SONGBOOK

Music-minus-one

This is a feature that plays the accompaniment to a selected

tune while you play a melody or ad-lib phrases on the

keyboard. The tunes are the same as the demo tunes, and are

selected in the same way.

Use the [SONG SELECT] buttons to select a song number

between "00" and "14."

Press the

button briefly to increment (increase by

one) the song number, or the

(decrease by one) the song number. Holding either button

causes continuous incrementing or decrementing. The

selected song number will be shown on the MULTI DIS-

PLAY while the SONG SELECT

pressed.

Press the [MINUS ONE START/STOP] button to start

playback of the selected song without the melody line.

When Minus One playback begins, the same voice as for the

corresponding demo melody is selected. The DUAL setting and

harmony type are also the same.

Play along on the keyboard.

Only the NORMAL and SPLIT modes can be used during mi-

nus-one playback. The NORMAL mode will automatically be

selected if FINGERED or SINGLE FINGER is engaged when

minus-one playback is started.

Playback will continue until the [MINUS ONE START/

STOP] button is pressed again.

If you press the [DEMO START/STOP] button during minus-one

playback, the melody part will reappear and playback will con-

tinue in the DEMO mode.

On the other hand, if you press the [MINUS ONE START/

STOP] button during demo playback, the melody part will be

muted and playback will continue in the MINUS ONE mode.

The following functions can be used during minus-one

playback:

MOVING UP TO MIDI

A Brief Introduction to MIDI

MIDI, the Musical Instrument Digital Interface, is a world-

standard communication interface that allows MIDI-compat-

ible musical instruments and equipment to share musical infor-

mation and control one another. This makes it possible to cre-

ate "systems" of MIDI instruments and equipment that offer

far greater versatility and control than is available with iso-

lated instruments.

The PSR-300 MIDI Connectors

The PSR-300 MIDI IN connector receives MIDI data from

an external MIDI device which can be used to control the

PSR-300. The MIDI OUT connector transmits MIDI data

generated by the PSR-300 (e.g. note and velocity data pro-

duced by playing the keyboard).

Simple MIDI Control

Most MIDI keyboards (including the PSR-300, of course)

transmit note and velocity (touch response) information via the

MIDI OUT connector whenever a note is played on the key-

board. If the MIDI OUT connector is connected to the MIDI

IN connector of a second keyboard (synthesizer, etc.) or a tone

generator (essentially a synthesizer with no keyboard), the

second keyboard or tone generator will respond precisely to

notes played on the original transmitting keyboard. The result

is that you can effectively play two instruments at once, pro-

viding thick multi-instrument sounds. The PSR-300 also trans-

mits "program change" data when one of its voices is selected.

Depending on how the receiving device is set up, the corre-

sponding voice will be automatically selected on the receiving

keyboard or tone generator whenever a voice is selected on the

PSR-300.

The PSR-300 is capable of receiving the same MIDI data,

so a second MIDI keyboard connected to the PSR-300 MIDI

IN connector can be used to remotely play the PSR-300 and

select voices as required.
