Unable to save SYSTEM/USB USB
IN settings
→ If the USB IN parameter is set to COSM BASS A, COSM
BASS B, or NORMAL PU, then MAIN & SUB will be set
the next time the VB-99 is powered up. If you plan to use
COSM BASS A, COSM BASS B, or NORMAL PU,
remake this setting each time you turn on the power to
the VB-99 (p. 152).
Patches not switching
❏ Is some screen other than the Play screen shown in the
display?
→ With the VB-99, you cannot switch patches in any screen
other than the Play screen. Press [EXIT] one or more
times to return to the Play screen (p. 20).
❏ Is [SYSTEM] - MISC - PATCH EXTENT set correctly?
→ The range of patches that can be selected is limited by
the PATCH EXTENT setting. Be sure to set this correctly.
Unable to control parameters set
with Assign as expected
❏ Are the effects switched off?
→ Check to make sure the effects incorporating the
parameters being controlled are on.
❏ Is the patch set to anything other than ASSIGNABLE
(PATCH) in [SYSTEM] - CONTROL ASSIGN?
→ Even with the patch’s [CONTROL ASSIGN] setting
made, the settings made in [SYSTEM] - CONTROL
ASSIGN are given priority.
To enable the settings in the patch, set the controllers
under [SYSTEM] - CONTROL ASSIGN to ASSIGNABLE
(PATCH).
❏ Are the MIDI channels matched?
→ When carrying out operations using MIDI, check to
confirm that both devices are set to the same MIDI
channel (p. 52).
❏ Are the controller numbers (CC#) matched?
→ Check to confirm that the controller numbers you are
using are the same (p. 56).

transmitted/received
❏ Could there be a short in the MIDI cable?
→ Try replacing the MIDI cable.
❏ Are the VB-99 and the external MIDI device connected
properly?
→ Check the connection with the external MIDI device.
❏ Are the MIDI channels matched?
→ Check to confirm that both devices are set to the same
MIDI channel (p. 52).
❏ Are the Device ID matched?
→ Check to confirm that both devices are set to the same
Device ID (p. 53).
❏ If you are transmitting from the VB-99, have the
settings for transmission been made?
→ Check the Program Change message transmission ON/
OFF setting (p. 54) and the settings for the controller
number to be transmitted (p. 56).
