Set up a binding so the state of a cue gets communicated via OSC, and record that we did that so it can be cleaned up later. Then set up so that incoming OSC messages can start and end that cue.

Arrange to send an OSC message whenever the value of a show variable changes, and record that we did that so it can be cleaned up later. Then set things up so incoming OSC messages update the value of that variable.

If you need to do anything more complicated than send a message with the raw value of the variable, or update the variable with the raw first value from the incoming OSC message, you can pass your own functions with the optional keyword arguments :send-fn and :receive-fn. :send-fn will be called with the keyword identifying the variable that has changed, and its new value. :receive-fn will be called with the incoming OSC message.

If you want this binding to not affect reception of messages on the OSC path (for example because you have another variable binding set up which processes these messages, since they contain values for multiple show variables), then pass :none as the value for :receive-fn.

Create a scene which sets the color of one light, and aims it just below and in front of another.

Helper function which builds the common variables needed to create a cue which runs on either all lights or a named group of lights.

Creates a dynamic parameter for setting the beat ratio of one of the dimmer oscillator cues in make-cues by forming the ratio of the cue variables introduced by the cue. This allows the show operator to decide over how many beats the oscillator runs, and how many times it cycles in that interval.

Expects the cue’s variable map to contain entries :beats and :cycles which will form the numerator and denominator of the ratio. If any entry is missing, a default value of 1 is used for it.

A effect that moves the blades like they are in a kick line.

The location of the ceiling on the show Y axis.

Create a chase that generates a series of circles on either the floor or the ceiling, causing a single head to trace out each, and passing them along from head to head.

The number of bars taken to trace out each circle defaults to 2 and can be adjusted by passing a different value with the optional keyword argument :bars. The radius of each circle defaults to one meter, and can be adjusted with :radius. If you want each head to be tracing a different position in its circle, you can pass a value between zero and one with :stagger.

Clear out any OSC cue bindings which have been established.

Clear out any OSC var bindings which have been established.

Create a sequential chase which gradually takes over all the moving heads from whatever they were doing, changes their colors, and makes them cross in an interesting pattern. By default, stages of the chase advance on every beat, but you can adjust that by passing in a different value for with the optional keyword argument :beats. To add a fade between stages, pass a non-zero value (up to 1, which means continually fade) with :fade-fraction.

The color used during the crossover stages defaults to red, but you can pass a different color object to use with :cross-color.

An effect which uses an oscillator to move a bar of light across a group of fixtures. The width of the bar, maximum dimmer level, and whether the level should fade from the center of the bar to the edge, can be controlled with optional keyword arguments.

Start simple with a cool blue color from all the lights.

Make a color effect which affects all lights in the sample show. This became vastly more useful once I implemented dynamic color parameters. Can include only a specific set of lights by passing them with :fixtures

Return an effect that sets all the dimmers in the sample rig. Originally this had to be to a static value, but now that dynamic parameters exist, it can vary in response to a MIDI mapped show variable, an oscillator, or the location of the fixture. You can override the default name by passing in a value with :effect-name

Create a page of cues for controlling lasers, and ambient effects like the H2O LED and black light. Also adds copies of the important cue for opening Torrent shutters and resetting their motors.

Also holds cues for turning on sound active mode when the show operator wants to let things take care of themselves for a while, and doesn’t mind losing the ability to control show brightness via dimmer masters.

Create a cue-grid entry which establishes a global color effect, given a named color. Also set up a cue color parameter so the color can be tweaked in the Web UI or on the Ableton Push, and changes can be saved to persist between invocations.

Create a bunch of example cues for experimentation. If Beyond laser show integration is desired, add-beyond? will be true. If Open Sound Control integration is desired, add-osc? will be true.

Creates a cue which lets the operator adjust the dimmer level of a group of fixtures. Group will be one of the values in light-groups, or nil if the cue should affect all lights.

Create a page of cues for aiming lights in particular points, individually and in groups. If add-osc? is true, make them controllable over Open Sound Control.

Creates a page of cues that assign dimmers and colors to the lights. This is probably going to be assigned as the first page, but can be moved by passing non-zero values for page-x and page-y. If Beyond laser show integration is desired, add-beyond? will be true. Similarly, if Open Sound Control integration is desired, add-osc? will be true.

