Introduction
The
facility
now
exists
to
view
the
output
levels
and
status
modes
of
MX
`at
a
glance'
either directly
via
an
ANSI
terminal
available
from
Strand
Lighting,
or
alternatively
a
Terminal
Emulator
program
is
available
for
any
PC
compatible,
running
any
level
of
DOS,
with
the
option
to
view
in
colour

version
is
a

and
involves
no
input
from
the
PC
keyboard
other than
booting
up
and
exiting
.
The

MIDI
APPLICATIONS
Introduction
The
main
purpose
of
incorporating
MIDI
into
Strands
lighting
desks
is
to
create
an
interface
between
light
and
sound
.
MIDI
is
now
an
industry
standard,
in
much
the
same
way
that
SMPTE
is
for
the
film
industry,
and
all
faders
and
switches
on
MX
are
allocated
unique
MIDI
codes
for
use
with
this
interface
.
MIDI
transmits
and
receives
over 16
channels
.
These
are
dedicated
MDI
channels
and
have
nothing
in
common
with
any
light
channels
.
All
MIDI
devices
generally
default
to
Channel
1
including
MX
.
Each
MIDI-equipped
instrument
usually
contains
a
receiver,
a
transmitter,
and
an
optional
socket
providing
a
through
(THRU)
facility
for
relaying
information
to
other
Midi
devices
.
MX
contains
these three
ports
.
The
THRU
socket
is
a duplicate
of
the
signals
on
the
IN
socket
therefore
allowing
information
from
a
-master
unit to
be
relayed-to-another
MIDI
unit
. -
A
-
fine is
normally
drawn
signifying
this
as
shown
in
the figure
below
.

n
MostMidi
sequencers
are
software
orientated
and
run
on
a
variety
of
personal
computers,
the
most
popular being
the
Atari,
Mac
.
and
more
recently
the
P
C
.
At
present
only
the
Atari
has
built
in
Midi
Sockets,
hence
to
date
this
has
been
the
most
popular
computer
for
Midi
applications,
others require
separate
interfaces
to
be
purchased

EXAMPLE
1-
The
purpose
of
this
exercise
is
to
make
lighting
changes
occur
automatically
in
harmony
with
a
musical
sequence
.
The
figure
below
shows
a
typical
setup
ready
for
recording
utilising
sequencer
software
available
for
most
popular
computers
.
A
good
understanding
of
your
particular
sequencer
is
essential
before
attempting
to
overdub
lighting
scenes
.
Recording Procedure
1 .)
Connect
three
MIDI
leads
as
shown,
those not
in
operation
at
this
stage
are
shown
in
dotted
lines
.
2
.)
Record
music

tracks
1-3, in
this
case
.

The
music sequence
is
played
back
via the
MIDI
OUT
link
on
the
computer
to
the
keyboard
.

on

as
soon
as
possible
after
step
5
is
completed,
(see
SYNC
function
following
this
section)
.

Information
from
MX
can
now
be
input
in
`real
time'
i
.e
the
music
sequencer
will
recognise
fader/switch
operations
in the
correct
sequence
and
at
the
correct
time
.
These
are
overdubbed
onto
track
4,
just
like
normal

MX
SUPPLEMENT
To
playback
our
automated
music
and
light
sequence,
the
THRU
socket
comes
into
play
.
Playback
Procedure
1
.)
Set
MX
to
MIDI
IN
2
.)
Simply
press
the appropriate
computer
key
to
playback
the
complete
sequence,
light
and
sound
should
be
synchronised
as
required
.
3
.)
Save
the
sequence
if
happy,
if
not
re-record
or
even
overdub
more
lighting
changes
by
following
the
same
procedure
.
Most
sequencers
will
allow
you
to
overdub
on
the
same
track,
so
it
is
quite
possible
to
build
up
complex
and
subtle
lighting
changes
very
easily
.
Computer/Sequencer
nuu~u
Note
:
As
mentioned
earlier,
the
THRU
socket
relays the
signals
from
the
computer
to
MX
via the
MIDI
IN
socket
on
the
musical
instrument
.
Whilst
in
MIDI
IN
mode
most
MX
functions
are
suppressed
and
the
console
becomes
under
the
control
of
the
external
sequencer
or
other
Midi
device
.
The
Grand
Master
and
Blackout
switch take
precedence
over
the
MIDI
controlled
grand
master
and
blackout
switch
in
a
lowest-takes-precedence
manner
.
This
gives
you
the
option
to
shut
off the
console's
output
at
all
times
.
MX
SUPPLEMENT
Issue

