Key Mode Alteration

The way in which the Key Mode (p. 2) affects how notes are
sounded differs depending on whether you're using the D-05 in
mono mode or in poly mode.

Mono Mode, Poly Mode

When you're using the D-05 from an external MIDI device, the D-05
can receive MIDI channels in the following two ways.
The D-05 can be used in one or the other of these two modes.
Name Function
Allows the control of more than one Key message on one
channel at a time.
Poly Mode
The D-05 is 16 or 8 voices polyphonic (depending on the
patch used). So the Poly Mode can be used the D-05 is
controlled by a keyboard or sequencer.
Allows only one MIDI massage on one channel. The D-05 is
8 voices polyphonic using 8 MIDI channels. The Mono
mode is ideal for a MIDI Guitar System (GR-55, etc.) hat has
Mono Mode Mono mode, and transmits the messages of each string
separately on a different channel. In the other words, Mono
mode makes it possible to reproduce guitar sounds without
spoiling the natural characteristics of the instrument.
Select Poly or Mono mode depending on the type of Mode
Message sent from the external MIDI device.
When Mono mode messages are received by the D-05, the
messages can now be received on a channel group (= eight
consecutive MIDI channels, the basic channel being the lowest
number).
* The Mono mode of the D-05 allows it to receive only the note and
bender messages for each channel, therefore it is NOT possible to
set a different sound for each note separately.
