LSS4's show event editor gives you precise control over how each scene behaves in the timeline. The phase editor controls speed and acceleration. The transparency editor creates smooth fade-in and fade-out transitions. Together, they turn a sequence of scenes into a polished, professional show.
Phase Editor
The Phase editor lets you define how a scene's animation plays during the event's duration in the show timeline. Instead of playing the scene at a fixed speed from start to finish, you can ramp up, slow down, or create complex speed curves — all within a single event.
This is particularly powerful for effects-heavy shows where you want the visual tempo of the lighting to match the energy of the music or performance. Accelerate into a drop, decelerate into a breakdown, hold steady during a verse. The phase editor gives you that choreographic control without needing separate scenes for each tempo.
Transparency Editor
The transparency editor controls the opacity of a scene event over time in the show timeline. A simple fade-in at the start and fade-out at the end makes scene transitions feel smooth and professional instead of abrupt. But you can also create complex transparency curves — gradually revealing a scene, holding at partial opacity for a layered look, or creating pulse effects.
When combined with multiple tracks in the timeline, overlapping events with different transparency curves create beautiful crossfade transitions between scenes. It's the same technique used in professional video editing — applied to your LED show.
Event Management
Each event in the show timeline represents a scene playing during a specific time window. Events can be added from the main menu, positioned by dragging, and resized by adjusting start/end handles. The event context menu gives you access to copy, paste, and duplicate operations for quickly building out complex show structures.

FAQ
What is the Phase editor in LSS4 and how does it work?
The Phase editor controls how fast a scene's animation plays during its time window in the show timeline. You define a speed curve: the scene can start slow and accelerate, play at constant speed, or decelerate toward the end. This lets you precisely control the visual tempo of each lighting event — matching the energy of the music without needing separate scene variations for different tempos.
How do I create smooth fade-in and fade-out transitions in an LED show?
Use the Transparency editor for each show event. You can define an opacity curve that starts at 0% (fully transparent), rises to 100% (fully visible), and returns to 0% at the end. When overlapping events use complementary transparency curves, you get smooth crossfades where one scene fades out as the next fades in.
