“SendCho→Rev” parameter (page 91) can be used to send some or all of the
output from the chorus stage to the reverb stage. If the the “SendCho→Rev”
parameter is set to maximum and the “ChoRtn” parameter is set to “000”, the
chorus stage and reverb stage are effectively connected in series.

 generator
In this case the output from the tone generator is first sent to the distortion
stage, and the distortion effect signal is then mixed back into the main signal
line via the corresponding “Dry/Wet” parameter. In this connection mode only
the distortion stage is functioning as an insertion effect. After the distortion
stage the signal can be sent to the reverb, chorus and variation stages via the
“RevSend”, “ChoSend”, and “VarSend” parameters available in the PLAY mode
(pages 35 and 39). The output from all three of these stages is stereo, and the
effect signal can be mixed back in with the main signal line via the “RevRtn”,
“ChoRtn”, and “VarRtn” parameters available in the PLAY mode (pages 32, 33
and 41). The “SendCho→Rev” parameter (page 32) can be used to send some
or all of the output from the chorus stage to the reverb stage. If the
“SendCho→Rev” parameter is set to maximum and the “ChoRtn” parameter is
set to “000”, the chorus stage and reverb stage are effectively connected in
series. The “SendVar→Rev” and “SendVar→Cho” parameters (page 93) can be
used to send some or all of the output from the variation stage to the reverb and
chorus stages, respectively.

Type-Specific Variation  Parameters
•See separate “List Book”
Each of the variation types, selected via the “Type”
parameter, above, has a different set of parameters
that specify the actual variation effect sound. Refer
to the separate “List Book” for information on the
individual parameters for each variation type.
AT VarCtrl
•Aftertouch Variation Control
•Settings: -64 … +63
This parameter only becomes available when the
“VarConnect” parameter (page 93) is set to “INS”
(i.e. when the variation stage is connected as an
insertion effect). Aftertouch variation control
allows one of the selected variation effect param-
eters to be controlled in real time via keyboard
aftertouch pressure. The parameter which can be
controlled is individually preset for each variation
effect type (see the separate “List Book”). The “AT
VarCtrl” parameter determines to what degree the
effect parameter is affected by aftertouch pressure.
For example, if the TREMOLO effect is selected
aftertouch controls the “LFO Frequency” param-
eter. In this case higher positive “AT VarCtrl”
values cause increased aftertouch pressure to
increase the LFO speed, while higher negative
values cause increased aftertouch pressure to
decrease the LFO speed. If this parameter is set to
“+00” aftertouch control has no effect.
AC1VarCtrl
•Assignable Controller 1 Variation Control

higher the value, the more variation signal is sent
to the chorus stage. If this parameter and the PLAY
mode “VarRtn” parameter are both set to values
higher than “001”, the output of the variation stage
will be sent in corresponding amounts to the input
of the chorus stage and the main outputs. This
parameter becomes available when the
“VarConnect” parameter is set to “SYS” (i.e. when
the variation stage is connected as a system effect.)
SendVar➔Rev
•Variation-to-Reverb Send Level
•Settings: 000 … 127
Sets the amount of signal sent from the output of
the variation effect stage back to the input of the
reverb effect stage (see diagram on page 87). The
higher the value, the more variation signal is sent
to the reverb stage. If this parameter and the PLAY
mode “VarRtn” parameter are both set to values
higher than “001”, the output of the variation stage
will be sent in corresponding amounts to the input
of the reverb stage and the main outputs. This
parameter becomes available when the
“VarConnect” parameter is set to “SYS” (i.e. when
the variation stage is connected as a system effect.)
VarConnect
•Variation Connection Mode
•Settings: INS, SYS
Determines whether the variation effects stage
functions as an insertion effect (“INS”) or as a
system effect (“SYS”). See the diagrams and
explanations on pages 86 and 87 for the difference
between these connection modes. control allows one of the selected variation effect
parameters to be controlled in real time via assign-
able controller 1 (page 54). The parameter which
can be controlled is individually preset for each
variation effect type (see the separate “List Book”).
The “AC1VarCtrl” parameter determines to what
degree the effect parameter is affected by the
controller. For example, if the TREMOLO effect is
selected the controller affects the “LFO Frequency”
parameter. In this case higher positive
“AC1VarCtrl” values cause increased controller
settings to increase the LFO speed, while higher
negative values cause increased controller settings
to decrease the LFO speed. If this parameter is set
to “+00” assignable controller 1 has no effect.
Var Pan
•Variation Pan
•Settings: L63 … C … R63
Sets the pan position of the variation effect sound
— i.e. the perceived position of the variation effect
sound within the stereo sound field. A setting of
“L63” sets the variation sound full left, “R63” sets
the sound full right, and “C” places the sound in
the center. Intermediate settings pan the variation
effect sound to corresponding positions in the
stereo sound field. This parameter becomes avail-
able when the “VarConnect” parameter is set to
“SYS” (i.e. when the variation stage is connected
as a system effect.)
SendVar➔Cho

