Is there any way to get the value of the zoom display? I thought it would just be the zoom factor in max but its an independent thing, I'm wondering if anyone's been able to get it via LOM or something else?

I see from the LOM and other forum posts that it is possible to observe which scene is "selected". 

Is there a way to observe which scene has been "triggered" (or "fired" or "is playing")?

No.  But one pretty easy solution would be to take is a “dummy” track with no clips and to observe it’s fired slot index.  At least I think there is such a property and it should work…

How to observe "triggered" scene

I have reached stalemate in the project I am currently working on. The idea is to use a XBOX controller that will trigger notes. For that, I want to create a sort of instrument fingering (like a flute or oboe woud have to seal the holes) with the buttons on the right of the controller. This idea would correspond to use a kind of a """standard""" fingering for a digital instrument.

I figured that maybe it would be playable to set C on the A button, E on the X, G on the Y and B on the B (to make an arpeggio). To make the middle notes (D, F and A) I was wondering if it could be possible to assign them with multiple button pressed. To do so, A and X would trigger D, X and Y would trigger F & Y and B would trigger A.

I tried multiple stuff to achieve this idea, and the most convicing one was to use the [if] object. You can check the patch atached to this post to look at what I tried. 

1) why does the [sel 0 1] object coming from the X buttons bang the two outlet at the same time everytime I try to do a D ?

2) did I missed an object that would simplify what I'm trying to do ?

3) I have the strange feeling that everytime I am close to the answer, I missed something and everything seems to be nonsens afterall. Like I can finally press A and X to trigger D BUT the A triggers the C at the same time which leads to hear two notes at the same time... 

If someone has a clue that might help me solving this problem I'd be thankfull !! (please excuse my english, I'm a foreigner)

I'm trying to send notes to a vst instrument in Live via midiout. When I click to bang the kslider, the note triggers properly. However when I send bangs to the kslider via metro, no notes are played in Live. 

It works fine when I send notes via noteout, but noteout only works for the same track that the device is on. I want to be able to send notes to any instrument track.

I'm trying to create a shortcut that show the browser and select the "Current Project" place.

Using the LOM, I can focus the browser but I can't select the "Current Project".

In the older LiveAPI 11, I think that live.app had a browser property, but is missing in the 12.

Anyone knows a way to access to the "Browser" class.

Please someone take a look. I never noticed this before. A very simple js to observe the "mute" button state of a track. Add device to multiple tracks, everything works as expected, mute state is printed to Max window. Now as soon as one of the devices is deleted, all other js observers stop working. I even tested it with 2 different devices observing different path and property, they break each other when one is deleted.

mute_js_fr.amxd

JS is frozen into it and looks like this:

    var obj = new LiveAPI(callback,"live_set this_device canonical_parent");

        post(obj.path, args, "\n")

The same thing with Max object works as expected. Is there something wrong with the JS? How can removing one break another one in a completely different device and js?

js-observers-stop-working-if-another-devicejs-with-observer-is-removed-from-the-set

I can reproduce in both Live 11 and Live 10 (using 10.1.41, with whatever Max is bundled).   I thought there might be something funny with the scoping in the callback, but then I wrote the code like this and get the same result:

function bang ()
{
	var obj = new LiveAPI(function(args) {
		post("mute2", this.path, args, "\n") 
	} ,"live_set this_device canonical_parent");
	obj.property = "mute"
}

The below works fine -- the observers are appropriately isolated in their scope.  But it does nothing to explain how the function-scoped variable initialization you use gets graduated into a global scope...

var obj = null
function bang ()
{
	obj = new LiveAPI(function(args) {
		post("mute2", this.path, args, "\n") 
	} ,"live_set this_device canonical_parent");
	obj.property = "mute"
}
This is closer to how I do my observers (though often its in an array of observers or encapsulated in some other object.)  

I guess really my intuition is that the observer initialized in your original bang() ought to cease to exist after it's function scope since it's not explicitly retained elsewhere.  Then the fact that your code worked in the first place would've been a memory bug in Live.


Interessting, I have not seen it written like that. So instead of a function name I can write the callback directly into the LiveAPI( parameters)? I followed this doc . And 

Technical note: you cannot use the LiveAPI object in JavaScript global code.

doesn't sound like I have to retain the obj in global scope. Further when you look at the example at the bottom of this page it looks like it's the recommended way to put the callback into the function scope.
btw: support just confirmed it as a bug

I really lost some hair today trying to find the mistake.
 🦲 

I always took "you cannot use the LiveAPI object in JavaScript global code" to be about the initialization and function calls where writing them directly into the global code would imply you're trying to do things before [live.thisdevice] has notified that the Live API is ready.  For instance in the example code at the end of the page I would expect that code could only be happy living inside another function call (as in your bang() ), and that's sort of backed up by them having a 'return' statement in there.

