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.
