MIDI Operations (MIDI Mode)
■ What is MIDI?
MIDI is the abbreviation for: Musical Instruments Digital Interface. MIDI
is a world standard communication interface that allows MIDI compat-
ible musical instruments and computers to share musical information
and control one another regardless of instrument type or maker. With
the DG-1000, an external MIDI controller can be used to recall memory
settings (program change), an external MIDI controller can be used to
control the main volume (control change), and memory and MIDI set-
tings can be exchanged with an external MIDI device (bulk dump).
■ Using MIDI to Recall Memory
Program change messages from a Yamaha MIDI Foot Controller MFC10,
etc., or external MIDI device can be used to recall settings in the DG-
1000’s memory.
1. Use a MIDI cable to connect the DG-1000’s MIDI IN Jack to the
MIDI OUT Jack on an external MIDI device.
* Use only a standard MIDI cable that is less than 15 meters in length.
Using a longer cable may result in abnormal operation.
* After the Main Volume data is changed, and the external MIDI device
is disconnected, the pre-amp’s volume level may not be sufficient. If this
case occurs, transmit a Control Change with a higher volume setting
again, or switch the POWER OFF and then back ON.
■ Setting the MIDI Merge
To have data received by the DG-1000’s MIDI IN jack, re-transmitted
from the MIDI OUT jack, set the MIDI Merge to “
on”. If not, set to “oF”.
1. Press the button, the MIDI Display will light.
2. Press the button, the current MIDI Merge setting is shown
in the display.
3. Use the / buttons to select “on/oF”.
■ MIDI Bulk Out
The DG-1000’s data can be sent to an external MIDI storage device
(Yamaha MIDI Data Filer MDF2, etc.) for data backup.
1. Use a MIDI cable to connect the DG-1000’s MIDI OUT Jack to the
MIDI IN Jack on an external MIDI device.
2. Press the button. The MIDI display lamp will light.
3. To send data for the entire memory (128) + MIDI settings with
the Bulk Out operation:
→ Press the button. “All” is shown in the display.
To send a single memory with the Bulk Out operation:
→ Press the button. Use the / buttons to
select the memory number you wish to send.
4. Press the button to transmit the memory data.
Press the button to cancel the operation.
* The device number is the same as the MIDI receive channel. If the
MIDI receive channel is set to OMNI ( All) or OFF ( oF ), the
MIDI channel will be set to 1.
■ MIDI Bulk In
Use a MIDI cable to connect the DG-1000’s MIDI IN Jack to the MIDI
OUT Jack on an external MIDI device. Return DG-1000 backup data to
the DG-1000.
* The MIDI bulk in operation is carried out in the PLAY or EDIT modes
only. It can not be carried out in the MIDI mode.
* The device number is the same as the MIDI receive channel. If the MIDI
receive channel is set to OMNI ( All ), the MIDI channel will be set to
1. It will not receive if it is set to OFF ( oF ).
*“Ld” is shown on the display during the MIDI Bulk In operation.
■ Error Messages
If an error occurs during a MIDI operation, one of the following error
message numbers will appear on the DG-1000’s display.
E2: MIDI receive buffer full.
Too much MIDI data is being received by the DG-1000 at one
time. Try to reduce the amount of data being sent or, break
the data into smaller blocks.
E3: Communication error.
An abnormality is detected in the transmitted data. Check all
connections and relevant settings and try again.
E4: Bulk receive check sum error.
A check sum error has been detected in the MIDI bulk data
received by the DG-1000. Check all connections and relevant
settings and try again.
E5: Bulk receive data abnormality.
An abnormality has been detected in the MIDI bulk data
rö”eived by the DG-1000. Check all connections and relevant
settings and try again.

2. Set the DG-1000’s MIDI receive channel and the external MIDI
device’s MIDI transmit channel to the same MIDI channel. (the
factory preset is channel 1).
2-1. Press the button, the MIDI display lamp will light.
2-2. Press the button, the currently set MIDI receive chan-
nel is shown on the display.
2-3. Use the / buttons to select the MIDI receive channel
(1 – 16 , All, oF).
* All is set to OMNI.
3. Create a program change table*
(the factory preset is, Program Change No. = Memory No.).
* For example, “the received Program Change Number 1, recalls the
DG-1000’s Memory Number 5”. To achieve this, assign the received
program change number to the corresponding memory number.
3-1. With the Mode Display Lamp lit, press the button.
3-2. Use the / buttons to select a program change number
(1 – 2.8). The selected number appears on the display.
3-3. Press the button.
3-4. Use the / buttons to select the corresponding memory
number (1 – 2.8). The number appears on the display.
3-5. If necessary, repeat steps 3-1 through 3-4.
4. When program memory data is transmitted from an external
MIDI device, the corresponding memory assigned to the Pro-
gram Change Table will be recalled.
■ About MIDI Control Changes
You can control the overall volume of the DG-1000 by connecting an
external MIDI device’s MIDI OUT jack to the DG-1000’s MIDI IN jack,
and transmit Number 7 Control Change Messages (Main Volume) to the
DG-1000.
* With the exception of the Number 7 Control Change, the DG-1000 does
not recognize any other MIDI Control Change messages.
* The Main Volume data will not change, even if a different memory num-
ber is selected.
* When the POWER is switched ON, the Main Volume data is set to its
MAX value.
