Advanced MIDI In MIDI setup / In Mode.
In previous MIDI control the C Preset only has
access to page 0. In MIDI setup / In Mode the C
Preset has access to all 240 Memory numbers.
Preset C are Sub Masters in MIDI Setuo in /
Slave Mode.
They can be accessed from a range of products
from a cheap keyboard up to the top of the range
sequencer.
Memories from a keyboard.
Program the desk as normal.
Set the Mode Switch to MIDI setup in.
Set the XLS Program Default
to 25 and the
first note on the key board will drive Memory
Number 25. See the table 3 on page 31. The
following 23 notes will drive the following 23
Memory numbers. Set the Program Default to 33
and the first note on the keyboard will drive
Memory Number 33 and the following 23 notes
on the keyboard will drive the following 23
Memory Numbers. This is like changing pages
on the desk except that the block of 24 memories
on Preset C can start from any Memory Number.
Set Program Change
to “NO” to stop the
Program Default being changed by remote MIDI
equipment.
Try setting Program Change to 25 press and hold
the first note on the keyboard. Change Program
Change to 33 Press and hold note two. Note one
has memory Number 25 on it and Note two has
Memory Number 34. Outputs are updated on a
highest takes precedence basis. A MIDI version
of Page overlay operates. Up to 24 keys can be
operated like this, if you have enough fingers, it is
a bit easier on a sequencer.
Access to the Auxillary memory is as ever from
the Colour Note Number upwards on latest takes
precedence basis.
The rest of the XLS operates as a simple 24
channel 2 preset desk with Auxillary memory.

Control from a sequencer in MIDI setup in
Mode.
To run a performance where synchronisation
between the lighting and music is required a
sequencer must be used.
The memories within the XLS are programmed
as normal. Then with the help of the tables 3 and
4 on page 31 annote the script / musical score so
that it shows which Memory Number is required
at what point in time. Program the sequencer
with the Music. Then program in to the
sequencer the Memory Numbers and fader levels
to call up the light outputs. The desk memories
need to be kept. The sequencer can request the
XLS to output any 24 of the 240 Memory
Numbers at any one time and one Auxillary
memory. It is possible to drive more than one
XLS at a time either on the same MIDI channel or
on a different MIDI channel.
What to send to an XLS.
Up to 24 Memory Numbers can be output from
the XLS at a time plus one Auxiliary Memory.
To select which Memory Number is output use
tables 3 and 4 on page 31. The technique used
will differ slightly if the Memory Number is over
127. As Program Changes are limited to 127.
From turn on, in MIDI setup / in Mode, with
Program Change set to “on”, Program Default set
to “1", Channel set up the same on XLS and
Sequencer and the appropriate cables plugged
in. This text will refer to Faders but Note Number
will have to be sent, as per Table 1 page 28.
As set up now driving Preset C fader 1 will drive
Memory Number 1 and fader 2 will drive Memory
Number 2 up to fader and Memory number 24. If
a Program Change of 25 is sent to the XLS then
fader 1 drives Memory Number 25 and fader 2
will drive 26 as shown on Chart 3. If Program
Change 40 is sent then Fader one now drives
Memory Number 40, and fader 2 Memory
Number 41.
If fader one is now held on so the Memory
Number 40 continues to be output and a Program
Change 50 is sent Fader 2 will now drive Memory
Number 51 while fader 1 is still driving 40.
Releasing fader 1 and then replaying it will cause
Memory Number 50 to be output. This is all done
in Bank select 0.
As shown in table 4 on page 31 access can be
gained to Memory Numbers above 127 by using
an extra parameter, Bank select.
In table 4 not all numbers are shown.
By sending Bank Select(BS), Program
Change(PC) and Note Number(NN) (Preset C
fader numbers) Any of the 240 memories can be
accessed. With a maximum of 24 at a time.
There will always be more than one combination
of BS,PC,NN to select any one memory Number.
By careful choice and planning of Memory
Numbers, will reduce the amount of BS and PC
data having to be sent.
Table 4.
Pick a Memory Number. Locate it within a range
of Memory Numbers. The left hand column will
display the Bank Select needed, Down will show
the Program change needed, and up to find the
fader number, Table 1 if completed, will shown
the note number to sent. When more than one
memory is output at a time they are mixed on a
highest wins basis.
Example.
To output Memory Number 50 followed by
Memory Number 145, then remove Memory
Number 50. Memory Number 146 on, All off.
Send BS 1, PC 25, Fader 2 on, BS 5, Fader 1 on,
Fader 2 off, Fader 2 on, Fader 1 off,Fader 2 off.
