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
