Connections

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 )
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 )
Connect the keyboard to an audio equipment using a commercially available connecting cord with a mini plug on one end and two PIN plugs on the other end. Note that the mini 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 )
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 mini 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 connecting 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.

[Connection Example]

NOTE
You can also connect the keyboard's MIDI terminal to a computer or sequencer. See "Using MIDI" for details.

Using Song Bank Tunes for Practice (3-Step Lesson)

3-Step Lesson makes it easy to master Song Bank tunes. You can learn to play melodies by viewing the guide indicators that appear on the display. In Step 1 you learn to master the timing of the notes, in Step 2 you play at your own pace, and finally in Step 3 you play along at normal speed.

Step 1: In this step, you master the timing of the notes. Pressing any keyboard key plays the correct melody note, along with accompaniment.

Step 2: In this step, you learn correct keyboard keys you need to press. The on-screen graphic keyboard and staff display show the notes and the keys you need to press to play them. You can play at your own pace, even if it is very slow. Both the on-screen indicators and the accompaniment wait until you play the correct note.

Step 3: In this step, you play along at regular speed. The on-screen guide indicators and accompaniment change at normal speed, without waiting for you to play the correct note.

Using Step 1

1. Press the SONG BANK button, and then use the 3-STEP LESSON button to cycle through the 3-Step Lesson steps until the Step 1 indicator appears on the display.
   
2. Find the Song Bank tune you want in the "Song Bank list" and then enter its two-digit tune number.
3. Press the START/STOP button.
   • This starts playback of the Song Bank tune. When playback reached the point where the first melody note should be played, the key you should press is indicated on the on-screen keyboard, and the note you should play is indicated on the on-screen staff. At this time, play back pauses and accompaniment stands by, waiting for you to play the first note. Press the indicated key to start your practice session.
   • Playback of the tune resumes as soon as you press the indicated keyboard key. When playback reaches the next melody note, accompaniment pauses again, and the on-screen keyboard and staff indicate the note you should play. Even if you make a mistake and press the wrong key, the keyboard plays the correct note.
4. To stop your practice session, press the START/STOP or the 3-STEP LESSON button.
   • Pressing the 3-STEP LESSON button to stop the practice session also selects the next step (Step 2 in this example). At this point you could start a Step 2 practice session, if you want.
5. To turn off 3-Step Lesson, press the 3-STEP LESSON button to cycle through the steps until there is no indicator in the 3-Step Lesson indicator area.

Using Steps 2 and 3
In step 1 of the above procedure, use the 3-STEP LESSON button cycle through the steps until the Step 2 or Step 3 indicator is displayed.

• In Step 2, you learn correct keyboard keys you need to press. The on-screen music staff and graphic keyboard show you the notes to play and the keys to press. You can play at your own pace, even if it is very slow. Both the onscreen indicators and the accompaniment wait until you play the correct note. Unlike Step 1, accompaniment does not restart unless you press the correct keyboard key. Playback resumes when you press the correct key, and continues up the next melody note, where accompaniment pauses again, and the onscreen keyboard and staff indicate the note you should play.
• In Step 3, you play along at regular speed. The on-screen guide indicators and accompaniment change at normal speed, without waiting for you to play the correct note.
