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 [<] and [>] 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 [<] and
[>] buttons can be used to select different param-
eters.
Press the [EXIT] button to return to the previous
display.
