Maxmsp to control lights, video and sound?

starlet_0808's icon

Hi all

I have done a couple of simple projects with Maxmsp before but would like to ask if it is possible for Maxmsp to control lights, videos and sounds using a series of sensors for an interactive film installation, and would using the Teabox be the best way to go about this?

Thank you very much for your time and help.

Joyce Chin.

yes it can

now, i don't know Teabox, but i did a lot of sound-things with msp, video with jitter (and softVNS as well) and lights with the help of a lanbox. And used different sensors as well

so yes

Yep, I use Arduino, serial input, or just plain MIDI from my sensors, I also use a Lanbox to send DMX to my lights, and obviously you can set up triggers for different audio or video events. I haven't heard of Teabox before, but looks expensive considering what you could do fairly cheaply with an Arduino, a few sensors and some limited electronics (Arduino playground web page is full of basc tutorials and step by step guides). But, if you are short of time, have never done any soldering, and want something tidy then may suit. Also depends what sensors you are using and what resolution/speed you want your input in as to how simple a setup you need.

It doesn't look like Teabox will help you to control lights though, you'd still need either a DMX light solution or, to control non DMX lights, maybe a simple(ish) circuit involving a relay or a transistor used as a switch or even something more complicated and clever!

Thank you all. I shall check out the Arduino. Problem is I've never used it before so might struggle with it quite abit. May I ask what is a lanbox and where can I get one?

I too am looking for a simple DMX interface to use with Max and hopefully with Max for Live. I currently am using a Chauvet Obey 40 but this only lets me send MIDI notes that change the static lighting state of my lights (2x Chauvet Colorbank LEDs, 2x Chauvet LED Shadows and 1 Triphase LED).

The lanbox seems to only have the 5 pin DMX connections, but my lights use standard XLR cables to transmit the DMX signal. Is there not a simple USB interface with standard XLR outputs that transmits DMX and is compatible with Max/MSP running on my OSX 10.5 laptop? Also, the lanbox looks like a tank, isn't there something smaller?

Also, has anyone used one of these cables?

Do they work with Max?

You can get a lead to convert a five pin to 3 pin no problem.

I love tanks.

I wish...anyone? Windows too?

I have purchased my Arduino Uno and some light sensors to play with. Only managed to get the Arduino to talk to Max using Maxuino so far. Hope it goes further than this in the next few weeks! =)

Have you looked at this?

I have used the latter extensively and it's quite solid. You will need to adapt from 5pin to 3pin, but as has been said this is quite easy to find.

The DMX USB Pro has a native Max object that has been developed by Olaf Matthes:

Hi everyone.

I kinda need help tackling a problem. Here's my patch so far. Basically assembled a few patches to create this as I can't programme from scratch. How the project works is, there are different photocell sensors in different boxes, and as you open a different box it would play a different movie. The problem is in between the movies, I would like to play certain audio files. I can't rationalize this in terms of programming. Can anyone suggest an idea of how I might go around doing this?

Max Patch
Copy patch and select New From Clipboard in Max.

For best help on the forum I'd start a new thread with this as the original question was kind of answered, also (and this will help you learn) I'd try cutting out the bits of the patch that you don't need and get just down to the essentials for what you are trying to do before you post, then its easier for people to help you.

Saying this, I see you are using a value to send a bang to the 'stop' message for your movie, couldn't you also use that bang to hit the '1' message going into [sfplay~] and play your sound file? If you want it to loop then send 'loop 1' message to sfplay on a loadbang.

Hello,

seejayjamesthere, there is a simple USB interface with standard XLR outputs that transmits DMX, it's the bus powered USB-DMX interface from Michaêl Egger

It comes with all the externals for Max. It's the smallest interface To DMX i've seen working and very well. You can buy the stuff or DIY. Michaël give all the references.

I've got the usbDMXpro from Entecc with Olaff Mathews object and work perfectly for three years in many different theaters.

Cheers

@franck: that is cool and I'd seen it before, but good to be reminded. Love the small size and plug-and-play capability.

Still I would love an included C74 external (cross-platform) which takes lists in (512 channels of 0-255 data) and does the formatting to send to [serial], you could pick Art-Net or OpenDMX protocol.

OK, yes, I want someone else to do the dirty work... :/

Hi scatalogic

Thank you for your reply. I shall try that. =)
