The Utility Mode
The UTILITY mode provides access to a range of parameters that affect basic
operation of the VL70-m, and some functions that contribute to system flexibil-
ity. Select the UTILITY sub-mode menu from the PLAY mode by pressing the
[UTILITY] button. Four sub-modes are available:
The SYSTEM sub-mode includes parameters that affect overalloperation of the VL70-m. Page 98.
The Dump Out function allows VL70-m setup and system
exclusive data to be transmitted to a second VL70-m or an
external MIDI storage device such as the Yamaha MDF2 MIDI
Data Filer via the MIDI OUT or TO HOST connector. Page 100.
The VL70-m Initialize function includes two sub-modes —
“Factory Set” and “System Initialize”. “Factory Set” initialization
restores all VL70-m data to the initial factory settings … includ-
ing all Custom and Internal voices. “System Initialize” restores all
system setup parameters (page 98) to their default settings.

A “demonstration” function demonstrates some of the VL70-m
voices and capabilities. The DEMO function is described in detail
on page 24. SYSTEM

The System Parameters
The UTILITY SYSTEM sub-mode includes parameters that affect overall operation of the VL70-
m.
M.Tune
•Master Tuning
•Settings: -102.4c … +102.3c
Fine tunes the overall pitch of the VL70-m in 0.1-
cent steps (a “cent” is 1/100th of a semitone). The
maximum minus and plus settings produce a
downward or upward pitch shift of just over a
semitone. A setting of “+000.0” produces no pitch
change.
RcvSysExcl
•System Exclusive Receive
•Settings: off, on
This parameter determines whether or not the
VL70-m will receive MIDI system exclusive
messages. System exclusive data is received when
this parameter is “on”, and ignored when this
parameter is “off”.
TransmitCH
•MIDI Transmit Channel
•Settings: 1 … 16
Selects the MIDI channel via which data corre-
sponding to operation of a breath controller
connected to the VL70-m will be transmitted.
WX Lip
•WX Lip Mode
•Settings: Norm, Expd
WX-series Wind MIDI Controllers produce pitch
bend data ranging from “-16” to “+32” in response
to lip (reed) pressure. The “WX Lip” parameter
determines whether these values are used as is
(“Norm”), or expanded to a full “-64” through
“+63” range (“Expd”). When the “Expd” mode is
selected, the expanded pitch bend data is also
transmitted via the MIDI OUT and TO HOST
connector. The “Expd” setting is recommended
when using a WX controller in the “tight lip”
mode. The “Norm” setting is recommended when
using the WX controller “loose lip” mode.
WX LipLock
•WX Lip Lock
•Settings: off, on
When this parameters is “off” the VL70-m “WX
Lip” parameter (above) will be automatically set to
“Norm” whenever a MIDI “XG SYSTEM ON” or
“VOICE MODE ON” message is received. Turn
this parameter “on” if you do 
not want received
MIDI messages to affect the “WX Lip” setting.
The Utility Mode 
						

							99
Contrast
•Display Contrast
•Settings: 1 … 8
Sets the contrast of the VL70-m display for
optimum visibility. The best setting will depend on
your viewing angle and the ambient lighting
conditions. A setting of “1” produces the strongest
contrast, while a setting of “8” produces the
“softest” contrast.
DumpIntrval
•MIDI Bulk Dump Interval
•Settings: 50, 100, 150, 200, 300
Sets the length of time intervals to be inserted
between data blocks during a “Dump Out” opera-
tion (page 100). The required interval will depend
on the receiving MIDI device. The settings are in
milliseconds: i.e. 50 milliseconds, 100 millisec-
onds, etc. Try adjusting this parameter if the
receiving MIDI device generates an error message
while receiving a bulk dump from the VL70-m.
NoteFilter
•MIDI Note Filter
•Settings: ch01 … ch16, Thru
This parameter can be used to prevent MIDI note
on/off messages received on the specified channel
from being re-transmitted via the MIDI OUT
connector. Select the channel to be filtered out, or
“Thru” to allow all data to pass.• When the VL-XG sound module mode is
selected and a program change number correspond-
ing to a VL70-m voice is received, the “NoteFilter”
parameter is automatically set to the channel on
which the program change number was received.
This does 
not occur in the VOICE sound module
mode.
• When the VL70-m MIDI receive channel is
changed via the panel controls (pages 34 and 38),
the “NoteFilter” parameter is automatically set to
the same channel if it is initially set to 01 … 16,
but not when it is set to “Thru”. This does not
occur when the MIDI receive channel is changed
via a MIDI system exclusive message.
The Utility Mode 
						

							100
The Dump Out Function
The Dump Out function allows VL70-m setup and system exclusive data to
be transmitted to a second VL70-m or an external MIDI storage device such
as the Yamaha MDF2 MIDI Data Filer via the MID OUT or TO HOST connec-
tor.

 NOTES
• The MIDI Device Number of the receiving device must the same as that set via the VL70-
m PLAY mode “DevNo.” parameter (pages 32 and 41).
• You might have to try a few different DumpIntrval parameter (page 99) settings before
the receiving device will receive the data from the VL70-m without errors.
 DUMPOUT Operation
When the DUMPOUT sub-mode is selected from the UTILITY mode menu, a
second menu appears which allows you to choose the type of data to be trans-
mitted: SYSTEM, CURRENT, CUSTOM, or INTERNL. From this menu:
All “system” data, including system setup and breath settingdata.
Transmits the currently selected voice (i.e. the voice that was
selected immediately prior to engaging the UTILITY mode).
Transmits all 6 CUSTOM bank voices, or a single specified
CUSTOM bank voice. When “ALL” is selected all 6 CUSTOM
voices are transmitted, and when “C1” through “C6” is selected
the corresponding single CUSTOM voice is transmitted.
Transmits all 64 INTERNAL bank voices, or a single specified
INTERNAL bank voice. When “ALL” is selected all 64 INTERNAL
voices are transmitted, and when “I01” through “I64” is selected
the corresponding single INTERNAL voice is transmitted. SYSTEM

