MIDI Functions
■ The Multi-Timbre Mode
The Multi-Timbre mode is a special mode in which the PDP-400 voices can be independently controlled on different
MIDI channel numbers (1 through 15) by an external MIDI device. The Multi-Timbre mode is off when the power is
initially turned on.
The Multi-Timbre mode can be activated as follows:
ZHold [MIDI/TRANSPOSE] and press [GUITAR].
XRelease [MIDI/TRANSPOSE].
In this mode MIDI program change numbers received by the PDP-400 select the
corresponding PDP-400 voices — i.e. the same voices selected by the panel con-
trols. The DOC Common Voice Mode described on page 50 also allows multi-tim-
bre control of the PDP-400, but with different voice assignments.
● Rhythm Instrument Note Assignments

■ The Split Send Mode
In the split send mode notes played on the left-hand section of the keyboard (to the left of and including the split
point key — see “Changing the Split Point” on page 10) are transmitted on MIDI channel 2, while the upper keyboard
section transmits on the MIDI channel set using the Send Channel Select function described earlier. In this mode the left-
and right-hand sections of the keyboard can be used to play separate external keyboards or tone generators set to receive
on the appropriate channels. The Split Send Mode is automatically turned off when the power is initially turned on.
ZHold [MIDI/TRANSPOSE] and press [STRINGS].
XRelease [MIDI/TRANSPOSE].
