Is the appropriate “Rx” parameter active? If not, switch it on.
After connecting the BK-7m’s COMPUTER port to
your computer, the BK-7m doesn’t receive MIDI
messages.
The BK-7m may be receiving on a MIDI channel on which the MIDI
controller doesn’t transmit. Correct the MIDI controller’s transmit
channel or use the BK-7m’s wizard.
22
Unable to read from/write to USB memory. Are you using an (optional) Roland USB memory (M-UF series)?
Reliable performance cannot be guaranteed if you use non-
Roland USB memory products.
Check the format of your USB memory. The BK-7m can use USB
memory that has been formatted as FAT. If your USB memory was
formatted using any other method, please re-format it using the
BK-7m.

Can’t save to USB memory. Could the USB memory be write protected?
Is there sufficient free space on the USB memory?
Audio recording won’t start or stops unexpectedly. Are you using an (optional) Roland USB memory (M-UF-series)?
Reliable performance cannot be guaranteed if you use non-
Roland USB memory products.
Is there sufficient free space on the USB memory?
The external screen remains dark. Did you connect it to the VIDEO OUTPUT socket? 17
Did you switch on your TV or external screen—and did you select
the correct channel? See the TV’s or screen’s owners manual for
how to select the channel that corresponds to the video input to
which the BK-7m is connected.
Are you using a supported TV or monitor screen?
Thin horizontal lines flicker in the television
screen.
Thin horizontal lines may flicker on the television screen, but this
is due to the television itself, and is not a malfunction of the
BK-7m.
Can’t see the edge of the image on the television
screen
In some cases, the edge of the image may not be visible on the
television screen, but this is due to the characteristics of the tele-
vision and is not a malfunction on the BK-7m.
Lyric display is wrong. For some types of music files, the lyrics may sometimes be dis-
played incorrectly. Some words may be incorrectly shown outside
the screen display area.
Insufficient volume from a device connected to
the BK-7m’s AUDIO INPUT sockets.
Could you be using a connection cable that contains a built-in
resistor? Use a connection cable that does not contain a resistor.
Check the setting of the AUDIO IN knob and correct it, if neces-
sary.
The songs won’t play. The file type of the song is not one of the file types that the
BK-7m can play.
35
It may be that the song data is damaged.
No Performance Lists are displayed. The USB memory doesn’t contain any Performance List files.
For some reason the USB memory is not recognized.
