USB Port For many musicians, the computer has become a music-making center. Connect the CTK-3000 to a computer using a USB cable and exchange MIDI data between the two devices. Send play data from the keyboard to music software running on your computer, or send MIDI data from your computer to the keyboard for playback. Built-In Sampling You can use the CTK-3000 to sample a sound from a portable audio player or other device, and then play the sound with keyboard keys. For example, you could sample the bark of your dog and then use the sound in a melody, or grab passages from a CD. The sampling feature is a fun way to create new sounds. Note: Samples are not stored permanently. Turning off power will cause any sampled sound data on the keyboard to be deleted. Internal speakers and battery-powering option for full portability. 110 Built-In Songs With Step Up Lessons The CTK-3000 comes with a bank of songs for your learning and enjoyment, from classics like "Greensleeves" or "Auld Lang Syne" to holiday tunes like "Jingle Bells." To master a song, it is best to break it up into shorter parts (phrases), master the phrases, and then put everything together. The CTK-3000 features a "Step Up Lesson" feature that helps you to do just that. The built-in songs are pre-divided into phrases to help you master keyboard play. Step Up Lesson takes you through practice of the right hand part, left hand part, and both hand parts for each phrase of a song. Master all of the phrases and you master the song. Music Challenge Keyboard Game Music Challenge is a game that measures your reaction speed as you press keys in response to on-screen keyboard indicators and fingering guide indications. Auto Accompaniment Simply specify a chord and the keyboard automatically produces the matching rhythm, bass, and chord patters. One-touch fill-ins make accompaniments sound interesting and natural. 150 built in auto-accompaniment rhythm patterns. Transpose Function An easy operation instantly changes the key of the keyboard. Audio Input Play along with MP3 or CD players or other devices by plugging them into the stereo mini input jack. Battery or AC Power Power the CTK-3000 with six AA-sized batteries (approximately four hours of continuous operation with alkaline batteries) or purchase the AD-5 AC adapter separately to power from your electrical outlets.
