Chapter 5 Using MIDI
Thinning Out Bend Messages (BEND THIN)
Vibrato, slides, and other such data in bass performances are output
as Pitch Bend messages. For this reason, the receiving MIDI device
may encounter problems with operation when Pitch Bend messages
containing large amounts of data are included.
You can use the BEND THIN function to thin out the Pitch Bend
messages and control the volume of MIDI data.
1. Follow Steps 1–2 in “Selecting the Controller
Used to Control the Hold Function (HOLD
CTL)” (p. 59) to display the BASS TO MIDI
screen.
2. Set the function to ON with [F2] (OFF/ON) or
the F2 knob.
Select OFF when you do not want to reduce the amount of
data transmitted in the Pitch Bend messages.
Setting the MIDI Transmit Channel
(BASIC CH)
This sets the MIDI channel used for output of string performance
data from the VB-99.
Set the MIDI channels according to the POLY/MONO mode as
shown below.
• When set to POLY mode
The performance data for all of the strings is transmitted over
the basic channel.
• When set to MONO mode
Hi C string: Transmitted over the basic channel.
1st string: Transmitted over the channel number one higher
than the basic channel.
:
Low B string: Transmitted over the channel number five
higher than the basic channel.
For more details about the mode, refer to “Setting the
Transmission Mode (MODE)” (p. 61).
1. Follow Steps 1–2 in
“Selecting the Controller
Used to Control the Hold Function (HOLD
CTL)” (p. 59) to display the BASS TO MIDI screen.
2. Set the channel with [F3] (SELECT) or the F3
knob.
Preventing Transmission of Program
Change Messages (PC MASK)
You can prevent transmission of Program Change messages that can
be set in “Outputting Program Change Messages
Simultaneously When Switching Patches (PC)” (p. 64).
* This does not affect such Program Changes as those set in “MIDI PC
OUT” (p. 54).
1. Follow Steps 1–2 in “Selecting the Controller
Used to Control the Hold Function (HOLD
CTL)” (p. 59) to display the BASS TO MIDI
screen.
2. Set the function to ON with [F4] (OFF/ON) or
the F4 knob.
When PC MASK is set to ON, the Program Change messages
set with the PC parameter (p. 64) in BASS TO MIDI are not
transmitted.
