THE INTERNAL AND CARTRIDGE MEMORIES

We have already described how to play voices that are

stored

in the internal memories or cartridge

memories.

As part of the tutorial, we have also described how to

store a single voice. The following instructions provide

additional detail on the use of these memories for

storing and rearranging voices. To remain consistent

with the panel labels on the DX7, we use the term

"Store" to describe the process of placing the currently

selected voice (the one which is being played or edited)

into any location (1-32) in the internal or cartridge mem-

ories. We use the term "Save" to describe the process of

simultaneously placing all 32 internal memory voices

into the correspondingly numbered cartridge memories.

We use the term "Load" to describe the process of trans-

ferring the 32 voices from one bank of a ROM cartridge,

or from a RAM cartridge, into the 32 internal memories.

Memory Protect

When you store a voice (or voices) into an internal or

cartridge memory, whatever voice had been in that

memory location is automatically erased... just like

recording new material over an old tape (although

recording tape is not involved). To help you avoid the

frustration and inconvenience of accidentally erasing

any voices, the DX7 is equipped with several types of

Memory Protection. The [MEMORY PROTECT] but-

tons provide independent "software" protection for the

internal and cartridge memories. In addition, the RAM

cartridges themselves have "hardware" memory protect

switches. You can always "read" or "load" a voice from a

memory regardless of memory protect status. However,

you cannot store a voice in any internal memory (or

load the RAM voices into the internal memories) unless

the internal memory protect is first disabled (turned

OFF). Similarly, you cannot store a voice in any internal

memory (or save the 32 internal voices to RAM car-

tridge) unless the cartridge's hardware memory protect

switch is OFF and the DX7's software memory protect-

cartridge feature is also OFF

The following instructions describe the procedure for

turning the memory protect off; they also instruct you to

turn ON the memory protect as soon as the voice(s)

have been stored. It is a good idea to always turn ON

the memory protect unless you specifically need to store

a voice. This habit may someday avoid accidental era-

sure of your voices.

Storing individual voices to

RAM

cartridge

1. First make sure the Memory Protect switch on the

RAM cartridge is turned OFF (switch positioned away

from the connector).

2. Whether you have been playing an internal voice,

editing a voice, or creating one from scratch in the

VOICE INIT mode, turn off the software memory pro-

tect. Press [MEMORY PROTECT-CARTR1DGE],

and the display will indicate "MEMORY PROTECT

CARTRIDGE ???". If "???" is "OFF", the software pro-

tection is already off and you can go directly to Step 3.

If the"???" is "ON", then press the [OFF] button.

3. Press the [MEMORY SELECT-CARTRIDGE] but-

ton, and then press the [STORE] button and hold it

down while pressing the voice selector button (1-32)

which corresponds to the RAM cartridge memory in

which you wish to store the voice. The LCD display

will briefly indicate "Under Writing", and will then

return to the voice name and number, indicating the

voice has been stored.

NOTE:

If you attempt this step with either the software

or hardware cartridge memory protection ON, the dis-

play will indicate "MEMORY PROTECTED" as soon

as you press

[STORE].

If, when you release

[STORE],

the voice name reappears, then the soft-

ware memory protect is ON; perform Step 2 as above,

then Step 3 again. If, when you release

[STORE],

the

"MEMORY PROTECTED" message remains dis-

played, the hardware protect is ON; perform Step 1,

then Step 3 again.

4. Once the voice is stored, press [MEMORY PRO-

TECT- CARTRIDGE] and [YES] to reactivate the

software memory protection, and then reset the

switch on the RAM cartridge to reactivate its hardware

memory protection.

Saving all 32 internal memory voices

to

RAM

cartridge

1. First make sure the Memory Protect switch on the

cartridge is turned OFF (switch positioned away from

the connector). Then turn off the software memory

protect by pressing [MEMORY PROTECT-CAR-

TRIDGE] followed by [OFF].

2. Press [FUNCTION] to place the DX7 in FUNCTION

mode, and then press [SAVE]. When the display asks

"SAVE MEMORY ALL OF MEMORY?", press [YES]

(unless you change your mind, in which case you

should press [NO] and go on to whatever function

you wish).

3. Because you are about to erase whatever voices are in

the RAM cartridge, the DX7 gives you one more

opportunity to change your mind by asking "SAVE

MEMORY, ARE YOU SURE?" If you indeed want to

save the 32 internal voices in the RAM cartridge,

press

[YES]

this second time (if not, press

[NO])

.

4. The display will indicate "SAVE MEMORY, UNDER

WRITING!" for stout 20 seconds as the voices are

being written (saved) onto the cartridge. The d i s p l a y

will then indicated "SAVE MEMORY COMPLETED", at

which point you can select whatever mode you wish

5. Once the 32 voices are saved, press [MEMORY

PROTECT- CARTRIDGE] and [YES] to reactivate

the software memory protection, and then reset the

switch on the RAM cartridge to reactivate its hardware

memory protection.

Loading

all

32

ROM

or

RAM

cartridge

voices to internal memory

1. First turn off the internal memory protect. Press

[MEMORY PROTECT-INTERNAL], and the dis-

play will indicate "MEMORY PROTECT INTERNAL

???". If "???" is "OFF", the internal memory protection

is already off and you can go directly to Step 2. If the

"???" is "ON", then press the [OFF] button.

2. Press [FUNCTION] to place the DX7 in FUNCTION

mode, and then press [LOAD]. When the display

asks "LOAD MEMORY ALL OF MEMORY?", press

[YES] (unless you change your mind, in which case

you should press [NO] and go on to whatever func-

tion you wish). Because you are about to erase what-

ever 32 voices are in the internal memory, the DX7

gives you one more opportunity to change your mind

by asking "LOAD MEMORY, ARE YOU SURE?" If you

indeed want to load the 32 RAM voices into the inter-

nal memory press [YES] this second time (if not,

press [NO]). After a second or so, the message "LOAD

MEMORY COMPLETED" appears, telling you the

voices are loaded.

3. Once the 32 voices are loaded, press [MEMORY

PROTECT- INTERNAL] and [YES] to reactivate

the internal memory protection.

Transfering a single voice from one

location to another in the

RAM

cartridge or internal memory

You may wish to rearrange the voices so they fall in a

particular order as, for example, when you are going to
