ofxTLVMMControl is an addon for ofxTimeline to add a pseudo-track ofxDatGui channel full of widgets meant send params to my application VMM.

This addon is a customization of the ofxTLButtons addon by https://github.com/hvfrancesco/ofxTLButtons.

MyAddon uses ofxDatGui instead of ofxUI. I will publish a ofxTLDatGuiTrack addon for general purpose.

To use it with ofxTimeline basically you have to:

Add in addons.make after ofxTimeline and its dependencies add:

ofxTLVMMControl
ofxDatGui

-- or --

Use the Project Generator to add ofxTLVMMControl

In you header file add (usually next to #include "ofxTimeline.h"):

include "ofxTLVMMControl.h"

And the in your cpp file you can add buttons track with something like this:

ofxTLVMMControl* buttonsTrack = new ofxTLVMMControl(string osc_target_ip ,int osc_target_port);
string buttonsTrackName = _name;  //name of your track
buttonsTrack->setXMLFileName(buttonsTrackName+".xml");	//make sure to set the xml so it will save.
timeline->addTrack(_name, buttonsTrack);

To send events I created an event in the .h

//CREATES A PREPACKAGED OSC MSG EVENT.
class VMMOscMessageEvent : public ofEventArgs{
public:
    ofxOscMessage m;
    string message;
    int value;
  
    void composeOscMsg(int track, string msg, float val){
        message = "/" + msg;
        value = (int)floor(val);
        
        //compose an osc message
        m.clear();
        m.setAddress(message);
        m.addIntArg(track);
        m.addIntArg(value);
    }
    
    static ofEvent <VMMOscMessageEvent> events;
};

And then in the .cpp file add the instance of the event.

#include "ofxTLVMMControl.h"
#include "ofxTimeline.h"

// setup the events to pass back
ofEvent <VMMOscMessageEvent> VMMOscMessageEvent::events; 

Another importan note: If you want to disable the mouse events on ofxDatGui components the update() functions accepts a boolean param. Setting to false disables mouse events. This is needed if you have multiple timelines/tabs.

playNoteOffToggle->setPosition(bounds.getX(), bounds.getY());
playNoteOffToggle->setVisible(bounds.getBottom()-bounds.getTop() < playNoteOffToggle->getHeight() ? false : true);
playNoteOffToggle->update(guiAcceptEvents);

• TODO:
• • default settings when you create a VMM track
• • color coded VMMTLControl sliders for easy identification
• • reduce the height of the params. adopt style of enclosing UI
• • color code clip matrix so you know which clip has data
• • *button to reset params.
• • test button.
• • clear button.
• • disable frame I-bar with VMM track.
• • setup undo on VMM
• • tab navigate through VMM controls
• • step increment on VMM params.
• • custom curve track with controls on the left and right.
• • Hide measure bars on VMM track only if VMM track is present.
• • alternate colors for bars in background
• • *render button
• • change params to float.
• • reload/revert track.
