Note: You cannot tune the keyboard while a prerecorded tune is displayed or playing.

Follow these steps to tune the keyboard.

1.Repeatedly press TRANSPOSE/ TUNE/MIDI until the display shows Tune and the current pitch setting.

Note: The number on the display is the number of “cents” to which the keyboard is currently tuned, com- pared to its default pitch. A cent is the measurement that represents the acoustical interval between two tones. 1200 cents equal 1 octave. You can tune the keyboard to within 50 cents (101 levels) of its default pitch.

2.Within 5 seconds, repeatedly press

or + to lower or raise the key- board’s pitch. Each time you press the key, the number on the display decreases or increases by 1 (cent).

Notes:

You can use the number keypad to raise the pitch by entering the cent change value.

The keyboard automatically resets the tuning pitch to the default value of 00 (cents) each time you turn off the keyboard or play the pre- recorded tunes.

USING TOUCH RESPONSE

The MD-1150 has a touch response fea- ture that lets you adjust the volume of your music’s tone based on how hard

you strike the key(s), so you can add emotion to your music.

TOUCH

RESPONSE

To turn on touch response again, press TOUCH RESPONSE so its indicator ap- pears.

Notes:

The touch response setting does not affect auto accompaniment or received MIDI data.

The MIDI data sent out from the MD-1150 is affected by the touch response setting.

USING A SUSTAIN PEDAL

For added flexibility and control as you make music, you can connect an option- al sustain pedal (not supplied), available through your local RadioShack store. A sustain pedal lets you sustain the key- board’s sound.

To connect a sustain pedal to your MD- 1150, insert the plug on the pedal’s cord into the SUSTAIN jack on the back of the keyboard.
