Introduction
This Manual
This manual describes the operation and programming of the JesterML and
JesterML24 lighting desks. It begins with a general description of the desks, the
master controls, turning on the desk and the default state. The main sections cover
the different operating modes of the desk, namely PRESET, PROGRAM and RUN.
Each of these sections contains a basic description of the relevant front panel
controls and displays, and a step by step guide to the various functions available.
The manual then moves on to more specific areas of the desk such as Fixture
Control, and concludes with sections on the SETUP functions and the technical
specification of the desk.
Certain functions (notably Presets and Submasters) are only available on the larger
JesterML24 desk. For clarity, this manual refers to both desks as simply ‘JesterML’ -
where differences exist between the two desks, these will be noted in the text.
The JesterML
The JesterML lighting desk is a compact user-friendly memory desk which records
channel levels and fixture information, and provides both theatre style sequential
memory access and sub-master (JesterML24 only) style access. Memories and
Submasters can be recorded as scenes or sequences (chases). Crossfade times
and chase speed, direction and attack can be adjusted as required. The JesterML
can control 30 intelligent fixtures (moving lights). The JesterML24 adds 24 generic
(dimmer) control channels to this. The output from the desk is by DMX512-A only.

Introduction JesterML Operating Manual
73-406-00 Issue 1.0 5 of 65
Master Controls and Displays
These controls set the general operating conditions for the desk.
MODE
The MODE button is used to select the operational mode of the desk. The red LEDs
to the left of the button show the current operating mode (SETUP, PRESET,
PROGRAM, RUN).
GRAND MASTER
The GRAND MASTER fader is used for overall control of the maximum output levels
from all brightness channels of the desk.
BLACKOUT
The BLACKOUT button makes all the brightness channels output zero. Pressing the
BLACKOUT button toggles between Blackout (all channels at zero) and normal desk
outputs. The LED in the BLACKOUT button indicates the current state (Flashing =
Blackout, Off = Normal). This is also replicated on the monitor, with flashing
‘BLACKOUT’ text on the screen. Both Blackout and the Grand Master do not affect
LTP (fixture attribute) channels and DMX-input.
PROGRAM/GO
The PROGRAM/GO button is a multi-coloured, multi-function button which adapts to
the mode in which the desk is currently set. In Preset Mode, the button is inactive
although when set to wide mode, it functions as a preset store button, and is
coloured yellow. In Program Mode, the PROGRAM/GO button functions as a
program (record) button, and is coloured red. In Run mode, the PROGRAM/GO
button acts as a go/pause button and is coloured green.
Turning on the Desk
1. Connect the DMX cable and monitor (if required). Although the monitor is
optional, you will find the desk easier to use with a monitor attached.
2. Connect the power supply to the desk and switch it on at the mains.
3. Ensure that ‘Blackout’ is not active (the red LED in the Blackout button is off).
4. Set the A MASTER and B MASTER faders to zero.
5. Set the GRAND MASTER fader to full.
Numeric Entry
Numeric fields can be completed by using the Multi-Function-Keys. On the
JesterML24, the CHANNEL FLASH buttons on preset B can also be used for this
purpose. Firstly navigate to the required field, then press ENTER. The Multi-
Function-Keys (and channel flash buttons on the JesterML24) now function as
number buttons. Once the number is entered, press ENTER to confirm.

