Frequently Asked Questions - CTK-720 CASIO

How to connect the CASIO CTK-720 keyboard to a computer?

Use a standard USB cable (type A to type B) to connect the keyboard's USB port to your computer. You must first install the USB MIDI driver provided on the included CD-ROM. Once installed, the keyboard is recognized as a MIDI device and can exchange data with MIDI software.

How to use auto accompaniment?

Select a rhythm with the RHYTHM button and the numeric keys. Set the POWER/MODE switch to CASIO CHORD or FINGERED. Press START/STOP to start the rhythm, then play chords on the left part of the keyboard to trigger automatic accompaniment (bass and chords).

How to change the keyboard sound (timbre)?

Press the TONE button, then enter the three-digit number of the desired sound using the numeric keys. The number is found in the tone list in the appendix of the manual. You can also use the [+] and [-] keys to scroll through sounds.

How does the 3-Step lesson function work?

Learning takes place in three steps: Step 1: master the rhythm by pressing any key. Step 2: play the correct notes indicated by the keyboard guide. Step 3: play at normal speed. The Scoring mode assigns a score out of 100 after step 3. Use the STEP 1, STEP 2, STEP 3 and SCORING buttons.

Can I connect a microphone to the CTK-720?

Yes, the keyboard has a MIC IN jack on the back. Connect a standard dynamic microphone (jack) and adjust the microphone volume with the MIC VOLUME slider. Use the microphone's ON/OFF switch to activate it.

What is the battery life?

With new alkaline batteries, battery life is approximately 4 hours at medium volume. With manganese batteries, it is approximately 2 hours. Rechargeable batteries are not recommended.

How to transpose the keyboard?

Press SETTING several times until the transpose screen appears (e.g., '00 Trans.'). Use [+] and [-] to raise or lower the pitch by semitones (from -12 to +12). Transposition also affects the auto accompaniment.

How to set the keyboard tuning?

Press SETTING until the tuning screen appears (e.g., '00 Tune'). Use [+] and [-] to adjust the pitch in 1-cent steps (range -50 to +50 cents). 100 cents = 1 semitone. To return to the default setting, press [+] and [-] simultaneously.

How to clean the keyboard?

Unplug the AC adapter before cleaning. Use a soft cloth lightly dampened with a solution of water and mild detergent. Wring the cloth well so it is almost dry. Never use thinner, benzene, or harsh chemicals.

How to use a sustain pedal?

Connect an optional sustain pedal (CASIO SP-3 or SP-20) to the SUSTAIN jack on the back of the keyboard. For piano sounds, the pedal sustains the notes. For organ sounds, it holds the sound until you release the pedal.

Phones/Output Terminal

Before connecting phones or other external equipment, be sure to first turn down the volume settings of the keyboard and the connected equipment. You can then adjust volume to the desired level after connections are complete.

[Rear Panel]

Connecting Phones (Figure 1)

Connecting phones cuts off output from the keyboard's built-in speakers, so you can play even late at night without disturbing anyone.

Audio Equipment (Figure ②)

Connect the keyboard to a audio equipment using a commercially available connecting cord with a standard plug on one end and two PIN plugs on the other end. Note that the standard plug you connect to the keyboard must be a stereo plug, otherwise you will be able to output only one of stereo channels. In this configuration, you normally set the input selector of the audio equipment to the terminal (usually marked AUX IN or something similar) where the cord from the keyboard is connected. See the user documentation that comes with your audio equipment for full details.

Musical Instrument Amplifier (Figure ③)

Use a commercially available connecting cord* to connect the keyboard to a musical instrument amplifier.

* Be sure to use a connecting cord that has a stereo standard plug on the end you connect to the keyboard, and a connector that provides dual channel (left and right) input to the amplifier to which you are connecting. The wrong type of connector at either end can cause one of the stereo channels to be lost.

When connected to a musical instrument amplifier, set the volume of the keyboard to a relatively low level and make output volume adjustments using the amplifier's controls.

Split Tones (Tone Numbers: 108 through 112)

Example: 108 BASS/PIANO

This tone splits the keyboard so one range is assigned a bass tone and another range is assigned a piano tone.

Percussion sounds

Example: 241 DRUM SET

This tone assigns various percussion sounds to the keyboard. See the “Percussion Instrument List” on page A-5 for full details.

Polyphony

The term polyphony refers to the maximum number of notes you can play at the same time. The keyboard has 32-note polyphony, which includes the notes you play as well as the rhythms and auto-accompaniment patterns that are played by the keyboard. This means that when a rhythm or auto-accompaniment pattern is being played by the keyboard, the number of notes (polyphony) available for keyboard play is reduced. Also note that some of the tones offer only 16-note polyphony.

NOTE

- When rhythm or auto accompaniment is playing, the number of sounds simultaneously played is reduced.

Using the Microphone Jack

Connecting a commercially available microphone to the MIC IN jack makes it possible to sing along with the keyboard's built-in tunes. When connecting a microphone, be sure to first adjust the MIC VOLUME to a relatively low setting, and then adjust to the level you want after connecting.

1 Set the MIC VOLUME slider setting so it is on the "MIN" side.
2 Turn on the microphone's ON/OFF switch.
3 Use the MIC VOLUME slider to adjust microphone volume to the level you want.

Stop playback, disconnect the USB cable from and then reconnect it to the keyboard's USB port, and then try playing back the tune again.If this does not correct the problem, exit the MIDI software you are using, and then disconnect the USB cable from and then reconnect it to the keyboard's USB port.

Because of this, there may be a very slight difference in tonal quality and volume between sample ranges.
