The CTK4400 from Casio is a portable keyboard with 61 full-size dynamic touch keys, Step Up Lessons for beginning keyboardists, onboard stereo speakers, and more. It features 600 tones, and a fully featured auto accompaniment section includes 180 rhythm patterns and 152 songs. A stereo mini audio input makes it possible to connect an outside sound source like an iPad, MP3 player, or smartphone. The music will play through the keyboard’s speakers, and you can play along on the keyboard. You can even sample sounds and trigger the samples.

For beginning keyboardists, the CTK-4400 offers extensive learning features. Its Step Up learning system includes a Voice Fingering Guide, a Note Guide, and Performance Evaluation. It teaches songs phrase by phrase, and keeps track of your progress. The built-in songs provide additional practice material, and you can turn off one of the “hands” as the song plays, so you can play its part. Thirty-two registration memories allow you to store settings such as tempo, tones or rhythms easily. For added creativity, the keyboard has an arpeggiator and recorder.

At the touch of a button, concert hall reverb can be applied to the sounds, adding authenticity when you play. The keyboard comes with a detachable music stand and is powered by an AC adapter. Alternatively, it can run on six AA alkaline batteries (not included) which typically provide about three hours of continuous operation.
