Sequencing Lights

This is where the rubber meets the road. Sequencing simply means telling a program what lights you want to turn on when. 

You don’t need a song yet, but it’s more fun if you have one. Make sure it is an MP3 (not an mp4 or aac or other audio format). For example, I am using iTunes and I had to click File->Create New Version->Create MP3 Version to get my song to work.

Start up the LOR Sequencer and give it your MP3. There are a couple wizards you can use here to get the basic beat. The Beat Wizard (which most seem to have a love/hate relationship with) is not a bad place to start, results vary greatly depending on the song. I assume this is why a lot of people use techno songs with hard constant beats, they make sequencing a lot easier. Eventually, though, you will probably want to switch to the Tap Wizard. Each wizard generates a Timing Grid, basically a click track that you can attach light events to. For my first song I just did the Tap Wizard and clicked my mouse whenever I felt like something should happen. That gave fairly pleasing results for a first pass.

You can have multiple Timing Grids that you can switch between so there is no harm in trying lots of different things. If you use the Beat Wizard, I would add 4x or 8x on the timings. This gives you quarter or eighth notes to time your lights to.

Now you have a grid that you can click lights on and off, fade in, and fade out. Click "Play" to see what happens.

Nothing.

Sneakily you have to select the “Play” menu and tell it to control your lights. If you don’t have your lights connected you can also tell the “Play” menu to “Control Visualizer”. Oooh, what’s that?

Start up LOR Visualizer and draw in your strands of lights as you think they might look in your yard. Accuracy is not too important here. I drew in four vertical lines, my roof line, and a tree. Now right click on the things you drew and select “Properties”. Down at the bottom you will see “Assigned Channels”. Select “Light-O-Rama Controller” for the device and the channel number (“circuit”). Save all that, and click Play.

Again nothing.

That’s OK. Go back to the Sequencer and verify you’ve still got “Control Visualizer” selected in the Play menu. Now click "Play" again in the Sequencer and you should see your Visualizer window start dancing. Congratulations! You are a computer programmer.

There is a lot more to sequencing which entire magazines and classes have been devoted to so I wont go into great detail here. Hopefully this got you started. I’ll try to write about any clever tricks I’ve found, but the best way to learn is look at other people’s sequences and see what they did.  

Lightorama.com has a lot of videos, so does YouTube. Here's one from CrazyChristmasCrew's excellent 15 part Vlog chronicling the creation of his show. It's a great peek into the effort required to put on a great show.

Glossary:

Timing Grid: Often beats in the music, timings are anchors where you can turn lights on and off.

Sequencing: Creating a sequence of actions on a grid that turn your lights on and off.  Since you have to control so many lights and so many musical beats, this can consume months of time.  It is the reason people say “I started my show in June”.

Wizards: Tools to help make sequencing easier.  Beat, Tap, and VU are a few tools to create timings to your music. There are many more.
