Panning Machines
Panning machines for stereo effects works exactly the same as changing, recording, or scripting the amplification of machines. The main differences are that panning may only be done on effects (or machines connected directly to the Master), Panning is accomplished by clicking and dragging the horizontal bar that appears only when effects are connected to a destination machine (another effect or master).

Stereo Effects: Although generators do not have pan bars on them, you could easily achieve stereo panning by simply adding a generic machine (Gains work well and serve obvious double purposes), and use the stereo panner on the effect.
