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.

• 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 (mak-

ing 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.

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 manufac-

turers.

MEMORY DEVICES

Each memory device has the following data.

1RAM1 :

S-RAM for operation program, Register, Pattern and

Song. (Upper part of data bus)

2Internal ROM of CPU :

Main program data for system operation

3Internal RAM of CPU :

Work area for system operation

4ROM1 :

Demo, Accompaniment data, Song, Pattern, Synth mode

5ROM2 :

Sound Waveforms/Tone data Digital sound effect

6Working RAM :

Work area for DSP

Initial reset

When batteries are set or anAC 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.
