TROUBLESHOOTING

If you encounter what appears to be a malfunction, please check

the following points before assuming that your Personal Elec-

tronic Piano is faulty.

1. No Sound When the Power is Turned ON

Is the AC plug properly connected to an AC wall outlet?

Check the AC connection carefully. Is the MASTER VOLUME

control turned up to a reasonable listening level?

2. The Personal Electronic Piano Reproduces Radio or TV

Sound

This can occur if there is a high-power transmitter in your

vicinity. Contact your Yamaha dealer.

3. Intermittent Static Noise

This is usually due to turning ON or OFF a household appli-

ance or other electronic equipment which is fed by the same

AC mains line as your Personal Electronic Piano.

4. Interference Appears On Radio or TV Sets Located Near

the Personal Electronic Piano

The Personal Electronic Piano contains digital circuitry which

can generate radio-frequency noise. The solution is to move

the Personal Electronic Piano further away from the affected

equipment, or vice versa.

5. Distorted Sound When the Personal Electronic Piano is Con-

nected to An External Amplifier/Speaker System

If the Personal Electronic Piano is connected to a stereo

system or instrument amplifier and the sound is distorted,

reduce the setting of the Personal Electronic Piano volume

control to a level at which the distortion ceases.

MIDI DATA FORMAT

If you're already very familiar with MIDI, or are using a com-

puter to control your music hardware with computer-generated

MIDI messages, the data provided in this section can help you

to control the Personal Electronic Piano.

1. NOTE ON/OFF

Data format: [9nH]–›[kk]–›[vv]

9nH = Note ON/OFF event (n = channel number)

kk = Note number (28~103=E

vv = Velocity (Key ON = 1~127. Key OFF= 0)

* Note OFF event format [8nH]–›[kk] also recognized (reception

only).

2. CONTROL CHANGE & MODE MESSAGES

Data format: [BnH]–›[cc]–›[dd]

BnH = Control event (n = channel number)

cc = Control number (or mode message number)

dd = Control value

4. SYSTEM REALTIME MESSAGES

Active Sensing (FEH)

Transmitted every 200 milliseconds. If not received for more than 400

milliseconds a NOTE OFF occurs.

5. SYSTEM EXCLUSIVE MESSAGES

Data format: [F0H]–›[43H]–›[xn]–›[ff] ..................... [F7H]

x=0, ff=7CH: Panel data dump. Panel data follows 7CH.

x=2, ff=7CH: Panel data request transmission.

Data format: [F0H]–›[43H]–›[73H]–›[20H]–›[nn]–›[F7H]

43H = YAMAHA ID

73H = SINGLE KEYBOARD ID

20H = YPP-50 ID

nn = 40H: Performance play ON (receive only)

nn = 41H: Performance play OFF (receive only)

nn = 50H: Tempo UP

nn = 51H: Tempo DOWN

nn = 52H: Tempo 120

6. MULTI TIMBRE MODE

Data format: [F0H]–›[43H]–›[73H]–›[id]–›[nn]–›[F7H]

43H = YAMAHA ID

73H = SINGLE KEYBOARD ID

id=0lH (Standard), 1BH (Clavinova), or 20H (YPP-50)

nn=15H: MULTI TIMBRE mode ON; nn=13H: MULTI TIMBRE

mode OFF; nn=7nH: Receive channel change (n = channel number.

Receive only).