JesterML Operating Manual Preset Mode
6 of 65 73-406-00 Issue 1.0
Preset Mode
PRESET Mode allows direct control of the fixtures, replay of palettes, and control of
the 24 preset faders (JesterML24 only).
When the desk is in PRESET Mode all the memory functions are disabled, offering a
completely manual control system. The desk can be operated using either two 12
channel presets each controlling 12 channels, or a single preset controlling 24
channels. In Two Preset operation, separate scenes are set up on PRESET A and
PRESET B using the individual channel faders. The A MASTER and B MASTER
faders are used to crossfade between the two scenes.
With wide mode selected (13-24 active on the bottom bank, PAGE B) it is still
possible to crossfade between two scenes. The first scene is set up on the PRESET
A and PRESET B faders and is stored in the desk temporarily using the yellow
PROGRAM/GO (Store) button. Once stored, another scene can be set up on the
PRESET A and PRESET B faders.
The A MASTER and B MASTER faders are used to crossfade between the stored
scene and the scene on the PRESET faders. Crossfades between scenes can be
manual or timed. As with all operating modes of the desk, overall output is under the
control of the GRAND MASTER.
PRESETS A AND B (JesterML24 only)
There are 12 PRESET A faders which control individual channels 1 -12 and 12 PRESET B faders
which control individual channels 1 -12 or channels 13 - 24 if the faders are switched to wide mode.
CHANNEL FLASH BUTTONS (JesterML24 only)
There are 24 CHANNEL FLASH buttons corresponding to the 12 PRESET A and 12 PRESET B
faders. These are used to flash individual channels. By selecting SPECIAL, these buttons can be
disabled, or switched to SOLO mode.
A MASTER AND B MASTER
In two preset mode, the A MASTER controls the output level from the PRESET A faders and the B
MASTER controls the output level from the PRESET B faders. In wide mode, the A MASTER and B
MASTER faders control the output level from both the PRESET A and PRESET B faders, and the
stored scene. The B MASTER is reversed (100% at the bottom of its travel) to facilitate manual
crossfades when moving the A MASTER and B MASTER in tandem.
FADE TIME
The fade time is set using the wheels when SPECIAL is selected, and determines the fade time when
crossfading between scenes. The control can be set to Manual or to a time between 0.1 second and 5
minutes. This time is indicated on the LCD above the wheels. The PROGRAM/GO button (used as a
STORE button will blink yellow when a timed crossfade is taking place.
PROGRAM/GO
The PROGRAM/GO button is used in wide mode as a STORE button. This button is used to control
which master (A MASTER or B MASTER) has control of the PRESET faders, and which master has
control of the stored scene. The Main LCD indicates the current state (A FADERS, B STORED or B
FADERS, A STORED).

73-406-00 Issue 1.0 7 of 65
Two Preset Operation
In two preset operation the PRESET A and PRESET B faders, the A MASTER and B
MASTER and the GRAND MASTER are used to control the output levels from the
desk. The fade time set with the middle wheel when SPECIAL is selected, is used to
determine the crossfade time between the preset masters.
Setting up for Two Preset Operation
1. If the desk is not already in PRESET Mode, press and hold the MODE button for
1 second. The PRESET LED next to the MODE button will come on.
2. Ensure the bottom bank of faders are set to 1-12(24) mode and the fade time
(press SPECIAL and use the middle wheel) is set to Manual.
To Output a Scene from Preset A
1. Set the required levels for each channel on the PRESET A faders.
2. Set the A MASTER to full. The scene set up on PRESET A is output live.
To Output a Scene from Preset B
1. Check that the B MASTER is set to 0.
2. Set the required levels for each channel on the PRESET B faders. This action is
performed without the output levels of the desk changing.
3. Set the B MASTER to full. The scene set up on PRESET B is output live, mixed
with the scene on PRESET A.
4. To remove the scene on PRESET A, bring the A MASTER to zero.
Manual Fading between Scenes
1. Ensure that the fade time (press SPECIAL and use the middle wheel) is set to
Snap.
2. Set up a scene using the PRESET A faders.
3. Set the A MASTER to full, and the B MASTER to zero. The scene set on the
PRESET A faders will be output.
4. Set up a different scene on the PRESET B faders. This is done blind, without the
output levels changing.
5. To crossfade to the new scene set up on PRESET B, simultaneously move the A
MASTER to zero and the B MASTER to full. You have direct control over the
speed of the crossfade. As the master faders are moved in tandem the scene
setup on PRESET B will fade in and the scene set on PRESET A will fade out.
This crossfade is dipless.
6. A new scene can then be set up on PRESET A without affecting the outputs.
7. To crossfade to the new scene on PRESET A, simultaneously move the A
MASTER to full and the B MASTER to zero.
8. As the A and B master faders are moved in tandem the scene set up on PRESET
B will fade out and the new scene set on PRESET A will fade in. The crossfade is
dipless.

