Programming Inexpensive Lighting Controllers- Part Two B: Programming Scenes- Strategies

A Theoretical Problem

Say for example I just bought two really sweet new moving head lights. I can't wait to break them out. I've been asked to DJ a wedding reception in the garden atrium of the local swanky hotel. It's going to be a great night. 9:00 PM rolls around, a lot of the older guests have left, and it's time to start the dance party. You fire off the new dance mix of a Taylor Swift song, the dance floor is packed and you fire up the movers! They're moving all around, changing colors, and flashing.  It's like a mini club, and everyone is dancing. It's great! You see the bride's Aunt Wendy doing some sort of worm meets electro-boogie dance in the middle of the floor. You suddenly realize she's actually severely allergic to peanuts and is having some problems. You need to get control of your lights quickly.

We'll explore a few strategies for setting some scenes on your controller. These are just a few ideas I've used that work. They're not the only way to do things but they might be a good starting point.

Know your event

I have recently had to help a few customers program their Chauvet Obey 70 controller, and lights.  One gentleman was a member of a party band, and another customer DJ's a lot of wedding receptions..  We tried to program some scenes that would generally work well for most weddings for both customers.

The first step is to plan ahead. Know your event. Know when things are going to happen. Most wedding receptions follow a similar order. Things start off pretty chill, the bridal party is introduced, there's a father/bride dance, food might be served, a cake is cut, flowers are thrown, and at some point (hopefully) a raging dance party ensues.

Considerations

Since most wedding receptions start off pretty low key, keep the lighting low key.  Let your light show build as the evening builds.  This sets up a few things well.

1. The first dance, father/daughter, etc usually happen early in the evening. If you fire up your movers, lasers, etc during these songs, you risk putting dots of color across the people dancing. Why is this a problem?  It will look weird in the photo album.
2. If you're playing light dinner music and your light show is screaming "Disco Inferno" you might make someone nauseous. The other thing to consider is that your mirror ball might loose it's impact if it  runs all night long. Save it for a special slow song.  You wouldn't play Abba's Dancing Queen all night would you? Then consider cycling lights on and off throughout the evening.
3. If you're using a controller that has multiple layers or scene banks, consider putting a "white" scene on each layer, with your movers pointed straight down at the floor or up at the ceiling. That way if Aunt Wendy goes into a fit, you can quickly bring up lights, pull the movers off the crowd and out of people's faces.

Programming Inexpensive Lighting Controllers- Part Two A: Programming Scenes

In my last post in this series, "Fixtures" I discussed properly addressing lights so that they would correspond with the proper fixture button on the Chauvet Obey series controllers. I've decided to break the scene programming posts into two sections. In the first part I'll just talk about actually programming the scenes. Which buttons to press, and in what order.  The second part I'll actually go over some strategies for creating scenes, so that the controller really works for you, rather than against you.

So How Do We Do This?

Starting off we have to remember that the Obey 10 doesn't have scenes. So we'll skip that one for now. The Obey 40, and 70 do use scene memory, as does the Elation DMX Operator. We need to find the program button.

On the Obey 40 look for the big "Obey 40" logo on the right side. There are two columns of buttons directly to the right of the logo. The Program button is the third button down, on the second column from the right.

The Obey 70's Program button is the top right-hand button, just under the LCD display. If you look for the Obey 70 logo on the right hand side of the console, you'll see two faders directly to the left of the logo.

Now that we have located the Program button, hold it down for three seconds. Boom! Now we are in program mode! This will be indicated by a little light blinking in the lower left hand corner of the LCD Screen.

Programming a Scene

First, select the fixture you want to control. Adjust the faders to create your look. To adjust the first   Then press the "Midi/Add" button.  On the Obey 40, it is located just below the "Program" button.

The Obey 70's "Midi/Add" button is the top left button in the group of buttons located just below the LCD screen.

After you press the "Midi/Add" button, press one of the scene buttons to store your look to a scene. Lights on the controller will blink to let you know the scene is stored. Congratulations! You've programmed your first scene! Now simply repeat this process to create additional scenes.

But Wait, There's More!

If you've created eight scenes and decided you need more, don't worry! The Obey 40 and 70  can each store 240 scenes. There are 30 banks of scenes that you can use. (30 x 8 = 240.) So you can select other banks to store to even after you press the "Midi/Add" button.

To access those other banks, simply locate the "Bank Up" & "Bank Down" buttons. The buttons are located right above the "Program" button on the Obey 40, and to the right of the "Midi/Add" button on the Obey 70. Then press "Bank Up" to move from Bank 1 to Bank 2, and so on. The LCD screen on the controller will indicate what Bank you are currently in.  "Bank Down" will move your bank selection in the opposite direction. Please note that if you are in Bank 1 and press "Bank Down" the controller will move to Bank 30.

