slider to adjust velocity of any midi out lemur

[eross21]

I have a drum kit template set up in lemur. I can finger drum Midi notes out of Lemur to drum apps, it works great. However, they are all at max velocity. I want to put a single fader all alongside of my drum pads in Lemur. All I want it to do is to adjust the velocity of and midi note coming out of Lemur. How can I do this?