3. Set up a different scene on the PRESET B faders.
4. Set the fade time required to fade scene A in, by pressing SPECIAL and moving
the middle wheel.
5. Quickly move the A MASTER to full. The scene on the PRESET A faders will
fade in and be output live. (The time taken for the fade to complete is determined
by the fade time setting).
6. The STORE button will blink yellow while the dipless crossfade is taking place.
7. To crossfade to the scene on PRESET B, quickly move the A MASTER to zero
and the B MASTER to full. The scene on PRESET B will fade in and the scene
on PRESET A will fade out in the set fade time. The STORE button will blink
yellow while during the crossfade.
8. A new scene can then be set up on PRESET A without affecting the outputs.
9. To crossfade to the scene on PRESET A, quickly move the A MASTER to full and
the B MASTER to zero. The scene on PRESET A will fade in and the scene on
PRESET B will fade out in the set fade time. The STORE button will blink yellow
while the dipless crossfade is taking place.
Flashing Channels – Two Preset Mode
1. Ensure that the Flash function is active – this is set using the Multi-Function-Keys
when SPECIAL is selected.
2. Press and hold an individual CHANNEL FLASH button. (Those below the
PRESET A faders or PRESET B faders can be used). The channel is then added
to the scene at the level set on the GRAND MASTER.
3. Release the CHANNEL FLASH button. The channel returns to its previous
(fader) level.
FLASH: The selected channels will be sent to full when the button is pressed, and
will be returned to its fader level when the button is released. No other channels are
affected.

will be sent to blackout. When the button is released, all brightness channels are
returned to their normal levels.

Preset Mode JesterML Operating Manual
73-406-00 Issue 1.0 9 of 65
Wide Mode
When operating in Wide Mode, you are able to crossfade between or combine two
scenes which are 24 channels wide. A scene is set up using the PRESET A and
PRESET B faders. The PRESET A faders control channels 1 -12 whilst the PRESET
B faders control channels 13 - 24.
This scene is then stored temporarily by pressing the PROGRAM/GO (STORE)
button. A second scene can then be set up on the PRESET A and PRESET B
faders. The A MASTER and B MASTER faders can then be used to crossfade
between the two scenes. The PROGRAM/GO button is used to control which master
has control of the PRESET channel faders, and which the stored scene.
The GRAND MASTER is used to control the final output levels from the desk.
The fade time set when SPECIAL is selected is used to determine the crossfade time
between the two scenes.
Setting up for Wide Operation
1. If the desk is not already in PRESET Mode, press and hold the MODE button for
1 second. The PRESET LED next to the MODE button will come on.
2. Activate Wide Mode. To do this, ensure that PAGE B is set to channels 13-24.
On first invoking wide, the PRESET faders will be assigned to the A MASTER,
and the stored scene assigned to the B MASTER. The Main LCD will indicate
this (A FADERS, B STORED). The temporarily stored scene will be cleared.
Storing and Cross Fading Scenes
1. Set the A MASTER and GRAND MASTER to full and the B MASTER to zero.
Press SPECIAL and set the fade time to Snap using the middle wheel.
2. Ensure that the Main LCD indicates A FADERS, B STORED (if there is no
indication on the Main LCD, you’re not in Wide mode, and if the Main LCD
indicates B FADERS, A STORED, press the PROGRAM/GO button)
3. Set up a scene using the PRESET A and PRESET B faders. This scene will be
output.
4. To store the scene press the PROGRAM/GO button, which in preset mode is
coloured yellow to indicate its function as STORE. The fader levels are
temporarily stored and the Main LCD will change to indicate B FADERS, A
STORED. The A MASTER is now assigned to the stored scene and the B
MASTER assigned to the faders, so the outputs remain the same.
5. Set up the next scene using the PRESET A and PRESET B faders. (The outputs
are not affected since the B MASTER is currently at zero).
6. To crossfade between the stored scene and the scene on the PRESET faders,
simultaneously move the A MASTER to zero and the B MASTER to full. A
dipless crossfade will occur.
7. If the PROGRAM/GO button is pressed again, the output levels are saved into the
temporary store (overwriting the previous values) and the Main LCD will change
to indicate A FADERS, B STORED. The B MASTER is now assigned to the
stored scene and the A MASTER assigned to the PRESET faders, so the outputs
remain the same.
8. The operations described in steps 5 - 8 can then be repeated to set up a new
scene on the faders, crossfade to the new scene, and save it to a temporary store
etc.

