Open Sound Control

Open Sound Control (OSC) was created as a successor to the MIDI control protocol. It enables communication between computer software, sound synthesizers and other multimedia devices that support OSC.

Its advantages over MIDI include: an open-ended and dynamic URL-style symbolic naming scheme, symbolic and high-resolution numeric argument data, pattern matching language to specify multiple recipients of a single message, high resolution time tags and "bundles" of messages whose effects must occur simultaneously. The protocol is also not bound by specific hardware (i.e. MIDI cables and ports) and can be transferred across any network connection, even remotely via the internet.

This makes OSC much more powerful than MIDI, but due to its open-ended specification, both the OSC client (which sends OSC data) and the OSC server (which receives data, i.e. Renoise) must be separately configured, unlike MIDI which is essentially "Plug & Play".

For more general information about OSC, see the OSC Wikipedia page and the official OSC homepage.


Setup

Renoise can use OSC in one of two ways:

  1. Using Renoise as an OSC server (OSC receiver) via a preconfigured OSC message set.
  2. Using the fully configurable and customisable Renoise scripting API. This allows you to send and receive any form of OSC message and define your own communication protocol, but obviously requires programming knowledge.


To set up Renoise as an OSC server, open the OSC options panel by choosing "Edit -> Preferences -> OSC" from the main menu:

  • Enable Server: This starts the Renoise OSC server and the network port is changed to a listening state, so you may get a firewall warning the first time this is enabled.
  • Incoming Messages: This panel simply displays messages relevant to the networking process.
  • Protocol: Select the protocol which the Renoise server will use:
    • Udp: Provides a high transfer rate with lower reliability than Tcp.
    • Tcp: Provides a lower transfer rate than Udp with higher reliability.
  • Port: Select the Port number for messages to be transferred over. Generally, a number greater than 1024 is used.
  • Command List: Lists the various commands that it is possible to use to communicate with Renoise.
  • Explanation Panel: When clicking on a command in the Command List, an explanation of what the command does is displayed here.

Note that the default OSC implementation can be extended by editing the file "GlobalOscActions.lua" in the "Scripts" folder, found within the directory where you installed Renoise (on OSX this is found in the app bundle).


Examples

TouchOSC via Duplex

The Duplex Tool comes with a Device preset for TouchOSC, an iPhone / iPod Touch / iPad app, that allows those devices to control Renoise via OSC. To use it, select "TouchOSC" from the "Device" pulldown menu in the Duplex Browser and adjust the configuration as needed within the "Settings" dialog box. Then, using the TouchOSC app on the Apple device, you can change the values of the various knobs and sliders on the screen to control various features of Renoise.

Duplex uses Renoises Scripting API to communicate with touch OSC, so its fully configurable, and can also be used as an example on how to wrap up your own OSC implementation in Renoise.

Pure Data

PD (aka Pure Data) is a real-time graphical programming environment for audio, video, and graphical processing. PD was created to explore ideas of how to further refine the Max paradigm with the core ideas of allowing data to be treated in a more open-ended way and opening it up to applications outside of audio and MIDI, such as graphics and video. There are different versions available to download for PC, Mac and Linux.

Using PD With Renoise Via OSC

  • First install PD, then download, unzip and open the "test-renoise-osc.pd" file within PD.
  • In the top left corner you can set the port number to match the OSC port number you have chosen for Renoise [connect localhost XXXX]. With Edit Mode (Ctrl + E) you can edit the numbers.
  • To the right, you can start and stop playing Renoise with the [send / renoise / transport / start] and [send / renoise / transport / stop] buttons.
  • The test program comes with a set of commands already loaded in. Make sure a sample is loaded into into slot 00 within Renoise and press the "chord-test" button in PD. You should hear a chord being played. You can also click on the individual commands to hear the individual notes.
  • If you would like to enter new OSC messages yourself:
    • Select from the menu "Put -> Message", place the box on the screen and enter your desired command (check the OSC Command List for available commands).
    • Connect the new message box by hovering over the bottom left corner (the cursor will become a circle) then clicking and dragging over to the "sendOSC" box.
    • Cancel edit mode with (Ctrl + E) and click the box to send the message to Renoise via OSC.
