How do I map a continuous controller in relative mode?

@rank13, @David-san: thank you, that is encouraging. As requested, below is a screenshot of what my controller is sending now. I built my MIDI controller using a Teensy Arduino board, so can program it to do send whatever I want. Currently the encoders (16 of them) are sending relative values of 66-70 for increment, and 2-6 for decrement. (The different values are related to how fast I am turning the knob. However, I am not concerned with dealing with rotary speed for now; a simple increment and decrement is all I need.) Any tips on scripts would be helpful. I’m still coming up to speed on setting up my rackspaces! Gig Performer is an incredible piece of software; its going to completely change my live gig setup.
