Local Control On setting
If you make connections as shown on the preceding page,
you must turn on the Echo Back setting of the external
MIDI sequencer or computer (so that the data it receives
at MIDI IN will be retransmitted without change from
MIDI OUT), and turn off the Local Control setting of the
BX-3 (to disconnect the keyboard section from the tone
generator section).
When you play the keyboard of the BX-3, the data will be
sent to the external MIDI sequencer or computer, and will
be echoed back to sound the tone generator of the BX-3.
In other words by turning the BX-3’s Local Control off,
you can prevent notes from being sounded in duplicate;
once from the keyboard and again from the echo-back.
To turn off Local Control, set the Global mode Group 4
“MIDI Local Cntrl” parameter to Off.
If you are using the BX-3 by itself, you must turn Local
Control on. (If this is off, playing the BX-3’s keyboard will
produce no sound.)
Connecting a MIDI keyboard
If you want to connect a MIDI keyboard to the BX-3's
MIDI IN connector and use the BX-3 as a sound module,
you will need to set the following parameters.
Set the Global mode Group 2 “MIDI Upper Rx ch” and
“MIDI Lower Rx ch” parameters to match the MIDI
channel of your connected MIDI device.
If you want to transmit program changes from the
connected MIDI device or to control the panel keys of the
BX-3, set the Global mode Group 2 “MIDI Global ch”
parameter to match the transmit channel of the connected
MIDI device. MIDI control change numbers can be set in
Group 4 and 5.
If you are recording your BX-3 performance on a se-
quencer, and want the state of all panel keys to be repro-
duced, use the following procedure.
Since Drawbar 1, 2, and DRAWBAR SELECT are not
reproduced by program changes, use DRAWBAR SE-
LECT to select the drawbars that you will use first in your
performance. Then execute Global mode Group 7 “Draw-
bar Scan” to transmit the state of Drawbar 1 and 2.
Immediately when you begin recording, transmit a
program change by selecting the program that you will
use for your performance. Now the sequence will contain
the data needed to reproduce the settings for each live set
of drawbars.
When using a velocity-sensitive MIDI sound module
With the factory settings, the BX-3 is set to transmit note
messages with a fixed velocity.
If you are using a velocity-sensitive MIDI sound module,
you will need to set the following parameters.
Set the Global mode Group 2 “MIDI Upper 2nd ch” and
“MIDI Lower 2nd ch” parameters to other than Off. This
will cause note messages with velocity to be transmitted
on the specified MIDI channel.
However in this state, two sets of note messages (one
with variable velocity, and another with fixed velocity)
will be transmitted, so you should also set the Global
mode Group 2 “MIDI Upper Tx ch” and “MIDI Lower Tx
ch” parameters to Off, so that the fixed-velocity note
messages will not be transmitted.
Alternatively, you could set “MIDI Upper 2nd ch” and
“MIDI Upper Tx ch,” and “MIDI Lower 2nd Tx Ch” and
“MIDI Lower Tx Ch,” to different channels so that they
do not conflict, and then make settings on the connected
MIDI sound module so that it receives the note messages
with variable velocity.
If Global mode Group 1 “Key Trigger” is set to
Shallow, the note message with fixed velocity will be
transmitted when you have only pressed the key
lightly. However, the note message with variable
velocity will not be transmitted until you have
pressed the key all the way. This means that if you
have made settings to transmit note messages with
variable velocity, it is possible for the BX-3 to
produce sound without a note message being
transmitted. In order to match the timing at which
the BX-3 sounds with the timing at which your MIDI
sound module will sound, set the “Key Trigger”
parameter to Deep.
MIDI data dump
Exclusive data (internal settings) can be transmitted from
the BX-3 to a connected MIDI data filer or another BX-3.
Transmission
While data is being transmitted, do not touch the
keys, drawbars, or knobs of the BX-3. Also, never
turn off the power of the BX-3 while data is being
transmitted.
The following four types of data dump can be transmit-
ted.
Dump one program
Dump all programs
Dump global data
Dump all data (programs and global data)
To transmit a data dump
1. Connect the MIDI OUT connector of the BX-3 to
the MIDI IN connector of the device that will
receive the data dump.
2. Enter Global mode.
The key LED will light.
3. Press the PROGRAM [7] key, and then press the
[®] key twice.
The display will indicate Dump.
4. Press the [WRITE/ENTER] key.
The display will indicate Dump Program, and
“Program” will blink.
5. Select the data that you want to dump.
If you want to dump one program, press the [®] key
once, and then use the [-][+] keys to select the pro-
gram.
The programs that will be dumped will be the pro-
grams contained in the mode that was selected before
