Chapter 8
 
PATCH
 
These parameters are set for each individual patch with the BASS TO 
MIDI function.
 
BASS TO MIDI
 
Parameter/
Range
Explanation
 
BASS TO MIDI
 
OFF, ON
This switches the BASS TO MIDI function 
on and off. Setting this to OFF prevents out-
put of all BASS TO MIDI-related MIDI mes-
sages.
 
Parameter/
Range
Explanation
 
MODE
 
This sets the transmission mode for the MIDI messages.
MONO
In this mode, one channel per string is used, 
thus using a total of six channels.
Since each string uses a different MIDI chan-
nel, you can select a different tone for each 
string, using string bending or continuously 
varying the pitch on a specific string; how-
ever, this requires use of a multitimbral 
sound module.
POLY
In this mode, the messages for all six strings 
are transmitted over a single channel.
While transmitting the MIDI messages for 
all of the strings over one channel does sim-
plify the settings needed for the sound mod-
ule and reduces the number of MIDI 
channels used, it does impose certain limita-
tions; for example, permitting only one tone 
to be selected for all of the strings.
 
PLAY FEEL
 
This selects the feeling produced in playing the bass, allowing you to 
choose playing with fingers or a pick to provide more natural dy-
namic expression.
FEEL1–4
FEEL1 is the mode that gives sounds the 
broadest variation in volume based on the 
playing dynamics. As the setting number is 
increased, it becomes easier to produce high 
volume sounds even with weaker playing.
This allows you to play with consistent vol-
ume, whether you tap the strings or use 
rough playing. In general, use higher setting 
numbers for softer playing, fingerplaying or 
tapping.
NO DYNA
In this mode, sounds are played at a fixed 
volume regardless of the playing strength.
STRUM
This suppresses the output of sounds from 
weaker playing.
This setting allows you to prevent undes-
ired sounds produced when playing 
rhythm or due to incidental contact with 
strings from incorrect playing.
 
Parameter/
Range
Explanation
 
CHROMATIC
 
This sets the VB-99 so that if you play bends or slides, the unit will 
not send pitch bend message but instead will play the notes in half 
steps.
OFF
Normal Pitch Bend messages are output. 
The pitch varies continuously in keeping 
with the string bending or vibrato.
TYPE1
When the pitch changes, this setting applies 
the results of the pitch change information 
without stopping the note that is playing.
This produces a unique effect, whereby 
there is no attack sound when the pitches 
change, similar to slurring on a clarinet or a 
saxophone.
TYPE2
When the pitch changes, the VB-99 retrig-
gers (replays) the sound at the changed 
pitch, producing pitch changes only at the 
semitone increments.
As a result, the attack of the new note starts 
at the current volume of the string, not the 
original volume.
TYPE3
As with CHROMATIC TYPE 2, sounds are 
retriggered at the changed pitch, expressing 
the pitch changes only in semitones.
However, instead of reflecting the attenua-
tion of the string vibration, the retriggered 
sound is the same as that when the string 
was initially played.
 
HOLD TYPE
 
This selects the way the Hold function works.
HOLD1
Note On messages are held when the Hold 
function is switched on with the controller.
If the Hold function remains on as you con-
tinue to play the strings, each successive 
Note On message is held, and when a Note 
message is already being played from the 
same string,
the previous Note message is cancelled, and 
the next Note On message is held. This al-
lows you to prevent any interruption in the 
sounds, even sounds from releasing the 
strings over the frets.
HOLD2
Note On messages are held when the Hold 
function is switched on with the controller.
However, subsequent Note On messages 
are not output if you continue to play the in-
strument with the Hold effect left on.
HOLD3
Note On messages are held when the Hold 
function is switched on with the controller.If 
the Hold function remains on as you contin-
ue to play the strings, Note On messages for 
strings other than the one already being 
held can be output, but they are not held.
