Korg CX-3 Manual: Understanding Video Timing Parameters and Data Dumps

Appendices

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.

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

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.

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.
