LEMUR
Design your own MIDI/OSC Controller
For over two decades, Lemur has defined the industry standard for transforming your mobile device into a customizable MIDI/OSC control surface.
Pioneering multitouch technology, Lemur has become synonymous with innovation in music performance and production. Its pivotal role in the evolution of music technology has made it the trusted choice of artists like Daft Punk, Björk, Plastikman, CHVRCHES, The Glitch Mob, Orbital, and many more.
In the film studio, Lemur has become a beloved tool for professional music composers, serving as the central hub for composing templates—managing sample libraries, keyswitches, mix automations, and DAW key commands.
With its intuitive interface builder and powerful scripting language, Lemur empowers you to create and share any controller you wish. From electronic music, to orchestral film scoring, to live sound, and professional lighting, if you can dream it, Lemur can build it. Lemur has even been used to make games!

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.