Manual and Timed Crossfades
Crossfading between the scene set up on the PRESETS and the stored scene is
achieved by moving the A MASTER and B MASTER faders in tandem. If the fade
time set when SPECIAL is selected is set to Snap, the crossfade time is determined
by the speed at which the A MASTER and B MASTER faders are moved. You have
direct control over the speed of the crossfade.
The crossfade time can be changed from 0.1 seconds and 5 minutes using the
middle wheel when SPECIAL is selected.
Flashing Channels - Wide mode
1. Ensure that the Flash function is active – this is set using the Multi-Function-Keys
when SPECIAL is selected.
2. Press and hold an individual CHANNEL FLASH button. The buttons below the
PRESET A faders control channels 1 - 12, those below the PRESET B faders
control channels 13 - 24. The corresponding channel is then added to the scene
at the level set on the GRAND MASTER. Dependant on the flash mode, the
other channels may or may not be affected – see below.
3. Release the CHANNEL FLASH button. All channels return to their previous level.
FLASH: The selected channels will be sent to full when the button is pressed, and
will be returned to its fader level when the button is released. No other channels are
affected.
SOLO: The selected channels will be sent to full and all other brightness channels
will be sent to blackout. When the button is released, all brightness channels are
returned to their normal levels.
NOTES
Stored Scene
Any stored scene being output in PRESET Mode will be removed from the outputs if
the desk is changed to PROGRAM, RUN or SETUP Modes.

Program Mode JesterML Operating Manual
73-406-00 Issue 1.0 11 of 65
Program Mode
Introduction
Program Mode on the desk is used to select and create new memories or
submasters (JesterML24 only) and enter moving light data into Palettes. Once an
item has been created it can be modified within Program Mode, and the contents re-
stored.
Memory Types
There are two memory types which can be programmed on the JesterML desk. They
are SCENE memories and CHASE memories.
A SCENE memory consists of a single static state, recording the output look.
A CHASE memory consists of a number of steps (maximum of 999). Each step
consists of a single static state, recording the output look.
The up or down cursor buttons are used to select the required memory, whilst the
Main LCD displays the <Mem:> field. The Main LCD shows the selected memory
number, along with its associated fade time(s) and its name. If the memory being
programmed is a CHASE, the Main LCD also shows the current step number. The
fixture controls (and PRESET faders on the JesterML24) are used to set the output
look and the PROGRAM/GO button used to save the look to memory.
Submaster Types (JesterML24 only)
Scenes and Chases can also be recorded onto Submaster faders. These faders
allow you to fade in scenes or chases on a single fader, whilst in Run mode.
Pressing a Channel Flash button whilst in Program Mode allows you to select the
required submaster for programming. The JesterML24 has 2 pages of 12
submasters, totalling 24. In Program mode, PRESET A represents submasters 1-12
and PRESET B represents submasters 13-24.
Low Memory Warning
The JesterML has a maximum capacity of 500 memories, plus 24 submasters, plus
30 each of Colour, Beamshape and Position palettes. Each memory may be a
SCENE or a CHASE. The number of CHASE steps, or a large number of fixture
channels in use, may cause the total number of memories to be less than 500. The
desk software monitors the amount of memory used and displays a warning when
the memory available is getting low, and when there is none left.
NOTES
Tagging
By default, all fixture intensities (and desk channels on the JesterML24) are recorded
into every memory or submaster, and are mixed on a highest-takes-precedence
(HTP) basis when replayed. Fixture parameters (LTP channels) are only recorded if
they are tagged. This behaviour can be changed in Setup (Record Options) if
required.
It is very important to consider what is tagged when working with moving lights.
Further details are given in the section on Fixture Control, which it is recommended
that you read fully.

