Serial to Midi?

Is anybody doing any serial to midi projects? I have a simple program called hairless midi that does just that. I am trying to use it in conjunction with my Arduino Mega and a few potentiometers. My goal is simple, turn a potentiometer and it controls a function in a VST or DAW (like a volume fader or the cutoff knob of a filter). I can’t seem to figure out the appropriate steps though. Has anybody done anything like this?

Never done anything like that... but if you're trying to figure out how to use potentiometers with your Mega, you would essentially build a variable voltage divider and connect the output to an analog input of your mega.

If you already know all of that, then I don't know enough about MIDI stuff to answer your question!