Show Control Change
This function displays the MIDI control change
data string required to control the parameter
currently displayed in the PLAY mode from an
external MIDI device. The MIDI data is displayed
in hexadecimal format.
To engage the Show Control Change function first
select the desired parameter in the PLAY mode,
then “double click” the [ENTER] button (i.e. press
the [ENTER] button twice in rapid succession).
The Show Control Change display will appear.
Show Exclusive
This function displays the MIDI system
exclusive data string required to control the
currently-displayed parameter from an external
MIDI device. The MIDI data is displayed in
hexadecimal format.
To engage the Show Exclusive function first select
the desired parameter, then “double click” the
[ENTER] button (i.e. press the [ENTER] button
twice in rapid succession). The Show Exclusive
display will appear.
Depending on the selected parameter, control
change data may be displayed in place of system
exclusive data. This variation is described in the
preceding section: “The Show Control Change
Function”.
While the Show Exclusive function is engaged the
VALUE [-] and [+] buttons can be used to change
values, and the SELECT [] buttons can
be used to select different parameters.
Press the [EXIT] button to return to the previous
display.
With the VL70-m it is possible to control just
about any parameter via MIDI system exclusive
messages from an external MIDI device. This
makes it possibe, for example, to change filter or
EG settings while playing, to change the sound as
required. You could also change effect settings, the
pitch of individual drum instruments, or just about
any ohter parameter to add life and variety to your
music. Until now, however, the process of using
this capability has been rather tedious: find the
required parameter in the MIDI documentation,
figure out what data string is required to perform
the desired operation, and so on. The VL70-m
Show Exlusive function shows the required data
string for the selected parameter immediately. Depending on the selected parameter, system
exlusive data may be displayed in place of control
change data. This variation is described in the next
section: “The Show Exclusive Function”.
While the Show Control Change function is
engaged the VALUE [-] and [+] buttons can be
used to change values, and the SELECT [] buttons can be used to select different param-
eters.
Press the [EXIT] button to return to the previous

The Message Window
The VL70-m Message Window function makes
it possible to display text messages up to 32
characters in length on the VL70-m display in the
PLAY mode. The messages can be transmitted in
the form of a data string from an external MIDI
device, and will appear on the VL70-m display for
about 3 seconds. A message could be placed at the
beginning of a song data file, for example, so that
the title of the song and other information appears
on the display at the beginning of the song.
Message

 Message Window Data Format
The format for message window data is as follows
(hexadecimal format):
F0 43 1n 4C 06 00 00 xx xx .... xx xx F7
“n” is the device number minus one. If the VL70-
m device number is set to “1”, for example, “n”
should be “0”.
“xx xx .... xx xx” is the text data. Each character is
represented by a single ASCII -code byte (2
hexadecimal digits). Refer to the chart below for
the ASCII code for each displayable character. The
numbers in the top row are the first digit and the
numbers in the leftmost column are the second
digit in the byte representing each character. The
capital letter “A”, for example, is represented by
hexadecimal byte “41”.

Bitmap Window
The VL70-m Bitmap Window function makes
it possible to display 16 x 16 dot icons and
simple animation sequences on the VL70-m
display in the PLAY mode. The bitmap data can be
transmitted in the form of a data string from an
external MIDI device, and will appear on the
VL70-m display for about 3 seconds.

 Bitmap Window Data Format
The format for message window data is as follows
(hexadecimal format):
F0 43 1n 4C 07 00 00 xx xx .... xx xx F7
“n” is the device number minus one. If the VL70-
m device number is set to “1”, for example, “n”
should be “0”.
“xx xx .... xx xx” is the bitmap data consisting of a
string of 48 2-digit hexadecimal bytes.

 Creating Bitmap Data
1. Block out the desired design on a 16 x 16
grid, as shown in the example below.
2. Filled squares will be represented by ones,
and empty squares by zeroes.

3. Divide the design horizontally into three
sections: two seven-columns and one two-
columns in width. Add one column of squares
the left of each section, and 5 columns to the
right of the 2-column section, as shown in
the example below. You now have 48 rows,
each 8 columns in width.
4. Use the chart below to convert the ones and
zeroes in each row from binary format to
hexadecimal format. The “bits” in columns 0
through 3 become the first digit, and the bits
in columns 4 through 7 become the second
digit of each hexadecimal byte.
For example, the 11th row in the example
forms the binary byte:” “01000011”. Columns 0
through 3 form “0100”, which, using the chart,
becomes hexadecimal digit “4”. Columns 4
through 7 form “0011”, which, using the chart,
becomes hexadecimal digit “3”. The 11th row
in the design can therefore be represented by
hexadecimal byte “43”.

After converting all 48 rows in the example we
have the following hexadecimal bytes:Checksum
Some VL70-m system exclusive message
require a “checksum” — a data byte which is
used to check for errors during MIDI data transfer.
The checksum is calculated using the system
exclusive message start address and data (data
size). A method of calculating the checksum is
given below, using a simple data format as an
example.
1. Convert the hexadecimal start address and
data bytes (underlined in the example) to
decimal format using the chart below. Each
two-digit hexadecimal byte becomes a
decimal number.
• “mm”, the Model ID, is “57” when the VOICE
sound module mode is selected, and “4C” when
the VL-XG sound module mode is selected.
5. Plug the data derived from the bitmap design
into the “xx xx .... xx xx” portion of the
bitmap window data format, and you have
the data stream required to display the
design on the VL70-m display.
