Roland GR-20 Workshop Guide


Reloading the GR-0’s Memory from a Bulk Dump
Making sure that the external MIDI device’s MIDI OUT is connected to
the MIDI IN of the GR-20, power down the GR-20.
While holding down the GR-20’s PATCH EDIT button, turn
on the GR-20—the GR-20 powers up with “dP,” for “dump,”
on the display.
Turn the Number/Value dial so the GR-20 display reads
“Ld,” for “Load.”
Send out the SysEx data from the MIDI device—as the
GR-20 receives the data, its display shows “r..”
When “Ld” returns to the display, press the GR-20’s WRITE button to
store the received SysEx data.
Power down the GR-20, and then turn it on again to return to normal
operation.
