Possible to have on screen elements output values to midi in port?

[CalenShirfield]

I want to create a web based midi controller that can send cc values to a device. Currently, I have a slider that updates it’s position when receiving rawValue from addlistener(‘controlchange’).
I also have an addEventListener(‘input’) on slider. I want my device to receive this slider value as a cc event on input.

To do that, you can simply use the sendControlChange() method of either the Output or the OutputChannel objects. Did you check the documentation? It has an example that's pretty close to what you want to do in the Sending Outgoing MIDI Messages section.

Thanks djipco.I have hooked up Snoize midi monitor and In order to see the cc's there is an option to spy on output to destinations. I can see they are arriving with the slider value adjustments. However with a launchpad device there are further requirements to get LED feedback. This threw me. Thanks again.