As for the inline syntax format: I don't normally do that, either, as it's hard to read.  (It also comes with an  issue where it triggers with "id nn" before you've assigned the property name you want to observe).  It was just for me to test because I thought having a functional reference to 'obj' inside the callback was maybe a little questionable as I assumed the callback() would go away outside of your bang() scope. **

And now if it's confirmed as a bug -- and I assume you mean that your initial code should work and persist observers as written -- I guess I'm also surprised the implied behavior is that once you instantiate an observer it stays alive indefinitely.  Seems like that would be bad for memory/performance.  I normally track observer lifespan and aggressively try to unassign their observed property and null them out when they are no longer needed.

** I didn't intend to confound the two differences (inline callback AND variable outside of function) in the second example.  Sorry!

Yes it makes sense to track the lifespan. I had a few situations today where it seems like callbacks were called from memory so that I had 3 messages from one api object. But that may also be caused by opening and closing the editor. Anyways I'm waiting for the fix. Thanks for looking at it Tyler!

Is there something like free(obj) in js? Setting obj.property ="" doesn't feel like obj will be garbage collected. But the global scope will help to reuse it without creating new LiveApis all the time. I can see that!

there is for... only jitter objects:
myJitterObject.freepeer();

I think I just borrowed that obj.property = "" practice from elsewhere in this forum.  For some reason in my Favorites list is now marked as spam!:


In effect what I've been doing (maybe without satisfactorily answering your question for all JS) has been:

obj.property = ""
obj = null

And it seems to work... certainly no more redundant callbacks getting fired for me?

I would love to see an official JS LiveAPI best practices guide.  There is a decent amount of not-very-intuitive stuff that goes on, IMHO.

To conclude here and for future reference: Putting the obj variable in global scope seems logical and fixes the problem of my first post. I'm no longer convinced it's a real bug, maybe just some confusing example code in the live js documentation.

var obj;
function bang ()
{
	obj = new LiveAPI(callback,"live_set this_device canonical_parent");
        obj.property = "mute";
        
 	function callback(args) 
	{
  		post(this.path, args, "\n");
	}
}

I'm trying to figure out how to loop a sequence of samples (Round Robin) playing a single MIDI drum pad repeatedly.

I also need to be able to reset the sequence via another Drum Pad (MIDI mapped) so next time I hit the other pad the sequence starts on the first sample again.

So far, I found 3 different methods of achieving that effect (almost) in Ableton:

Problem: none of these methods allow to reset the sequence via MIDI mapping.

Unfortunately I don't know Max4Live, to fix this myself.

Maybe  someone here  can help me achieve the desired effect :)

I'm looking for a device in Max for Live that can duplicate the length of a currently selected MIDI clip. Let's say you've recorded a 1-bar bassline but want to extend it to 2 bars to add some automation over the last few beats. Ableton Live has a button for this, but I need a simple device for my live performances.

I'm a beginner with Max for Live, but I'm willing to give it a shot if nobody has created this device yet. Any tips would be greatly appreciated!

I'm new to M4L and doing a computer science project for school. I will need audio clips of each preset (.adg) for Analog. Basically, this is for ML purposes so I need some good training data.

Load Presets: Automatically load each preset into the Analog synth. 

Listen to a loop: Set a loop within Live with MIDI clip inside of it. For now, I'll just play a single C note but would also like to record a progression later on.

Record the Output: Start and stop recording to capture the audio from the synth. 

Save and Label the Recording: Each recording is saved with an appropriate label that matches the preset for easy identification.

So far I haven't had any luck with anything. I can't seem to even access the device using live.path and live.object.

Just wondering about the complexity of this task.  I've watched the tutorials and played around with it but any of the things I've listed above I can't figure out. I'm also not sure how I would iterate through each preset? What do you guys think?

so about three years ago i found someone on this forum to write a custom m4l device for me:

https://cycling74.com/forums/uimacro-for-creating-new-tracks-and-assigning-input-channels

sadly, it stopped working after the new Live 12 update, and i can't get a hold of the person who originally made it for me, Patrick_K.

So - is there anybody willing to have a look at this for me?

The devices input lists are still beeing populated according to my hardware, but when i "Add" a track, nothing happens.
