50 MIDI Functions

■MIDI Clock Select
This function determines whether the PDP-400’s rhythm and ABC timing is controlled by the PDP-400’s own inter-
nal clock or an external MIDI clock signal received from external equipment connected to the MIDI IN connector. The
Clock Mode is automatically set to INTERNAL when the power is initially turned on.
ZHold [MIDI/TRANSPOSE] and press the [ORGAN].
XRelease [MIDI/TRANSPOSE].
NOTES
•If the Clock Mode is set to EXTERNAL and a MIDI clock signal is not being received
from an external source, the rhythm, ABC and other clock-dependent features will not
operate.
■MIDI Transpose Transmit
This function transposes the pitch of transmitted MIDI note data up or down in semitone intervals up to a maximum
of six semitones. The pitch of notes played on the keyboard is not affected.
ZHold [MIDI/TRANSPOSE] and press [UPRIGHT BASS].
XUse the TEMPO [▲] and [▼] buttons to select the desired degree of transposition
while holding the [MIDI/TRANSPOSE] button.
The amount of transposition selected is shown on the TEMPO display.
CRelease [MIDI/TRANSPOSE].
NOTES
•Press the TEMPO [
▲
] and [
▼
] buttons simultaneously while holding the [MIDI/
TRANSPOSE] button to restore normal transmitted pitch.
•Transpose is always set to Normal when the power is turned on.
This function causes all the current PDP-400 panel settings (selected voice, etc) to be transmitted via the MIDI OUT
connector. This is particularly useful if you will be recording performances to a MIDI sequence recorder which will be
used to control the PDP-400 on playback. By transmitting the PDP-400 panel settings and recording them on the MIDI
sequence recorder prior to the actual performance data, the PDP-400 will be automatically restored to the same settings
when the performance is played back.
ZHold [MIDI/TRANSPOSE] and press [CHOIR].
XRelease [MIDI/TRANSPOSE].

■The DOC Common Voice Mode
This mode is similar to the Multi-Timbre Mode described on page 49, but MIDI program change numbers received
on all channels are converted to Yamaha DOC Common Voice Numbers. MIDI program change numbers transmitted
when the panel voice selectors are operated are also converted to the common voice numbers.
The DOC Common Voice mode is always off when the power is initially turned on. It can be activated as follows:
