In the fast-paced world of presentations and entertainment, timing is everything. Yet, integrating show control software with traditional timer equipment has long been a challenge. Enter OSC Timer—a powerful, customizable solution designed to seamlessly bridge this gap.

The app’s versatility allows for multiple timers to run simultaneously, display system time, and even send OSC messages triggered at user-defined intervals. Enhanced Broadcast Features: Broadcast time, warnings, or custom messages across your network with ease. OSC Timer can subscribe to or unsubscribe from specific OSC messages, ensuring precise communication throughout your show. Dynamic Layout & Display: Arrange your timer display to suit your event’s needs—whether it’s a single timer dominating the screen or a multi-slot layout showing different timers, broadcasts, or even a system clock. The display is fully flexible, allowing you to tailor it perfectly to your requirements. Extensive OSC API: Explore the full potential of OSC Timer with an extensive OSC API that lets you manipulate everything from font size and alignment to background colors and border styles.

Absolutely endless amounts of uses if you use OSC. Timers are all set up and controlled using OSC. If you don’t use OSC then take a look at apps like TouchOSC that will allow you make custom a remote control for this app. If you want full details of all the parameters go to the developers website. Lots of control. Just send OSC to ports: 53001 for timer 1 53002 for timer 2 53003 for timer 3 53004 for timer 4 ## Frequently asked questions about OSC Timer ### What is OSC Timer?
