Speaker On button state detection

[johnclark]

Hi,
i'd like to know if it's possible to add "something" at the beginning of a song to detect if a specific track of that song is activated (i.e. to detect whether the speaker on button of that track is on or off). And if it's not, to automatically activate the track.
If it's possible, what would be this "something" ?
Thank you

Yep, you can observe a track's mute button state in M4L.

Ok thank you and before I buy the Max4live extension just for this purpose, can you confirm me that along with the capacity to observe the track's mute button state, I can change it with kind of a logical gate (i.e. if it's "off", i want it "on," if it's already "on", i'll let it stay that way).
That means M4L can let me execute kind of a little script at the beginning of a track. Is that so ?

Yes you can definitely do that !

I know it's too early to give you a patching advice, but I'll do it anyway :
You'll likely encounter an error message saying : "changes cannot be triggered by notifications" (which I plan to make as a T-Shirt by the way )
[deferlow] will then be your friend.

But more seriously, get back here, I'll be happy to help you to patch this little device (and it's a great first project to learn).

thank you very much for your help !

Ok i'm ready to go. I've just bought M4L. I've opened some tutorials like this one (https://www.youtube.com/watch?v=-eoToUb ... el=Ableton). It seems like what I want to learn is "controlling live" with M4L. But I have to admit that I don't know where to start.

The concept of my device is simple :
1) I have to check the state of the mute button of a specific track at the begining of my song.
2) if it's off, I want it on, if it's on, I don't want to change anything.
3) when my song is playing, the mute button is desactivated by other actions
4) when the song has ended. I'm playing another song in the same project and we're back to step one.

First, how can I check the state of a mute button ?

Get the id of a specific track by sending the message "path live_set tracks 0" (in this case the first track) to [live.path].
Or if you want the id of the track the Max device is on, use "path this_device canonical_parent" as shown in the video.

Send the track id and the message "get mute" and "get muted_via_solo" to a [live.object].

Or when you want to observe it, send the track id and the message "property mute" to [live.observer].


If you have a Max patch you want us to look at because you are stuck, select everything in the Max patch, go to the Edit menu, and select 'Copy Compressed'. hen you can paste the result here.
Such compressed code can be copied and simply pasted in a Max window as you would paste any text. It will automatically convert to objects etc.

I made a small example to get you going

Code: Select all

[johnclark]

thank you that's exactly what I was looking for to start with M4L. I'll check this by myself and let you know how it's going on.
