Archiving the Console Settings
The console settings can be saved to an external
device such as a MIDI sequencer or data archiver
using the dump out facility. Settings can be loaded
back into the console using dump in. This is ideal
when you want to archive the settings to use at a
later date, for example a re-run of a previous
performance. You can also use the dump facility to
program additional
ML3000
consoles, for example
when setting up duplicate shows or swapping
consoles around. Simply link MIDI OUT from one to
MIDI IN of the other and action the dump out facility.

MIDI Dump Out
Connect the console to a suitable MIDI archiving
device. Set the same MIDI channel number on
both. Check the rear switch is set to MIDI. Press
the MIDI and VIEW keys together. The console
dumps the current settings and memory contents
using a SysEx message string. During this time
the
MIDI LED lights to show that data is being sent via
the MIDI port. Note that this operation can take up
to 10 seconds during which time the console mutes
and assignment operations are interrupted.
MIDI Dump In
Connect the console to the MIDI archiving device.
Set the same MIDI channel number on both. Check
the rear switch is set to MIDI. Start the process
using the MIDI archiver. The console current
settings and memory contents are overwritten.
During this time the MIDI LED lights to show that
data is being received by the console. Note that this
operation can take a while during which time the
console mute and assignment operations are
interrupted.
If you are using a MIDI sequencer to record the
dump out data string then make sure you play it
back at the same speed you recorded it. If you
dump it back into the console faster than it was
recorded some data may not load correctly.
MIDI Dump Message Format
The format for dump out and in is identical. The
dump data string is made up of multiple System
Exclusive messages (known as packets) which
contain the console information.
Transmit and Receive
. The format for a single
packet is as follows:
F0 <SysEx header> <packet type> <packet
number> <data> <checksum> F7
<SysEx header> = 00 00 1A 50 07 VV vv nn
Where VV = software version number – major
vv = software version number – minor
nn = console MIDI channel number
<packet no.> = packet number from 0 to 127
<data> = block of console data (7-bit format)
<checksum> = checksum to allow error detection
MIDI Dump Errors
If the console or connected equipment fails to
respond to a MIDI dump then check:
•
The MIDI cable is good and correctly plugged
•
The correct MIDI channel number is selected
•
The console rear panel switch is set to MIDI
•

Allen & Heath ML Archiver
The ML Archiver Windows™ utility for the PC can
be downloaded from the Allen & Heath Internet site.
This can be used to archive data to and from the
PC via MIDI or RS232.
The program also includes the useful Snapshot
Manager which lets you store and recall the console
mute settings and VCA group assignments from the
128 internal snapshot memories. The snapshots
cannot be accessed from the console control panel
itself. The archiver provides this extra feature.
Check the Allen & Heath Web site for further details
and loading instructions.
