JS API : Calling get("volume") on a MixerDevice

[mdk]

If you do this :

Code: Select all

autowatch = 1;

var firstTrackMixer = new LiveAPI(this.patcher, null, ["live_set","tracks",0,"mixer_device"]);
post("FTM " + firstTrackMixer.children + "\n");
var volume = firstTrackMixer.get("volume");
post("Volume " + volume + "\n");
post("VolumeType " + volume.type + "\n");
post("VolumeInfo " + volume.info + "\n");

for(var i in volume) {
	post(i + " : " + volume[i] + "\n");
}

I get this output :

Code: Select all

js: FTM canonical_parent,panning,sends,volume
js: Volume id,1
js: VolumeType undefined
js: VolumeInfo undefined
js: 0 : id
js: 1 : 1

Which looks like im getting back an array containing [id,1].

Shouldnt it return the actual DeviceParameter object?

so i tried using it as an ID to create a new object :

Code: Select all

autowatch = 1;

var firstTrackMixer = new LiveAPI(this.patcher, null, ["live_set","tracks",0,"mixer_device"]);

var volumeID = firstTrackMixer.get("volume");
post("VolumeID : " + volumeID + "\n");
var volume = new LiveAPI(this.patcher, null, volumeID);

output :

Code: Select all

js: VolumeID : id,2
jsliveapi: set path: invalid path

so thats an invalid path, similarly just passing in a number as an ID fails :

Code: Select all

var test = new LiveAPI(this.patcher, null, 1);
for(var i in test) {
	post(i + " : " + test[i] + "\n");
}

invalid path again.

I've tried all the variations I can think of with using an ID : ["id","1"], "id:1", "id,1", 1, "1" etc.. and nothing works.

whats the magic incantation im missing?

[mdk]

im on a roll now..

why does asking for the path of an API object give you a string wrapped in quotes?

Code: Select all

autowatch = 1;

var firstTrackMixer = new LiveAPI(this.patcher, null, ["live_set","tracks",0,"mixer_device"]);

post("FTM Path : " + firstTrackMixer.path + "\n");

var volumePath = firstTrackMixer.path.substring(1,firstTrackMixer.path.length - 1) + " volume";
post("Volume Path : " + volumePath + "\n");
var volume = new LiveAPI(this.patcher, null, volumePath);
post("Volume " + volume + "\n");
post("VolumeType " + volume.type + "\n");

as you can see i can substring the bit i want, but thats not nice code

basically I want to find a way to navigate the LOM from parent to child, ideally without having to construct absolute paths each time.

Does this help?

Code: Select all

autowatch = 1;


function mixer_nav()

{
	var firstTrackMixer = new LiveAPI(this.patcher, null, ["live_set","tracks",0,"mixer_device"]);

	firstTrackMixer.goto("volume");
	post(firstTrackMixer.get("value"));
	firstTrackMixer.goto("up");
	post(firstTrackMixer.path);

}
