IMPORTANT OPERATION

Full Initialization

Use this procedure to return all keyboard settings to what they were when you purchased it. Note that this procedure clears all data from memory.

• While holding down the ENTER button, turn on keyboard power.

Res

• Press YES to initialize the keyboard or NO to turn on power without changing any settings.

Parameter Initialization

Use this procedure to return all keyboard settings to what they were when you purchased it. Note that this procedure does not affect user tones, user rhythms, registration memory contents, and display contrast settings.

• While keyboard power is on, press the [+], [–], and ENTER buttons at the same time.

Adjusting Display Contrast

• Display contrast can be adjust to one of 100 levels for easy viewing.

• Adjusting display contrast helps to make figures easier to read from any viewing angle.

• Within five seconds after pressing the CONTRAST button, press [+] to increase the contrast value (making the display darker) or [–] to decrease it (making the display lighter).

• After you release CONTRAST, the message “Contrast” remains on the display for a few moments, during which you can change the contrast setting further using [+] and [–] or by inputting a contrast value with the number keys. The contrast can be set to a value from 0 to 99. The initial default setting is 50.

et?

GM (General MIDI):

General MIDI standardizes MIDI data to play music with same nuance between different MIDI instruments. Among GM conformed MIDI instruments, or commercially available musical data, music can be played with similar tones.

SMF (Standard MIDI File):

SMF is a standard file format for MIDI instruments and computer music software. SMF formatted data can be played and transported easily among SMF complied instruments or musical data of different manufacturers.

DVDD

Initial reset When batteries are set or an AC adapter is connected, the reset IC provides a low pulse to the CPU. When the power switch is pressed, the CPU receives a low pulse of POWER signal. The CPU first raises APO signal to +5 V to generate DVDD voltage, then raises RESET signal to +5 V. During this period the DSP and the key controller LSI initialize their internal circuits.

POWER SUPPLY CIRCUIT

The power supply circuit provides various voltages as shown below. The voltage VDD (+5 V) is provided as long as batteries or AC adaptor is set. Other voltages are controlled by APO (Auto Power Off) signal from CPU.
