●MIDI Merge Settings

If you want MIDI signals received by the BBT500’s MIDI IN jack transmit-
ted without alteration to other MIDI devices connected to the BBT500’s
MIDI OUT jack, set the MIDI Merge to “on”, if not, set it to “oFF”.
1
Press and hold the [FUNCTION] switch for more than three sec-
onds (until “utL” appears on the display) to enter the Utility Mode.
2While holding the [MANUAL] switch, press Memory Switch [4].
The current MIDI Merge setting appears on the display (after a
few seconds the display will return to “utL”).
3Use Memory Switches [1] and [2] to set MIDI Merge either “on”
(Memory Switch [2]) or “oFF” (Memory Switch [1]).
4Press the [FUNCTION] switch to enter the Amp Mode.

●MIDI Bulk Out

You can use the MIDI Bulk Out operation to back up data saved in the
BBT500 (data in memory 1-5 and Utility Mode settings) to a device that
can save MIDI data (such as a Yamaha MDF3, etc.).
1Using a MIDI cable, connect the MIDI OUT jack on the BBT500
to the MIDI IN jack on an external MIDI device.
*Use only a standard MIDI cable that is less than 15 meters in length. Use
of a longer cable can result in trouble such as abnormal operation, etc.
2Hold the [FUNCTION] switch for more than three seconds (un-
til “utL” appears on the display) to enter the Utility Mode.
3While holding the [MANUAL] switch, press Memory Switch [5].
The type of data to be sent with the Bulk Out operation ap-
pears on the display (after a few seconds the display will re-
turn to “utL”).

4Use Memory Switches [1] and [2] to set the type of data (1-5,
ALL) to be sent with the Bulk Out operation.
1-5 ...... Sends only the data from the selected memory number.
ALL ..... Sends all data in memory numbers 1-5 and Utility Mode
settings.
5Press Memory Switch [5] to carry out the Bulk Out operation.
While the Bulk Out operation is in progress, all lamps on the
unit will light.
*The device number becomes the MIDI receive channel number (→ pg.
16). When the MIDI receive channel is set to “ALL” (Omni ON), the
channel is set to 1.
6Press the [FUNCTION] switch to enter the Amp Mode.

●About MIDI Control Changes

You can control the overall volume of the BBT500 by connect-
ing an external MIDI device’s MIDI OUT jack to the BBT500’s
MIDI IN jack, and transmit Number 7 Control Change Mes-
sages (Main Volume) to the BBT500.
*With the exception of the Number 7 Control Change, the BBT500
does not recognize any other MIDI Control Change messages.
*The Main Volume data will not change, even if a different memory
number is selected.
*When the POWER is switched ON, the Main Volume data is set
to its MAX value.
*
After the Main Volume data is changed, and the external MIDI device
is disconnected, the pre-amp’s volume level may not be sufficient. If
this case occurs, transmit a Control Change with a higher volume
setting again, or switch the POWER OFF and then back ON.

●About MIDI Bulk In

Using a MIDI cable, connect the MIDI IN jack on the BBT500 to
the MIDI OUT jack on an external MIDI device to return data
that has been stored on the external device, to the BBT500’s
memory. This operation is referred to as MIDI Bulk In.
*The device number becomes the MIDI receive channel number
(→ pg. 15). When the MIDI receive channel is set to “ALL” (Omni
ON), the channel is set to 1. When set to “oFF” (OFF) data will
not be received.
*“Ld” appears on the display while receiving MIDI Bulk data.

●Sending/Receiving MIDI Data Between

Two BBT500s

The MIDI Bulk In or MIDI Bulk Out operations can be used to
copy memory or Utility Setup data in one BBT500 to another
BBT500.

●Restoring the Factory Presets

This operation clears the contents
of the BBT500’s memory 1-5 and
restores all parameters to their
factory preset settings.
While holding the [MANUAL]
switch and Memory Switch [5],
switch the POWER switch ON.
