When a MIDI DUMP OUT is performed the entire contents
of the console memory is transmitted down the selected
MIDI channel. This includes the current console mute
settings, mute groups, patches, safe settings, solo settings,
console modes, and console MIDI channel number. When
a MIDI DUMP IN is received the console memory is
completely overwritten.
This is ideal when you want to archive settings and recall
them at a later date, for example a re-run of a previous
performance. You can also use the dump facility to program
additional GL4000 consoles, for example when setting up
duplicate shows or swapping consoles around.

The dump is started down the selected console MIDI
channel. If MIDI has been disabled (channel = OFF)
then nothing will happen when dump is activated.
The display flashes dPo during the duration of the
dump (around 15 seconds).
While dump is in progress the mute group and patch
system is locked out. However, the channel mutes
may be operated in the normal way so that live
operation may continue unaffected.

If the console or connected equipment fails to respond to a MIDI
dump then check that the MIDI is correctly enabled on each. Check
that the cables are correctly plugged. In the event of a data error
being detected during a MIDI dump out or in the display will show
an error message code. Refer to the section on TECHNICAL
SUPPORT for an explaination of these.
