The DJ-70 comes equipped with 2Mb of sampling memory which allows 45 seconds of sampling time at 44.1 kHz (90 seconds at 22.05 kHz). You can expand the memory to a total of 4Mb which increases the available Sample time to 45.3 seconds at 44.1 kHz (90 seconds at 22.05 kHz). The DJ-70 uses standard SIMMs memory, similar to that used in computers.

The DJ-70MkII also comes equipped with 2Mb of sampling memory which allows 45 seconds of sampling time at 44.1 kHz (90 seconds at 22.05 kHz). You can expand the memory to a total of 32Mb which increases the available Sample time to 6 minutes at 44.1 kHz (12 minutes at 22.05 kHz). The DJ-70mkII uses standard 8 or 16Mb SIMMs, similar to that used in computers.

This procedure requires that you open the case of the DJ-70/DJ-70MKII. If you feel uncomfortable with this operation, you should have a Roland registered technician install the memory for you. For information on Roland service technicians and compatible SIMMs, refer to page 4 (SCSI Interface).

Use the following steps to install memory into the DJ-70 or DJ-70mkII:

NOTE: Always use proper anti-static precautions before handling SIMMs modules. If possible, use an anti-static wrist strap for this procedure. If one is not available, make sure you touch a grounded metallic case before handling the SIMMs modules.


1. Turn off the DJ-70/DJ-70mkII's power switch and unplug the power cord.
2. Remove the screws that hold the upper case to the chassis. There are eight Phillips head screws that surround the base of the unit. Be sure to place the screws in a safe place, as you will need them to reassemble the case.
3. Remove the screws that hold the cover. Be careful not to pull out the cables connected to the printed circuits.
4. Open the case and detach the keyboard assembly that is mounted to the chassis. You should now be able to see the two empty SIMMs slots. You can lean the cover against the rear of the instrument without disconnecting the cables.
5. Hold the SIMMs modules by the edges, gently place them into the empty slots, and push them back against the two plastic clips until they snap into place.
6. Reassemble the case and power up the DJ-70/DJ-70mkII. During the bootup procedure, the "Wave Memory Check" display should indicate the increase in available Sample time.
NOTE: On the DJ-70MKII, SIMMs socket #1 will except either 8 or 16Mb SIMMs whereas socket #2 will only accept 16Mb SIMMs. Also, when you expand the DJ-70mkII's memory to 32Mb the original 2Mb that came with the instrument are no longer used.
