Open Sound Control (OSC)

9.1.1. What is OSC

Open Sound Control (OSC) is a modern network-based communication protocol that can be used to
send a variety of control messages between OSC enabled devices. OSC input is supported on every
product in the LAMPY series.
OSC enables you to use OSC enabled controllers such as a synthesizer, electronic music instruments,
production audio software, and mobile phone apps such as Touch OSC to remotely control your
console.

9.1.2. OSC via Wireless LAN

Sending and receiving OSC over Wi-Fi is supported using 3rd party wireless routers, however, we do not
recommend using OSC over Wi-Fi for show-critical tasks for several reasons:
● Reliability: OSC uses UDP (User Datagram Protocol), which does not include error-checking. This
means that the LAMPY cannot verify that OSC messages sent by the console will be received by
mobile clients and vice-versa.
● Interference: Wireless routers that operate in the 2.4 GHz radio spectrum are subject to large
amounts of interference due to the popularity of the 2.4 GHz radio band for consumer-grade wireless
devices.
So if you have a lot of people attending your show, your Wi-Fi may or may not work properly, or the
speed might slow down.

9.1.3. How to Setup OSC

For information on how to setup OSC, please see section 8.5.2.8. Enabling the Open Sound Control (OSC)
