The display indicates “BATTERY LOW”
when power is turned on
➝ The internal battery that preserves the patch and system
parameters has run low. The battery must be replaced as
soon as possible to avoid losing the parameter settings.
Please contact Roland service or your dealer.
Patches do not change when a
program change is received from an
external device
❍ The program change message may have been
transmitted on a channel different from the MIDI
channel that’s been specified through the “MIDI
Channel” parameter of the System MIDI screen.
➝ Transmit the program change message on the MIDI
channel that is specified by the “MIDI Channel” setting.
❍ An invalid bank select message may have been
transmitted.
➝ Transmit a bank number MSB that the V-Bass is able to
use.
Cannot transmit or receive data via
bulk dump
❍ Are you performing the operation in the Bulk Dump
reception/transmission screen?
➝ Move to the Bulk Dump transmission/reception screen.
❍ Is the MIDI sequencer you are using able to record
exclusive messages?
➝ Use a MIDI sequencer that is able to record exclusive
messages. We recommend the Roland MC-80.
❍ When receiving data, have you specified the device ID
number that was used when the data was transmitted?
➝ Specify the same device ID number as was used when
transmitting the data.
Reset to Default Factory
Settings (Factory Reset)
You can restore (initialize) the V-Bass to the factory-set
condition. This is called “Factory Reset.”
You can initialize all settings, or just a specified range of
data, such as patches in the user area or system settings.
The following data can be initialized.
fig.6-01
1. Turn off the power.
2. Hold down [PAGE ] and [PAGE ], and turn on
the power.
A screen in which you can specify the range of data to be
initialized appears.
fig.6-02
3. Use [CURSOR] to move the cursor to “START,” and
use the VALUE dial to specify the starting point of the
data to be initialized.
4. Use [CURSOR] to move the cursor to “END,” and use
the VALUE dial to specify the end point of the data to
be initialized.
5. Press [WRITE].
The display will ask “ARE YOU SURE?”
6. To initialize the data, press [WRITE].
The specified range of data will be initialized, and then
the V-Bass will enter the normal power-on state.
* If you decide not to proceed with the initialization, press
[EXIT]. The initialization will be cancelled, and the V-Bass
will enter the normal power-up state.
