OSC

Overview

Open Sound Control allows you to send musical data over a network. You simply select the IP address and port of your receiving device. See our OSC Quickstart for a brief walkthrough.

OSC is a highly flexible protocol, which allows you to send any number of strings, floating-point numbers, or integers in the same message.

iOS Permissions

On iOS, Syntien 2 needs permission to access the local network in order to send OSC messages. You should see this prompt when you open the app. If you previously denied permission, you can enable it in your iOS Settings under Syntien 2 > Local Network.

UDP and TCP

Syntien allows you to send OSC via UDP or TCP. UDP is generally much faster, but there's not a guarantee that the data packets you send will arrive in order. Still, it's ideal sending for high-frequency, real-time data. TCP does a "hand shake" with the receiver and avoids the issue of packet loss, but does add a considerable amount of latency. TCP may be a better fit for data sent at a lower frequency, such as triggering lighting cues in a show via a control like the

Button or

Stepper.
