Reactive Programming Paradigms
Build Dynamic UIs
Lemur’s powerful scripting engine allows you to bind controls to each other, creating responsive, dynamic interfaces that update in real time.
This flexibility makes it easy to propagate changes throughout your UI, enabling powerful, interactive mobile experiences.
Add Time-Based Effects
Bind scripts to clock time to create pulsing, rhythmic patterns, animations, and periodic effects.
Sync to MIDI Clock
Lemur’s built-in sequencer widgets—StepNote, StepSwitch, and StepSlider—make it easy to create step sequencers that synchronize to an external MIDI clock with high timing accuracy.
With clock-synced scripts, you can transform Lemur into a powerful sequencer UI for controlling live sets, beat production, loops, and rhythmic patterns.
Frame-Driven Event Loops
Bind to the frame rate to create event loops, enabling game programming paradigms that evaluate, update, and display in real time.