During
MIDI
IN
mode,
the
LCD
will
be
fixed
to
a
MIDI
IN mode
display
.
However,
the
MIDI
mode
may
be
changed
to
MIDI
OFF,
MIDI
OUT
or
MIDI
SLAVE
mode
.
Normal
console
operation
can
only
occur
in
MIDI
OFF
and
MIDI
OUT
modes
.
Note
:-
When
the
mode
is
changed
back
to
either
MIDI
OFF
or
MIDI
OUT
mode,
the
output
will
be
controlled
immediately
by
the fader
levels set
on
the
console
.
The
state
of
the console, as
set
by
MIDI
(such
as
effect
control
and
selection
of
operating
modes)
will
be
maintained
when
MIDI
modes
are
switched
.
SYNC
Function
SYNC
records
a
`snapshot
'
of
the
desk
i
.e
it
acts
as
a form
of
reset
signal
by
resetting
the
MX
parameters
shown
back
to
the
state
they
were
in just
before
the
button
is
pressed
.
A
good
illustration
of
this
is
when
used with
our musical
sequence
example
just
explained
.

this

when

applications
the
information
for the
previous
example
setup
is
not
lost
as
it
has
been
stored
with
the
music
sequence
software
.
When
the
example
is
used
again
and
the
sequencer
is
played
back,
the
first
bit
of
information
transmitted
to
MX
will
be
the
code
for resetting
MX
back
to
its
starting
position,
assuming
the
recording
procedure has
been
correctly
adhered
to
.

Slave
Mode
In
this
mode,
it
now
becomes
possible
to
link-up
2
MXs
for
the
purposes
of
increasing
channel
capacity
.
The
maximum
channel
capacity
of
MX
is
48,
should
more
channels
be
desirable,
another
MX
can
be
linked
and
setup via
the
MIDI
ports
.
In
the
configuration
shown,
the
48
way
MX
becomes
the
master
unit
whilst
the
12
way
becomes
the
slave
.
All
controls
on
the
12
way
unit
are
inhibited
apart
from
the
Channel
faders,
Master
faders
and

REMOTE
GO
CUE
It is
now
possible to
remotely
triggerlighting
scenes
that
have
been
pre-recorded
into
the
CD
sequencer
by
means
of
an
external
control
such
as
an
audio
signal,
MIDI
timing
signal
or a
MIDI
PROGRAMME
CHANGE
command
.
This
feature
will
be
extremely
useful
to
any
production
that
has
music
or
sound
effects,
whether
it
beon
tape
orplayed
`live'
by
one
of today's
modern
keyboards
.
Midi
GO
Most
of
today's
keyboard
synthesisers
are
Midi
based
and
are
classed
as
MULTI
TIMBRAL
which means
that
different
instrument
voices
can
play
on
different
MIDI
channels
at
the
same
time
.
Pressing
a button
on
the synth to
change
the
,
voice'
normally
sends
out a
PROGRAMME
CHANGE
command
over
a
MIDI
channel
and
it
is
this
command
that
can
be
utilised
by
MX
.
The
effectiveness
of
the
GO
cue
will
depend
on
the
MIDI
capabilities
of
the
device
used,
some
have
2 or
3
banks
of
buttons
to
change
voices
and
some
have
only
I
or
2
and
need
to
be
programmed
to
change
voices,
but
as
long
as a
PROGRAMME
CHANGE
is
sent
possible
the
GO
cue
will
work
.
EXAMPLE
-
We
wish
to
change
a
lighting
scene
every
time
we
change
voices
.
This
makes
sense,
as
switching
from
a percussive
piano
sound
to
some
lush
sounding
strings
will
obviously
create
a
different
mood
.