The Distortion Parameters
Distortion is an excellent way to drastically change a sound — although subtle distortion settings can
produce surprisingly delicate variations.
Type
•Distortion Type
•Settings: THRU, DISTORTION, OVERDRIVE, 3-BAND EQ
Selects the distortion type, or “THRU” if no
distortion effect is required. Refer to the separate
“List Book” for brief descriptions of each of the
distortion types.
Type-Specific Distortion Parameters
•See separate “List Book”
Each of the distortion types, selected via the
“Type” parameter, above, has a different set of
parameters that specify the actual distortion sound.
Refer to the separate “List Book” for information
on the individual parameters for each distortion
type.
AT DstCtrl
•Aftertouch Distortion Control
•Settings: -64 … +63
Aftertouch distortion control allows one of the
selected distortion effect parameters to be con-
trolled in real time via keyboard aftertouch pres-
sure. The parameter which can be controlled is
individually preset for each distortion effect type
(see the separate “List Book”). The “AT DstCtrl”
parameter determines to what degree the effect
parameter is affected by aftertouch pressure. Forexample, if the OVERDRIVE effect is selected
aftertouch controls the “Drive” parameter. In this
case higher positive “AT DstCtrl” values cause
increased aftertouch pressure to increase the
amount of drive, while higher negative values
cause increased aftertouch pressure to decrease the
amount of drive. If this parameter is set to “+00”
aftertouch control has no effect.
AC1DstCtrl
•Assignable Controller 1 Distortion Control
•Settings: -64 … +63
Assignable Controller variation control allows one
of the selected distortion effect parameters to be
controlled in real time via assignable controller 1
(page 54). The parameter which can be controlled
is individually preset for each distortion effect type
(see the separate “List Book”). The “AC1DstCtrl”
parameter determines to what degree the effect
parameter is affected by the controller. For ex-
ample, if the OVERDRIVE effect is selected the
controller affects the “Drive” parameter. In this
case higher positive “AC1DstCtrl” values cause
increased controller settings to increase the amount
of drive, while higher negative values cause
increased controller settings to decrease the amount
of drive. If this parameter is set to “+00” assign-
able controller 1 has no effect.

The Breath Parameters
Breath Mode
•Settings: BC/WX, Velocity, Touch EG
Sets the control source to be used for “breath”
control. This parameter should be set to “BC/WX”
when a breath controller or Yamaha WX-series
Wind MIDI Controller is being used (page 18).
When set to “Velocity”, breath variation is con-
trolled by keyboard initial touch response. When
“Touch EG” is selected breath variation is con-
trolled by a combination if initial keyboard touch
response and aftertouch pressure. Initial key
velocity sets the initial breath level, then aftertouch
pressure determines the shape of the subsequent
breath envelope.
• The icon of the “Breath Mode”, “Breath
Control” and “Breath Setting Lock” parameters
indicates which “Breath Mode” parameter
setting is selected.
Breath Control
•Settings: BC, Exp
Specifies the MIDI control change number to be
used for breath control when breath control is
applied from a breath controller, WX-series Wind
MIDI Controller, or via the VL70-m MIDI IN
connector. When “BC” is selected control change
number “02” (breath control) is used for breath
copntrol. When “Exp” is selected control change
number “11” (expression) is used for breath
control. This setting also affects both MIDI and
HOST output from the VL70-m.
Breath Curve
•Settings: -16 … +16
Determines the relationship between breath control
data received from a breath controller, WX-series
Wind MIDI Controller, or via the MIDI IN connec-
tor, and the actual amount of breath variation
applied. Minus settings result in a large breath
variation with a relatively small amount of breath
pressure applied to the controller, while plus
settings required a greater range of input breath
control values to produce the same degree of
breath variation. The graph at the bottom of the
display represents this relationship: the horizontal
axis is input breath pressure and the vertical axis is
actual breath variation.
Breath Setting Lock
•off, on
When this parameters is “off” the VL70-m “Breath
Mode” parameter (above) will be automatically set
to “BC/WX” whenever a MIDI “XG SYSTEM
ON” or “VOICE MODE ON” message is received.
At the same the “Breath Control” parameter
(above) is set to “BC” and the “Breath Curve”
parameter (also above) is set to +00. Turn this
parameter “on” if you do 
not want received MIDI
messages to affect the breath setting parameters.