That pretty much sums up how to program scenes into these controllers. In the next part of this series I'll discuss some ideas on building scenes that can maximize the use of these controllers, and your lights.

Programming Inexpensive Lighting Controllers- Part One: Fixtures

This post is going to be a little departure from my current series on DMX addressing.   I am going to take some time to focus on programming inexpensive lighting controllers. I'm currently employed at SE Systems in Greensboro, NC. I've worked there part time for the past two years while in classes at Guilford Technical Community College, pursuing degrees in Concert Sound & Lighting, and Recording Engineering. I also serve as a volunteer audio engineer with the production teams at my church. At work, and at church I've run into having to use basic DMX controllers quite often.

The Questions:

SE Systems  carries the Chauvet Obey series controllers, and at my church, we use a Elation DMX Operator controller. I get a lot of questions from customers on setting these up. All of these controllers work basically the same way. There's a series of buttons to select what fixture (light) you want to control. Then there are some faders to control the lights. Then there's  a bank of scenes, and a bank of chases.

What's a Fixture?

Fixture is just a pro lighting world word for a lighting device. It can be a par can, a moving head, a strobe or anything. We also sometimes use the word "instrument." Since these controllers use the word fixture, we're just going to use that for now.

What's a Scene?

A scene is basically a "snapshot" of the way the lights look. Most programmable lighting controllers allow you set multiple scenes, that can be recalled by pressing a button, or series of buttons.

Since we're talking about how the lights look, it's also important to know that lighting designers also use the term "look" a lot. In simple terms, a "look" is the way the fixtures are set- what's turned on, how bright or dim they are, what color they are, where moving lights are positioned-  basically the visual presentation the lights create.  A look is typically saved in, or as a scene.

What about the Chase?

On these controllers, a chase is simply a string of scenes, strung together to play back in a pre-set order. Think of it as a robot in the controller that pushes the scene recall buttons for you, at a pre-set speed.

So How do Fixtures, Scenes and Chases Come Together?

The first step would be to assign the proper DMX addresses to the lights so that they are controlled by the appropriate "Fixture" button on the controller.

In the second step we put the controller in "Program" mode. Select the fixtures you want to control, and adjust the faders to create the look you want. In simple terms, a "look" is the way the fixtures are set- what's turned on, how bright or dim they are, what color they are, what position moving lights are in- the visual presentation the lights create.

Finally, if you're using the Obey 40 or Obey 70 save that look to a scene.  Once you create a few scenes, you can then play back the scenes in a chase.

So short version for the Obey 40 and Obey 70:

Fixture (or group of Fixtures) => Scene (The way you've set the lights to look) => Chase (A Series of Scenes Played Back in an Order)

The Obey 10 doesn't have scenes so you would just program your looks into steps of a chase.

Let's Get Started:

Now we're going to focus on programming the Chauvet controllers. The Elation works the same way, however I just so happen to have an Obey 10, Obey 40, and an Obey 70 sitting on my desk right now.

Chauvet Obey Series Controllers

How It Works:

Each Obey series controller has a series of "Fixture" buttons on it. The Obey 10 has eight buttons. The Obey 40 and Obey 70 have twelve buttons. Each of the fixtures are controlled by the faders in the center of the controllers. The Obey 10 and Obey 40 can control up to 16 channels per fixture. The Obey 70 controls up to 32 channels per fixture.

On the Obey 10 and Obey 40 the fixture I want to control as Fixture 1 would be given DMX address 001. These controllers give you 16 faders, or control channels per fixture. We have to add 16 to the first address so that our second fixture doesn't end up with channels being controlled by the Fixture 1 controls on the controller. To assign the  Fixture 2 controls to control our second fixture, its address should be DMX channel 017. The Fixture 1 on an Obey 70 would also be 001, but because the 70 has 32 channels of control, Fixture 2 would have to be addressed as 033.

The charts below should make this a little clearer. The numbers in the left column correspond to the Fixture button on the controller.  The "Uses Addresses" column tells what DMX channels that fixture number uses.  The final column indicates what DMX address should be assigned to the unit that you want to be controlled by the fixture button.  For example on an Obey 10, to use a light as Fixture number 3, you would give it the DMX address 33.

Hope this helps shed some light (yes, the pun was intended) on how to address your lights to use with the Chauvet controllers.  We'll take a look at creating scenes on the next post.
