wall power or six AA batteries, has built-in speakers, a headphone jack for quiet practice, a mic input, aux in and USB-B and MIDI outputs. Its 350 tones and 350 rhythms plus 50 demo songs and a 46-note recorder give more variety than most starter keyboards, though it has no touch-sensitive keys, no pitch bend or modulation wheel, and no drum pads. Owners rate it well as a first keyboard and for practice; serious players will want weighted or velocity-sensitive keys.
