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.
1.
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.
2.
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.
3.
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.
4.
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.
