MIDI Dump Data
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, snapshots,
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 GL4800 consoles,
for example when setting up duplicate shows or swapping consoles
around.
MIDI Dump Out
Press SHIFT + STORE
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 snapshot system is
locked out. However, the channel mutes may be operated in the
normal way so that live operation may continue unaffected.
MIDI Dump In
The console responds automatically to the System Exclusive dump in
message formatted as above.
While the console is receiving dump in data the display flashes dPI
(around 15 seconds).
While dump is in progress the mute group and snapshot system is
locked out. However, the channel mutes may be operated in the
normal way so that live operation may continue unaffected.
On completion the console restores normal operation with the new
memory settings in place.
Dump Errors
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 explanation of these.
