E4L LED Parameter Control
The E4L LED Parameter Control devices enables tight coupling and automation of lighting effects between Ableton Live and the EnvelopLX application.
Eight virtual controls are provided: P1 - P8. Like any other control within Ableton Live, these controls are MIDI mappable and may also be automated within session clips or the arrangement view.
For each of these controls, a text entry field specifies an OSC path that corresponds to the control. By default, these are mapped to the lighting channel faders. Any time the control is changed, an OSC message will be sent with the new value of the control. Buttons on the right can be used to manually re-send the current value of the control, even when it has not changed.
Nearly every parameter in EnvelopLX has a unique OSC path. These paths are self-documenting and easily discovering by simply moving your mouse over the control. The bottom status bar in the EnvelopLX will display the name of the parameter and a brief description of its function, followed by the OSC path. Simply enter this OSC path into the E4L LED Parameter Control and move the control.
Note: OSC paths in EnvelopLX are dynamic and often depend upon the ordering of your channels and patterns (for instance, parameters on channel 1 are all underneath /lx/channel/1/. If you re-order or remove channels and patterns, you will need to update the paths in the E4L LED Parameter Control.
At the bottom of the device the appropriate Host should be specified, matching the location and port of the EnvelopLX application.
Note: 0.0.0.0 in EnvelopLX corresponds to all addresses, and will receive messages sent to localhost when running both programs on a single machine.