JesterML Operating Manual Program Mode

Program Controls and Displays
PRESET A AND PRESET B (JesterML24 only)
There are 12 PRESET A faders which control individual channels 1 -12. There are 12 PRESET B
faders which control individual channels 13 - 24.
CHANNEL FLASH BUTTONS (JesterML24 only)
Each of the PRESET faders has a corresponding CHANNEL FLASH button. They are used to select
a submaster for editing.
A MASTER and B MASTER
The A and B MASTER faders are disabled in PROGRAM mode.
Main LCD
The Main LCD indicates the selected memory, submaster or palette number and the current step
number (if applicable). An asterix (*) after the number indicates that the item is unprogrammed, whilst
a plus (+) indicates the memory or submaster includes captured DMX data from the DMX-in port.
DMX-Input data is not recorded into palettes.
MONITOR
The monitor displays the selected memory or submaster with a yellow bar and the current step
number, in the ‘steps’ column. An asterix (*) after a number indicates that the item is unprogrammed.
Names for both submasters and memories are displayed on the monitor output, as are the fade up &
down times for a memory, and the output levels.
CLEAR
This button is used to clear a memory, submaster or palette, or to clear a step from a chase
memory/submaster. Hold the button for 1 second to delete a scene, step or palette, hold for 1s with
SHIFT to delete a chase, and tap to backspace when entering names.
PROGRAM/GO
In Program Mode, this button is used to save the output levels and fade times into the selected
memory or submaster (no fade times are stored for submasters or palettes). If the memory or
submaster is a chase, the output levels are saved into the current step and the chase modifiers are
stored for the entire chase.
EDIT
This button loads the currently selected item onto the outputs. If it is a chase, then the chase is run.
When EDIT is active, the LED in the button is lit. To save changes back to the original location, simply
press the button again, and the LED will go out. To save changes to a new location, first select that
location using the cursor buttons for a memory, or flash buttons for a submaster (JesterML24 only), or
Multi-Function-Keys for a palette, and then press PROGRAM/GO. Again the LED will go out as the
desk is no longer in edit mode. This provides a Copy function.
The EDIT button also works in RUN Mode, so that quick edits can be made to the selected
memory/submaster, with the desk returning automatically to RUN Mode once the edit is complete.

NOTES
Editing ‘Live’
When changing from RUN Mode to PROGRAM Mode, it is the NEXT memory which
will be selected for editing. To make an edit to the current memory without sudden
output changes, simply set the NEXT memory to the same as the CURRENT
memory, before changing from RUN Mode to PROGRAM Mode.
Selecting a Memory Number
The Main LCD shows the selected memory number <Mem: #>. This is replicated on
the monitor by the selection having a yellow bar.
An unprogrammed memory has an asterix (*) after the memory number. An
unprogrammed memory is always a scene memory, but can be converted to a chase
easily. The up or down cursor buttons are used to select the required memory
number to program.

6. Press the PROGRAM/GO button to save the current output levels. The first time
you do this, the Main LCD will ask you if you wish to overwrite the existing
memory, convert the memory to a chase, or cancel the operation. Use the cursor
buttons to select the <Make Chase> option, and press ENTER. The current
outputs will be stored as step2, and the desk will increment to show step3 as the
next available step.
7. Repeat steps 5 and 6 until all steps in the Chase have been programmed.
8. Press the left cursor button to move away from the <Step> field, and back to the
memory/submaster number.
9. Press EDIT and the chase will start to run sequentially. Ensure CHASES is
selected, and adjust the speed by using the middle wheel. If required, you can
also adjust the following using the Multi-Function-Keys:
• Direction: Forwards, Backwards, Bounce or Random
• Brightness Attack: Snap, Ramp Down, Ramp Up, or CrossFade
• Colour/Beamshape/Position Attack: Snap or Fade
NOTES
Tagging and Chases
All steps of a chase must have the same Tag states when programming in Partial
Mode. To ensure this, the tags from the most recently programmed step (regardless
of it’s position in the chase) are used for the entire chase.
The JesterML automatically clears the tag states after programming a scene
memory. When <Make Chase> is selected, the JesterML merges the tag states from
the scene (Step 1) with the new tag states (Step 2). The JesterML does not
automatically clear the tag states when you program subsequent steps.

