Best setup Qlab/dmx/servo control / launchpad interactive show

[Erik Rietman]

I'm currently exploring the possibilities of Qlab in an interactive show situation and I'm looking for the best setup for this:

• The basic idea is that we start the show with Qlab which triggers some music tracks and controls some light effects.
• The visitor of this show can play with some objects (like pushing a button or opening a cabinet which has a sensor in it) that have to trigger Qlab on playing other cues. Also with some light effects but probably also controlling a fog machine and some servo motors. 
• We also want to be able to interrupt the show and cue Qlab manually with an external controller (like launchpad for example.) for cueing 'special' cues.

Can anyone help me with the best approach for this? Is Qlab the right software for this? I also am thinking about Lanbox LCX for controlling stuf. But maybe there is a better way. I'm also trying to figure out what protocol to use (midi, msc, OSC etc.). 

I appreciate your help!

QLab would be a very strong candidate to do this for you.

I've done quite a bit of work in the last year with a RaspberryPi connected to force sensors, light sensors, etc. I've then written python code to command QLab via OSC. It's a lot of fun.

The more complex you create the Start / Stop sequences, the easier it is to fail (i.e. In my first version, someone stepping on / off a touch pad too quickly made the system fail). As long as you consider the odd exceptions, you'll be fine. I also programmed a TouchOSC system on my phone to execute special cues or restart the system. I would cue these from the outskirts of the crowd where we setup the installation.

Thank Drew for your input. I'm not a regular programmer for this kind of stuff but I'll look into it.

I'm planning on writing a blog post about this in the near future.

If you're really interested, holler, and I can write up a first draft (with code attached)

The RaspberryPi (and Arduino) is supposed to be really DIY. There's a bit of a learning curve, but it's approachable and affordable.

I'm interested, I'm willing to learn so help is welcome...:-)

Thanks Mic, good links!

I wrote this a while ago now, although it doesn't talk about using sensors etc to trigger cues, it's a good start with the basics of how QLab, OSC and Python work together.
