FROG Function
The Fixture Random Output Generator
(FROG) function is a special feature on
the desks which affects the outputs of
the colour, beamshape and position
fixture channels.
The user can choose which fixture
channels will output random FROG
values by selecting the required
fixture(s) and attribute (Colour,
Beamshape or Position).
The FROG function only applies to
LTP fixture channels and does not
affect the generic or fixture Brightness
channels on the desk.
The FROG function can be used as a
“live” feature to generate random
outputs on selected fixture channels.
It is also possible to set up fixture
channels to output random FROG
values rather than specific values,
when programming fixture channel
data in memories or submasters.
Therefore, when the memory or
channel data is output via Playback X
or a submaster, the speciallly marked
channels output a random FROG value
rather than a programmed value.
The attributes Colour and Beamshape
can be set to snap or fade between
their FROG values, and have their
minimum and maximum values
adjusted, if required.
With Position, the action and minimum
and maximum FROG values can be
set separately for Pan and Tilt.
The FROG function can be set to
automatic, with an adjustable speed,
manual, with an adjustable fade time,
or Sound to Light, where the trigger is
provided by the bass beat of an audio
signal (Bullfrog only).
Manual mode allows the user to step
through the FROG values using the
STEP button on the front panel.
FROG Output Values
The desk generates 16 different FROG
values for each of the three LTP
attributes (Colour, Beamshape and
Position).
These FROG values apply to all
fixtures and will therefore give different
results with different fixture types.
The minimum and maximum FROG
values for each attribute have been
designed, as far as possible, to avoid
activating Reset or Lamp on/off
functions and extreme positions.
The minimum and maximum FROG
values for each attribute can be
adjusted by the user, if required.
All LTP fixture channels (including
control channels etc.) can be set to
output FROG values, if required.
When a fixture channel is outputting
FROG values, it goes through the 16
pre-defined values in a random order.
Each fixture parameter has its own
independent FROG value chosen at
random from the 16 values for the
corresponding attribute.
However, fixtures of the same type will
all output the same FROG values on
corresponding channels.
For example - If a fixture has CMY
mixing, each of the colour parameters
(Cyan, Magenta, Yellow) would output
its own FROG value. If all three colour
channels were outputting FROG
values this would give a total of 4096
different possible colour combinations.
If the corresponding channels for
several fixtures of the same type were
outputting FROG values, they would all
be outputting the same colours, gobos,
positions etc.
FROG Function Parameters
The following parameters control the
behaviour of fixture channels which are
outputting FROG values.
Mode - Manual, Auto, Sound to Light.
Speed - In Auto mode, the Speed
determines the rate at which each new
FROG value is output (1 - 100).
Fade Time - In Manual or Sound to
Light mode, the Fade Time defines the
time taken to fade to the next FROG
value when the STEP button is
pressed, or a bass beat is received
from the audio signal (0 - 10 secs).
Colour Action - Snap or Fade -
Colour channel behaviour going from
one FROG value to the next.
Colour Minimum - the minimum
FROG value for Colour (0-255).
Colour Maximum - the maximum
FROG value for Colour (0-255).
Beamshape Action - Snap or Fade -
Beamshape channel behaviour going
from one FROG value to the next.
Beamshape Minimum - the minimum
FROG value for Beamshape (0-255).
Beamshape Maximum - the maximum
FROG value for Beamshape (0-255).
Pan Action - Snap or Fade -
behaviour of Pan when going from one
FROG value to the next.
Pan Minimum - the minimum FROG
value for Pan (0-255).
Pan Maximum - the maximum FROG
value for Pan (0-255).
Tilt Action - Snap or Fade - behaviour
of Tilt when going from one FROG
value to the next.
Tilt Minimum - the minimum FROG
value for Tilt (0-255).
Tilt Maximum - the maximum FROG
value for Tilt (0-255).
