Filmstrip knob value display

[RalfsPlucis]

Hi all,

I know this has been covered before, but I could not make any sense from previous posts. I am trying to pull out values from filmstrip knobs and display them on a label. However, it does not seem to connect. I tried to customise similar code posted before and adapt it to my needs. I would appreciate if someone could take a look and provide some guidance, as my coding skills are far from from good. :D Also, i would like to know how to display time values from delay speed (e.g. 1/4, 1/2 etc.). Please see below the code, and see if you could help with it. Much appreciated. :)

// [/JSON Knob]
const var ReverbRoomSize = Content.addKnob("ReverbRoomSize", 558, 58);
// [JSON Knob]
Content.setPropertiesFromJSON("ReverbRoomSize", {
  "text": "ReverbRoomSize",
  "width": 56,
  "height": 57,
  "min": 0, 
  "max": 1, 
  "stepSize": 0.01,
  "processorId": "Reverb 12",
  "parameterId": "RoomSize",
  "filmstripImage": "{PROJECT_FOLDER}SmallKnob128frames.png",
  "numStrips": "128"
});
// [/JSON Knob]

inline function onReverbRoomSizeControl(component, value)
{
	Label.set("text", ReverbRoomSize.getValue());
};
ReverbRoomSize.setControlCallback(onReverbRoomSizeControl);

const var Label = Content.addLabel("Label", 30, 50);
// [JSON Label]
Content.setPropertiesFromJSON("Label", {
  "editable": false,
  "saveInPreset": false
});
// [/JSON Label]

Hi,

the code you posted works, but it's ugly:

1. Don't use these autogenerated JSON blobs. They are so 2017 :)
2. You need to somehow process the raw value, or it will look ugly on the label. The function Engine.doubleToString() was added for exact this purpose.
3. Did you check out the value popup feature? It does something similar and requires no coding plus it shows the correct value including suffixes and tempo names.

Thanks, @Christoph-Hart for your reply.

As i mentioned before, I am new to all this. :) I managed to make it work, it now connects to the FX module and displays number values. But what if i would want to display TimeSync values, such as 1/4, 1/2, 1/8 etc? This is the code I ended up with:

//
const var room = Content.addKnob("room", 558, 58);

// [/JSON room]
Content.setPropertiesFromJSON("room", {
  "text": "RevRoom",
  "width": 56,
  "height": 57,
  "min": 0,
  "max": 1,
  "filmstripImage": "{PROJECT_FOLDER}SmallKnob128frames.png",
  "numStrips": "128"
});
// [/JSON room]

const var Reverb = Synth.getEffect("Reverb 12");

inline function onroomControl(component, value)
{
	local v = Engine.doubleToString(value, 2); 
	Reverb.setAttribute(Reverb.RoomSize, value);
	roomLabel.set("text", v);
};

room.setControlCallback(onroomControl);

const var roomLabel = Content.addLabel("roomLabel", 28, 105);

// [JSON roomLabel]
Content.setPropertiesFromJSON("roomLabel", {
  "saveInPreset": false,
  "editable": false,
  "multiline": false
});
// [/JSON roomLabel]

Worth mentioning that the TimeSync value that is displayed on a label would also have to change between ms and time signature values on "SynctoHost" button control.
