About synchronization in Song mode

In Song mode, the ESX-1 will also transmit Song Select and Song Position Pointer messages.

Song Select

When you switch songs, a Song Select message [F3, ss] (ss: song number) will be transmitted. On the ESX-1 you can select 64 songs. If the ESX-1 receives a Song Select message when in Song mode, it will switch songs.

You can use the Global mode MIDI Filter settings to enable/disable transmission and reception of Song Select messages.

Song Position Pointer

If you change the song position of the master device (clock set to “Int”) while the song is stopped, it will transmit a Song Position Pointer message [F2, pp, pp] (pp, pp: lower and upper bytes of the value;

pp:the number of MIDI beats from the beginning (number of timing clocks / 6)).

The Song Position Pointer message indicates the location at which the sequencer is currently stopped. If the slave (clock set to “Ext” or “Auto”) receives a Song Position Pointer message in Song mode, it will change its own current location (i.e., the location at which its currently selected song is stopped) to the same location as the master.

On the ESX-1 however, the length will differ for each pattern, so the master and slave will not nec- essary be located at the same position.

If you change the position on the master device to make it transmit a Song Position Pointer message, and then press its START/PAUSE key, a Continue message (or a Start message if the position is 001) will be transmitted, and the song will begin play- ing.

If a slave receives a Continue message, it will be- gin playback (in synchronization to the incoming Timing Clock) from the position indicated by the Song Position Pointer message it received. This lets you playback in synchronization from the desired location in the song, just as when playing back in synchronization from the beginning.

Song Position Pointer messages are not transmitted when you use the dial or the select keys to fast- forward or rewind during playback.

Be aware that if you perform such operations during synchronized playback, synchronization will be lost. Also, the playback location will not change if a Song Position Pointer message is received during playback.

Editing sounds

By using MIDI exclusive data dumps you can edit all patterns or one pattern at a time. You can also use NRPN messages to edit the knobs that are valid for each part.

Editing via NRPN

NRPN (Non-Registered Parameter Number) messages are a type of message that can be freely used by any manufacturer to control the assigned parameter number. On the ESX- 1, you can use control change messages to edit keyboard part parameters or effect section parameters, but NRPN messages are assigned to the drum parts.

To edit a drum part parameter, use NRPN (LSB) [Bn, 62, rr] and NRPN (MSB) [Bn, 63, mm] (control change #98 and 99) (rr, mm: lower and upper bytes of the parameter number) to select the desired parameter. Then use data entry (MSB) [Bn, 06, mm] and data entry (LSB) [Bn, 26, vv] (control change #6 and 38) (mm, vv: upper and lower bytes of the value, together expressing a range of 16,384 steps) to set the value.

About system exclusive messages

Since the way in which system exclusive messages are used is left completely up to the manufacturer, these messages are used mainly to transmit or receive sound parameters or editing data that is specific to a particular device. The ESX-1’s system exclusive message format is [F0, 42, 3n, 71, ff, ... F7].

F0: exclusive status

42: Korg ID

3n: [n=0~F] global MIDI channel 1~16

71: the ESX-1’s model ID

ff:function ID (type of message)

...

F7: end of exclusive

Some USB-MIDI interfaces are unable to transmit or receive the ESX-1’s MIDI exclusive messages.

Universal system exclusive messages

There is a special category of system exclusive message whose uses are publicly defined. These are called Universal System Exclusive messages.

The ESX-1 implements the following Universal System Exclusive messages.

—Inquiry Message Request [F0, 7E, nn, 06, 01, F7] —Inquiry Message [F7, 7E, nn, 06, 02, (9 bytes), F7] When the ESX-1 receives an Inquiry Message Re- quest, it will respond by transmitting an Inquiry Message with the meaning of ‘I am a Korg ESX-1 with system version ...’

If you wish to obtain the “MIDI Implementation” which includes information on the MIDI Exclusive format, please contact Korg distributor.
