The Scene Memory function

In Utility mode you can make various settings related 
to scene memory and MIDI. In this mode you can 
also transmit a bulk dump to backup the entire con-
tents of scene memory on your sequencer or com-
puter.

1. From Normal mode, press the 

UTILITY switch in the control sec-
tion and immediately release it. (If 
you press and hold the UTILITY 
switch for one second or more, 
you will exit Utility mode and 
return to Normal mode.)

The indicator above the UTILITY switch will light, 
and you will enter Utility mode. At this time, the 
MEMORY display will alternately indicate the cur-
rently selected utility item and its value.

2. Repeatedly press the UTILITY 

switch so that the desired item 
appears in the MEMORY display.

3. Use the

 switches to modify 

the value of the selected item.

section “Utility items.” For some 
items, other switches are also used to 
execute the function.

4. To exit Utility mode, press and 

hold the UTILITY switch for one 
second or longer. The M2500 will 
return to Normal mode.

The items that can be selected in Utility mode and

of the following displays appears, please contact your 
dealer to have the battery replaced or service per-
formed.

This is a function that prevents important scene 
memories from being erased accidentally. If this is on 
(on), it will not be possible to store scenes. Also, the 
contents of scene memory will not be rewritten even 
if a bulk dump is received from the MIDI IN connec-
tor.

Specify the function of the DIRECT RECALL 1–8 
switches.

• If “

” is selected

These switches will function as direct recall switches 
to directly recall scene memory numbers 1–8.

• If “

” is selected

These switches will function as mute group switches 
to add/cancel mute groups 1–8. (For details on mute 
groups, refer to page 37.)

This function erases scene memories. Specify the 
value and press the STORE key to erase the scene 
memory.

• If “

” is selected

All scene memories (1–128) will be erased.

• If “ ”–“

” is selected

The scene memory of the corresponding number (1–
128) will be erased.

Note: If the “

” (bulk dump request) item is dis-

played, pressing the UTILITY switch once again 
will return you to Normal mode.

Note: If a MIDI program change is received while 
in Utility mode, the M2500 will return to Normal 
mode.

• It is not possible to recover a scene memory 

that has been erased.

• If the “

” (memory protect) item is on, the 

memory initialize function cannot be executed.
