I have two dynamic streams of data going forwards and backwards.

I'm wondering if there is any way dynamically that I can filter the backward stream based on the ID, if the forward stream for the same ID is currently active? I realise it's possible to filter each one manually, using router objects etc. However you have to set these up for every stream coming through. I'm wondering if there is a way to do it dynamically.

e.g. (1st number is ID, 2nd number is float)

I want to compare the ID's and then filter the backward stream, if they match.

So, in this case, I would only receive backward stream messages.

In the following case, both would get through (nothing filtered because the IDs are not matching)

I'm wondering is there any clever way to do this in javascript, like some gating, which waits 1 millisecond if the forward stream is currently being sent?

Ive tried this in Max, but it seems not fast enough to catch all the concurrent streams:

And also Javascript, I was thinking maybe even something as simple as the following would work, but no dice as of yet.

outlets = 2;
inlets = 2;

function list(a){
var inny;
var innyd;
var outy;
var outyd;

    var a = arrayfromargs(arguments);

    if (inlet == 0){

        inny = a[0];
        innyd = a[1];
    
    }else{
        
        outy = a[0];
        outyd = a[1];

    }
    
    if(inny == outy){
    outlet(0, inny, innyd);
    
    }else{

    outlet(1, outy, outyd);
    
    }
    

}


Forward Stream:
1 0.43534
2 0.96872
3 0.92883

Backward Stream:
1 0.89382
2 0.28932
3 0.83498

outlets = 2;
inlets = 2;

function list(a){
var inny;
var innyd;
var outy;
var outyd;

	var a = arrayfromargs(arguments);

	if (inlet == 0){

		inny = a[0];
		innyd = a[1];
	
	}else{
		
		outy = a[0];
		outyd = a[1];

	}
	
	if(inny == outy){
	outlet(0, inny, innyd);
	
	}else{

	outlet(1, outy, outyd);
	
	}
	

}

if your Forward Stream has the highest priority , and it could be used to control all the data flow then u can queue Backward Streams into some sort of stack for later comparison .

For the further help there should be more info provided , like what conditions occur and when . how this feedback actually is designed .

Thanks for the info. Yes forward stream has highest priority. I haven't heard of using a stack of backward streams before for comparison. Are there any examples online that can detail this? I've been looking at FIFO streams to try and resolve this, but not sure exactly how I could use a queue in Max.

It's for a touchscreen/computer setup, so the touchscreen is the high priority item. However, it's nice to get feedback onto the touchscreen, when something is changed on the computer. It's pretty straight forward really. I've got a bunch of parameter IDs that are changing floats. These are going both in and out at the same time. However, they're conflicting together so:

2) Sometimes parameters will get mixed up (the data for parameter ID 5 may change the data for parameter 4 etc).

I'm not sure what else I could provide in terms of further info. Any thoughts would be much appreciated.

1) The parameters will become jumpy
2) Sometimes parameters will get mixed up (the data for parameter ID 5 may change the data for parameter 4 etc).

do you get z values from the touchscreen?

What I do in lemur sometimes is gate, using "/fader/z 1." as the toggle to turn *off* the stream back to Lemur.

right now I've just finished a really simple thing that lets me handle the back-n-forth without getting feedback issues. The rest I leave up to the performer.

I'm afraid most of the controls don't have a z control (up down). Would be great if they had z controls.
