voice selector. Full details are given in the following pages.
Local Control ON/OFF
“Local Control” refers to the fact that, normally, the
PDP-300 keyboard controls its internal tone generator,
allowing the internal voices to be played directly from
the keyboard. This situation is “Local Control ON” since
the internal tone generator is controlled locally by its
own keyboard.
Local control can be turned OFF, however, so that the
PDP-300 keyboard does not play the internal voices, but the
appropriate MIDI information is still transmitted via the
MIDI OUT connector when notes are played on the keyboard.
At the same time, the internal tone generator responds to
MIDI information received via the MIDI IN connector. This
means that while an external MIDI sequencer plays the PDP-
300’s internal voices, an external tone generator can be
played from the PDP-300’s keyboard.

Turning Local Control ON or OFF

1. Hold down the [MIDI/TRANSPOSE] button.
2. Press the [PIANO 1] voice selector. If the PIANO 1
LED is lit when the [PIANO 1] voice selector is
pressed, you have turned local control OFF. If the PI-
ANO 1 LED is not lit when the [PIANO 1] voice se-
lector is pressed, you have turned local control ON.
3. Release the [MIDI/TRANSPOSE] button.
Program Change ON/OFF
Normally the PDP-300 will respond to MIDI program
change numbers received from an external keyboard or
other MIDI device, causing the correspondingly num-
bered PDP-300 voice to be selected. The PDP-300 will
normally also send a MIDI program change number
whenever one of its voices is selected, causing the corre-
spondingly numbered voice or program to be selected on
the external MIDI device if the device is set up to re-
ceive and respond to MIDI program change numbers.
This function makes it possible to cancel program
change number reception and transmission so that voices
can be selected on the PDP-300 without affecting the ex-
ternal MIDI device, and vice versa.
1. Hold down the [MIDI/TRANSPOSE] button.
2. Press the [PIANO 2] voice selector. If the PIANO 2
LED is lit when the [PIANO 2] voice selector is
pressed, you have turned program change reception/
transmission OFF. If the PIANO 2 LED is not lit when
the [PIANO 2] voice selector is pressed, you have
turned program change reception/transmission ON.
3. Release the [MIDI/TRANSPOSE] button.
Control Change ON/OFF
Normally the PDP-300 will respond to MIDI control
change data received from an external MIDI device or
keyboard, causing the selected PDP-300 voice to be af-
fected by pedal and other “control” settings received
from the controlling device. The PDP-300 also transmits
MIDI control change information when either of its ped-
als are operated.
This function makes it possible to cancel control change
data reception and transmission if you do not want the PDP-
300 voices to be affected by control change data received
from an external device or vice versa.
1. Hold down the [MIDI/TRANSPOSE] button.
2. Press the [CLAVINOVA TONE] voice selector. If the
CLAVINOVA TONE LED is lit when the [CLAVI-
NOVA TONE] voice selector is pressed, you have
turned control change reception/transmission OFF. If
the CLAVINOVA TONE LED is not lit when the
[CLAVINOVA TONE] voice selector is pressed, you
have turned control change reception/transmission
ON.
3. Release the [MIDI/TRANSPOSE] button.
The Multi-Timbre Mode
The Multi-Timbre mode is a special mode in which the
PDP-300 voices can be independently controlled on different
MIDI channel numbers by an external MIDI device. The
Multi-Timbre mode can be activated as follows:
1. Hold down the [MIDI/TRANSPOSE] button.
2. Press the [E.PIANO] voice selector. If the E.PIANO
LED is lit when the [E.PIANO] voice selector is
pressed, you have turned the Multi-Timbre mode ON.
If the E.PIANO LED is not lit when the [E.PIANO]
voice selector is pressed, you have turned the Multi-
Timbre mode OFF.
3. Release the [MIDI/TRANSPOSE] button.
Here’s an example of how you could use the Multi-
Timbre mode to record three different parts on a se-
quencer that will play different voices on the PDP-300
when played back.
1. Connect a sequencer to the PDP-300 as shown below.
2. Select the first voice and MIDI transmit channel num-
ber, then record the first part on the sequencer.
3. Activate the PDP-300 Multi-Timbre mode, then select a
new MIDI transmit channel and voice and record the sec-
ond part on the sequencer using its overdubbing function.
4. While still in the Multi-Timbre mode, select the third
MIDI transmit channel and voice and record the third
part on the sequencer using its overdubbing function.
5. Still in the Multi-Timbre mode, play back the se-
quencer. The recorded parts will be played back using
the individual voices selected during recording, pro-
viding a full ensemble sound.