NOTES
Adding Steps
A new step cannot be added until the current step has been saved by pressing
PROGRAM/GO
Renumbering Steps
Any original steps in a Chase after an inserted step will be renumbered accordingly.
For example, if you started with a 10 step Chase and added a step between steps 4
and 5, the new step becomes step 5 and the original steps 5 - 10 become steps 6 -
11. Any steps in a Chase after a deleted step will be renumbered accordingly. For
example, if you start with a 10 step Chase and delete step 5, original steps 6 – 10
become steps 5 - 9.
Inserting Steps
The INSERT button can only insert a step after the current step. If you wish to insert
a step before Step 1 of a Chase then following actions must be performed: Select
Step 1 and press the EDIT button. Insert a new step after Step 1 using the INSERT
button. Press the PROGRAM button to save the contents of Step 1 to the new Step
2. Set up the new look for Step 1, and re-program it using the PROGRAM button.

NOTES
Viewing Steps
It is possible to scroll through the steps of a chase memory or submaster, using the
cursor up or down buttons when the Step field is selected. Steps are output by
pressing the EDIT button.
DMX Input
The JesterML allows you to input a full universe of DMX and capture this to any
memory or submaster (JesterML24 only), allowing the JesterML to act as a backup
console. When a DMX input is attached to the desk, the JesterML automatically re-
transmits any unpatched channels on the DMX output. Channels which are patched
to the Preset Faders (JesterML24 only) are mixed highest-takes-precedence.
Channels which are patched to the Fixtures are ignored – for this reason it is
recommended that when using as a backup console, that no fixtures are patched.
When a memory (or submaster) is recorded with a DMX-input present, the memory
(or submaster) will store all 512 channels, including any unpatched channels. The
memory or submaster will show a +, to indicate the additional data has been stored.
This will then act as a backup memory or submaster, allowing you to replicate the
scene at any required time.
Note that DMX-In channels do not crossfade their outputs and instead trigger when
the memory or submaster is triggered. DMX-Input is not recorded into palettes.

Run Mode
Introduction
Run Mode on the desk is used to replay the previously recorded memories,
submasters (JesterML24 only) and palettes. The programmed memories are stored
in a stack and can be replayed one at a time in ascending numerical order. This
allows the complete show to be replayed in order, simply by pressing the
PROGRAM/GO button. The cursor buttons can also be used to select a particular
memory, which can then be output by pressing the PROGRAM/GO button. The Main
LCD shows the current and next memory to be output.
The crossfade time, chase speed and attack can be adjusted using the various front
panel controls. The brightness output levels are determined by the programmed
levels in the memory, the MEMORY MASTER and the GRAND MASTER.
The brightness levels in a Submaster (JesterML24 only) are controlled directly by the
submaster and the GRAND MASTER – fixture parameter (LTP) channels are
triggered when the submaster fader is raised above 5%.
Run Mode Controls and Displays
PRESET A AND PRESET B (JesterML24 only)
There are 12 PRESET A faders which control individual channels 1 -12. There are 12 PRESET B
faders which control submasters.
CHANNEL FLASH BUTTONS (JesterML24 only)
The 12 CHANNEL FLASH buttons corresponding to PRESET A are used to flash presets 1-12 or 13-
24, depending on the Page A setting.
The 12 CHANNEL FLASH buttons corresponding to PRESET B are used to flash submasters 1-12 or
13-24, depending on the Page B setting.
By selecting SPECIAL, these buttons can be disabled, or switched to SOLO mode.
A MASTER AND B MASTER
The A MASTER is used to control the maximum output level from the PRESET A faders. The B
MASTER fader is inactive in RUN mode.
MEMORY MASTER
The MEMORY MASTER fader is used to control the output level of the brightness channels in the
current memory in the stack.
FADE TIME
The fade time setting (set using the wheels when SPECIAL is selected) is used for several things in
RUN Mode: To determine the rate at which the current memory will fade out and next memory fade in
when the PROGRAM/GO button is pressed, and to determine the fade time of submasters
(JesterML24 only) and the PRESET A master. Palettes are replayed instantly (Snap) without a fade
time.
Main LCD
The Main LCD shows details of the current and next memory to be output. If a submaster is selected
(JesterML24 only) then the name of that submaster will be displayed.
