Easy to Use Functions
Using MIDI commands you can select memory numbers on the DG100-212, turn ON/OFF the reverb and tape echo effects, and
control volume. A speaker simulator can also be applied to the line out signal.
What is MIDI? MIDI is the acronym for Musical Instruments Digital Interface. MIDI is a world-wide standard communication interface
that allows MIDI compatible musical instruments, computers and other MIDI devices to share musical information and
control one another regardless of instrument type or maker.
■ Using MIDI to Recall Memory
Program changes sent from a Yamaha MIDI Foot Controller MFC10, etc., or
an external MIDI device can be used to recall settings in the DG100-212’s
memory.
1. With a MIDI cable, connect the DG100-212’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. Use of a
longer cable may result in abnormal operation.

1. Using procedures 1. and 2. in the previous “MIDI Memory Recall”
section, connect the external MIDI device and set the MIDI receive
channel.
2. Next, select the volume control position.
→ For instructions on the setting procedure, refer to page 11 “Set the
Volume Pedal Position”.
3. In this condition, number 7 control change data transmitted from
an external MIDI device will now control the DG100-212’s volume.
* The DG100-212 does not except MIDI control changes other than numbers
7, 91 and 94.
* For more information on transmitting control data, refer to your external
MIDI device’s owner’s manual.
* Even if another memory number is selected, main volume data will not change.
* When the power is switched ON, main volume data is set to its maximum
level.
* After the main volume data is changed, and the external MIDI device is
disconnected, the volume level may be insufficient. In this case, transmit the
volume change again or, turn the power OFF and then ON again.
■ Using MIDI to Turn ON/OFF the Reverb and
Tape Echo Effects
You can turn ON/OFF the DG100-212’s REVERB effect from an external
MIDI device using a number 91 MIDI control change message sent from the
MIDI OUT jack of an external MIDI device to the DG100-212’s MIDI IN jack.
In the same manner, a number 94 MIDI control change sent to the DG100-
212 will turn ON/OFF the DG100-212’s Tape Echo effect.
1. Using procedures 1. and 2. in the previous “MIDI Memory Recall”
section, connect the external MIDI device and set the MIDI receive
channel.
2. In this condition, number 91 or 94 control change data transmitted
from an external MIDI device will now turn ON/OFF the DG100-212’s
Reverb and/or Tape Echo.
* Regarding the DG100-212’s control change settings. A received control
change equal to or greater than 64 will result in an “ON” setting. Less than
or equal to 63 will result in an “OFF” setting. However, settings on the
transmission side device should be set to 127 for “ON” and 0 for “OFF”.
* For more information on transmitting control data, refer to your external
MIDI device’s owner’s manual.
■ Speaker Simulator
The DG100-212’s speaker simulator provides the line signal with a realistic
simulation of the natural sound of a speaker. The speaker simulator can be
used on the line signal when the LINE OUT jack is connected to a mixer or
recorder.
→ For setting instructions, refer to the “Speaker Simulator ON/OFF”
section in this manual.

2. Set the DG100-212’s MIDI receive channel and the MIDI transmit
channel on the external device to the same MIDI channel number
(the factory preset channel number is 1).
→ For setting instructions see page 11 “Set the MIDI Receive Chan-
nel”.
3. Create a program change table* 1 .(The factory preset is, program
change number = memory number).
→ For setting instructions see page 11 “Creating a Program Change
Table”.
* 1 For example, “the received program change number 1, recalls the DG100-
212’s memory number 5”. To achieve this, the received program change
number must be assigned to the corresponding memory number.
4. When program memory data is transmitted from an external MIDI
device, data in the corresponding memory assigned to the program
change table will be recalled.
* For instructions on how to transmit program change data, check the owner’s
manual of the external MIDI device you are using.
■ Using MIDI to Control Volume
You can control the DG100-212’s overall volume from an external MIDI de-
vice using a number 7 control change message (main volume) sent from the
MIDI OUT jack of an external MIDI device to the DG100-212’s MIDI IN jack.
By connecting a Yamaha MIDI Foot Controller MFC10, etc., or a MIDI device
equipped with a foot pedal, you can use the foot pedal to control the volume
during performance. Using the following three positions, you can select the
control position as to where the volume is changed.
• “ bP ” : Before Pre Amp. Controls the volume before the preamp.
• “ AP ” : After Pre Amp. Controls the volume after the preamp.
• “ Ar ” : After REVERB: Controls the volume after the reverb.
