How do I receive audio from multiple tracks?

[deHaan]

Hi there

Probably a very basic question:

How do I get input from other tracks than the track my max for live effect is on? Right now I'm using the "plugin~", which only takes the audio from that track...

Hope you can help me

Best regards Nikolaj

No help from you guys?

Or is this impossible to do with M4L? I want to use different audio tracks for controlling different parameters in my Jitter patch...

[S4racen]

use sends to get the audio to your device sitting on a return track....

But then all the audio will be mixed together right? I want the signals as individual inputs in my patch. So that the audio signals can control different parameters on my video effects...

use separate patches, monitor the incoming audio then convert it into a value, then use a send object to route all those values to your main patch.

Ahaa great, that was what I was looking for Thank you!

Now I've been experimenting a little with patches using the "send"-object. But they tend to increase my CPU-use quite a lot. Any suggestions about how to avoid this?

I think CPU load depends on the rate at which you are sending values.
Try using a rate as low as possible. Packing multiple values into a list may help too.

Alternatively, you could use udpsend/udpreceive for transmitting data across devices.
It's probably more efficient regarding CPU load.

if you're monitoring an audio input, the snapshot~ object can specify a particular frequency of the sampling, if you don't need the high frequency then this can really cut down on the load. The other thing to do would be to bang the snapshot~ object when you need a sample, instead of having it continually spitting out values...
