Yamaha VL70-m User Manual

• 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.

• 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.

• 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.