Create a page of cues for aiming lights in particular directions, individually and in groups.

Create a page of with some large scale and layered movement effects. And miscellany which I’m not totally sure what to do with yet.

Create a cue which applies a sawtooth oscillator to the dimmers of the specified group of fixtures, with cue variables to adjust the oscillator parameters.

Create a cue which applies a sine oscillator to the dimmers of the specified set of fixtures, with cue variables to adjust the oscillator parameters.

Create a cue which applies a square oscillator to the dimmers of the specified set of fixtures, with cue variables to adjust the oscillator parameters.

This is no longer used in the sample cue set, but is left as an example in case you want to create a strobe cue that depends only on numeric parameters, rather than the newer color parameter capabilities.

Create a cue which strobes a set of fixtures as long as the cue pad is held down, letting the operator adjust the lightness of the strobe color by varying the pressure they are applying to the pad on controllers which support pressure sensitivity, and having the base strobe color depend on a set of shared numeric show variable.

Create a cue which strobes a set of fixtures as long as the cue pad is held down, letting the operator adjust the lightness of the strobe color by varying the pressure they are applying to the pad on controllers which support pressure sensitivity, and having the base strobe color depend on a shared show color variable. On controllers which support it, the color of the cue pad will be also driven by this shared color variable, with a white flicker to emphasize them as strobing cues.

Create a page of cues for configuring aspects of the Torrent F3s and another to its right for their gobo selection.

Create a cue which applies a triangle oscillator to the dimmers of the specified set of fixtures, with cue variables to adjust the oscillator parameters.

Allow us to send messages to an OSC interface like TouchOSC.

Keep track of any OSC cue bindings we have set up, so we can clear them out before re-creating the show.

Shut down osc server and clean up.

Keep track of any OSC var bindings we have set up, so we can clear them out before re-creating the show.

An example of how to patch a whole group of lights with a parameterized location. We mount our lights on our lighting rig in standard positions, so knowing the position of the rig and the height to which it has been adjusted allows us to figure out where all the lights are on it.

For the moment the orientation of the rig defines the orientation of the show, and the origins of the show axes are the spot on the floor underneath the center of the horizontal truss. The z axis increases towards the audience from that point.

Because the height of the rig can be adjusted, you can pass in a value with :y to set the height of the center of the lower bar on the horizontal truss. If omitted a default height of 62.5 inches is used, which is approximately the height of the bar when the extension poles are collapsed for load-in and strike.

We try to hang blades 1-4 at an angle of 72.5 degrees leaning towards the audience, and blade 5 sags to about 101 degrees but if any angle ends up being off and difficult to correct, it can be passed in with :blade-1-angle through :blade-5-angle The actual mounting height of blade 5, if it differs from 4 inches can be passed with :blade-5-height.

Fixture numbers are assigned stage left to stage right (looking at the lights from behind the rig), except for blade 5, which is an extra which is sometimes placed in the middle.

It would be possible to extend this function to support positioning and rotating the truss within show space, now that patch-fixture allows you to pass in a transformation matrix. But until that complexity is needed, this simpler approach seems practical. The truss is the main component of our show, so having it be at the origin makes sense.

The height of the center of the bottom horizontal truss bar of the main lighting rig as set up in the current venue.

Create some cues that integrate Pangolin Beyond. Assumes sample show has been created, and takes the beyond server to work with as an argument.

Set up the show laid out for Chris. By default it will create the show to use universe 1, but if you want to use a different universe (for example, a dummy universe on ID 0, because your DMX interface isn’t handy right now), you can override that by supplying a different ID after :universe.

Set up a sample show for experimenting with Afterglow. By default it will create the show to use universe 1, but if you want to use a different universe (for example, a dummy universe on ID 0, because your DMX interface isn’t handy right now), you can override that by supplying a different ID after :universe.

Usually we run our shows on a single universe, but sometimes we connect the Weather System fixtures to an extra universe, and wire them separately from the main lighting rig. When we do that, we can pass the extra universe ID in after :extra-universe.

If you have an instance of Pangolin Beyond running a laser show that you want to control as well, pass a true value with :add-beyond?. If you don’t want to experiment with Open Sound Control, you can pass a false value with :add-osc?.
