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. Saved 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

ML5000 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.

Settings which are archived :

9

Current mute settings

9

Current Mute group assignments

9

Current VCA group assignments

9

Automation safes

9

Solo-in-Place safes

9

All snapshot memories

Settings which are not archived :

8

Current console operating mode

8

Current PAFL selection and settings

8

Store and auto-increment on/off

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. Hold
down SHIFT M9 and press STORE M4 . The
console dumps the current settings and memory
contents using a SysEx message string. During this
time

dPo is displayed. Note that this operation

can take up to 10 seconds during which time the
console mutes, assignment, SIP and P/AFL
operations will be 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

dPI is displayed. Note that this

operation can take a while during which time the
console mute, assignment, SIP and PAFL
operations will be 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 number> F7

= 00 00 1A 50 07 VV vv nn

Where VV = software version number – unit

vv = software version number – decimal

nn = console MIDI channel number

= packet number from 0 to 127

= block of console data (7-bit format)

= 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 same MIDI channel number is selected

The rear panel switch is set to MIDI

• Try

again

If a data error is detected during a dump out or in
the console display will show an error message
code:

Er1 Buffer

overflow

Er2

Packet out of sequence / missing

Er3

Checksum error / corrupt data

Er4

Invalid packet length

Er5 Input

timeout

Er6

Unsupported block type

Er7

Invalid scene number

Er8
