I have a DMX patch controlling a light fixture. I would like Max to read the volume of a track in Live and use that information to control the colour intensity of the light. This way the light will follow how loud the sound is from that track. I just need pointing in the right direction. Which object(s) do I need to use for Max to 'read' a track in Live? I can't use Soundflower for this as I need the sound to come out of Live and into my audio interface.

Do you have max for live? if so, you can set up an live.observer to monitor the output levels of the track in question and process the results from there.

If not you could use loop back if your sound card can handle it.

This should work straight out of the box.

It reads the incoming audio volume and also allows you to smooth the data out (kinda like the slide object)

I use it by putting it on a return track and then sending the audio to it. I also make sure that the sends in question are set to PRE instead of POST.

This allows you to easily send any amount of audio data to just one track.

Udpsend is used to send the data to max, the ip address is an internal one for your computer so just make a new max patch put in a UDPreceive object with the same port number (7001 with this one) connect its output to a float and then you know if its working.

If the signal isn't coming in loud enough then just add a utility to gain it and a compressor/limiter if you want to balance out the range.

Whoops, yes the above is a Max for live patch.

Andro, that is perfect for what I need. Thank you very much!
