VDF MG (CTRL#2)
VDF Modulation messages [BnH,02H,vv] (Controller #02, vv:Depth of modulation) are used to
adjust the depth of the wah effects. This depth corresponds to the amount of the joystick’s
downward movement (in the –Y direction) on the MIDI keyboard. Some MIDI keyboards have a
wheel or lever type controller instead of a joystick to which you assign this function.
These VDF Modulation messages adjust only the depth of wah. Usually, the rate and type
(waveform) of wah are determined by the settings on the reception device. On the X5DR, you can
set the type and rate of wah using VDF MG in Program Edit mode.
How to trigger VDF MG messages varies depending on the keyboard you are using. (e.x.: Breath
control)
Foot Controller (CTRL#4)
Foot Controller messages [BnH,04H,vv] (Controller #04, vv:Value) are used to transmit a foot
controller’s movement. These messages are used to switch scales on the X5DR. When the value
vv is 0–63, the Main scale is selected, and when the value vv is 64–127, the Sub scale is selected.
Data Entry (CTRL#6/38)
Data Entry messages [BnH,06H,mm] (Controller #06, mm:Upper digits of the value)
[BnH,26H,vv] (Controller #38, vv: Lower digits of the value) are used to set the parameter value
using the RPN. For details, refer to the section on RPN (page 71).
Volume (CTRL#7)
Volume messages [BnH,07H,vv] (Controller #07, vv:Value) are used to adjust the volume level.
The range of the value “vv” is 0 through 127. Usually, these messages are used to adjust the
volume level balance for multi-timbral performances.
The actual volume level is obtained by the volume value multiplied by the Expression (Controller
#11) value. [Volume level = The volume setting (such as the OSC level)

Panpot (CTRL#10)
Panpot messages [BnH,0AH,vv] (Controller #10, vv:Value) are used to adjust the panpots for
stereo playback. These messages correspond to Panpot A-B on the X5DR. Refer to the chart on
page 173 for the relationship between the panpot value (vv) and responses.
These messages are ignored when the Pan setting of the Timbre in Combination mode or Track in
Multi mode is OFF or PRG. They are also ignored in Program mode.
Expression (CTRL#11)
Expression messages [BnH,0BH,vv] (Controller #11, vv:Value) are used to adjust the volume
level. The range of value “vv” is 0 through 127. Usually, these messages are used to create
crescendos and diminuendos. Usually, Volume messages (Controller #7) are used to control the
level of the musical data in its entirety (i.e., the volume balance between different instruments or
parts).
The actual volume level is obtained by the volume value (Controller #7) multiplied by the
Expression value. [Volume level = The volume setting (such as the OSC level)

Effect Control 1/2 (CTRL#12/13)
Effect Control 1 [BnH,0CH,vv] (Controller #12, vv:Value) and Effect Control 2 [BnH,0Dh,vv]
(Controller #13, vv:Value) messages are used as modulation sources to adjust the effects. On the
X5DR, Effect Control 1 corresponds to Pedal 1, and Effect Control 2 corresponds to Pedal 2.

These messages are received only on the Global MIDI Channel.
