| Beam FX Index/Speed | Effect Library | MSpeed | Shutter |
| Camera IR Image | Enable | Negative | Shutter Strobe |
| Clip Directory | File | Object Directory | Strobe Mechanism |
| Color Effect | File Type | Object File | Sync Source |
| Color Index | Front/Rear Projection | Output Command | Text |
| Color Mix | Generator | Page | Texture |
| Control | Generic Control | Position Blink | Timeline |
| Copy Mod | Image Movement Speed | Projector Input | Timeline Position |
| Cue | Internal Media Frame | Relay | Tracking Object |
| Dimmer Curve | Library | Select | Transition Speed |
| Edge Blend Profile | Macro | Shape | Transition Time |
| Effect File | Mode | Shape Library | Transition Type |
In the [About] channel patch screen, the snap column shows which parameters for that channel are currently set to snap. These parameters can be edited for any profile using the Fixture Editor. See Fixture Editor
