5. When transmission is finished, the display will
indicate RxSysEx Completed.
If the display indicates RxSysEx Error, turn the power
off. Then while holding down the Program [2] and [7]
keys, turn the power on again. However, this will
initialize the contents of memory.
When the CX-3 receives data for one program, it will
enter the same mode (Normal mode or EX mode) in
which it was when that program was transmitted.
Since the CX-3 will switch to the received mode, you
will be in that mode when you press the [GLOBAL]
key or [EXIT] key to exit Global mode after receiving
the data dump.
MIDI messages that the CX-3
transmits and receives
[...] indicates hexadecimal notation
MIDI channels
MIDI messages can be received if the MIDI channels
of the transmitting and receiving devices match. There
are sixteen MIDI channels; 1–16.
MIDI messages are transmitted and received on the
global MIDI channel. The global MIDI channel is the
basic channel for MIDI transmission and reception,
and is set by the Global mode Group 2 “MIDI Global
Ch” parameter.
Note-on/off
Note-on [9n, kk, vv]
Note-off [8n, kk, vv]
(n: channel, kk: note number, vv: velocity)
Each time you press or release a note on its keyboard,
the CX-3 will transmit a note-on or note-off message.
Very few devices transmit note-off velocity, and the
CX-3 does not transmit note-off velocity either.
Program change / Bank select
Changing the program / bank
Program change [Cn, pp]
(n: channel, pp: program number that selects from up
to 128 sounds)
• Programs 000–127 in banks A–H correspond to
program changes [Cn, 00]–[Cn, 7F].
Bank select MSB (CC#...) [Bn, 00, mm],
Bank select LSB (CC#...) [Bn, 20, bb]
(n: channel, mm: upper byte of bank number, bb:
lower byte of bank number)
The program or bank will not change immediately
when a bank select message is received. The program
and bank will change only when a program change
message is subsequently received.
5. If you wish to execute the dump, press the
[WRITE/ENTER] key.
To cancel the dump, press the [EXIT] key.
While the data is being transmitted, the display will
indicate TxSysEx Processing...
The following table shows the size of each data dump
and the time it will require.
Data type Data size Time required
1 Program Parameter 153 Byte 1 second
All Programs Parameter 18.3 kByte 12 seconds
Global Parameter 300 Byte 1 second
All Prog+Global Parameter
18.6 kByte 12 seconds
If you save data dumps on a MIDI data filer, do not
save multiple dumps together. If you save multiple
dumps together, the CX-3 will not have enough time
to write the data into memory after receiving it (see
the section that follows), and the data will not all be
received.
Reception
While data is being received, do not touch the CX-3’s
keys, drawbars, or knobs, and never turn off the power.
When a data dump is received, the CX-3’s display
will indicate RxSysEx Processing... While this is
displayed, you must never turn off the power of the
CX-3. If you turn off the power, the CX-3 may not
function correctly the next time it is turned on again.
If this occurs, hold down the Program [2] and [7]
keys and turn on the power. However, this will
initialize the contents of memory.
While data is being written into memory, MIDI
transmission and reception will not occur. If you
want the CX-3 to receive multiple data dumps in
succession, you must allow a sufficient interval
between the transmitted data dumps.
Data type Writing time
1 Program approx. 1 second
All Programs approx. 7 seconds
Global Parameter approx. 1 second
All Prog+Global Parameter approx. 7 seconds
Receiving a data dump
1. Connect the MIDI IN connector of the CX-3 to the
MIDI OUT connector of the device that will trans-
mit the data dump.
2. Set the Global channel of the MIDI device to match
the global MIDI channel of the CX-3 (set by the
Global mode Group 2 “MIDI Global Ch” parameter).
If data that was previously transmitted to a MIDI
device is being re-transmitted back to the CX-3, set the
global MIDI channel of the CX-3 to the setting that
was used when transmitting the data.
For details on setting the MIDI channel for transmission,
refer to the owner’s manual of the device you are using.
3. Set the Global mode Group 4 “MIDI Rx Sys Exc”
parameter to Ena.
4. Send the data dump from the transmitting device.
Refer to the owner’s manual for your device and
transmit the data.
If the “MIDI Rx Sys Exc” parameter is set to Ena,
data dumps can be received in either Normal mode
or EX mode.
