OSC (Open Sound Control)

grandMA3 ユーザマニュアル » リモート入出力 » OSC (Open Sound Control) Version 2.2

Open Sound Control, or OSC, is a client and server system that defines a message address pattern used to address elements in the receiving server. Open Sound Control allows devices of different types to control other devices via a peer-to-peer messaging protocol. OSC messages are human-readable, so they are more than just numbers and strings (unlike, for example, MIDI Show Control, or MSC).

The grandMA3 software supports OSC 1.1. For more general information about OSC, e.g. OSC Packets, see https://ccrma.stanford.edu/groups/osc/spec-1_0.html.

OSC Structure

OSC messages follow a specific pattern:

"(/prefix)/[OSC Address],[OSC Type],[Value]"

Prefix: This is optional, depending on your system setup. It can be used in a more complex OSC network to distinguish messages intended for one set of devices (e.g., lighting consoles) from others (e.g., sound consoles). If a prefix is specified, only OSC messages beginning with the specified prefix are processed, and the prefix is prepended to outgoing OSC messages.

ヒント
The prefix must not contain any slashes ("/").

OSC Address: This is the target you are controlling on the receiving device(s), for example /Fader201 would be the address to move the fader for executor 201 in grandMA3. Sometimes the address will be more complex, for example /Page1/Fader201 would be the address to move the fader for executor 201 on page 1 in grandMA3.

制限
Only OSC messages are supported when receiving or sending an OSC packet. OSC Bundle messages are currently not supported.

OSC Type: This is the type of value you're sending, for example:

i = integer

f = float

s = string

T = true

F = false

Value: This is the value you send to the target.

An example OSC command to set the fader for executor 201 to 100 might be:

  • "/Page1/Fader201,i,100"
  • or with a prefix to specify only, e.g. grandMA3 devices: "/gma3/Page1/Fader201,i,100"

OSC Menu

To open the OSC Menu:

  • Menu - In & Out - OSC.

The OSC Menu opens:

Open OSC Menu without any values.
OSC Menu

At the top of the menu, the following four options can be set:

  • Preferred IP: This is the preferred IP address or address range used by the OSC protocol.
  • Interface: Tap this button to open the Select Interface pop-up to select the desired network interface. For more information, see Interfaces and IP.
  • Enable Output: This toggle button must be enabled to transmit OSC. See Station Control in Network preferences for more information.
  • Enable Input: This toggle button must be enabled to receive OSC. See Station Control for more information.
ヒント
When receiving OSC messages, Enable Input will highlight its title bar in yellow. When sending OSC messages, the title bar of Enable Output will be highlighted.

The following are the specific parameters that can be set in the OSC menu:

  • Name: Sets the name for this configuration.
  • Destination IP: Sets the IP address for sending OSC data. A specific IP address or a broadcast IP can be set.
  • Tags: Opens the Tags editor.
  • Mode: OSC packets can be sent via UDP or TCP.
  • Port: Specifies the network port of the incoming and/or outgoing OSC packets.
  • Prefix: A prefix can be set by the user if he needs to. A prefix can be used for example as a criterion for limiting the range of possible receivers, e.g. /lighting would only take packets with /lighting into account, and discard OSC packets with the /sound-prefix.
  • Page: Specifies which OSC Address of incoming OSC messages is routed to pages.
  • Fader: Specifies which OSC Address of incoming OSC messages is routed to faders.
  • ExecutorKnob: Specifies which OSC Address of incoming OSC messages is routed to the mini encoders.
  • Key: Specifies which OSC Address of incoming OSC messages is routed to keys.
  • FaderRange: Specifies which OSC value range is used for the fader, e.g. FaderRange 255 sets OSC 0-255 to 100%.
  • Receive: Specifies if OSC data (but no commands) shall be received.
  • Send: Specifies if this OSC configuration sends OSC data (but no commands).
  • Receive Command: Specifies if commands for the command line will be received via OSC. This setting is independent of the general receive setting.
  • Send Command: Specifies if commands of the command line will be sent via OSC. This setting is independent of the general send setting.
  • EchoInput: Specifies if the input data shall be displayed in the system monitor.
  • EchoOutput: Specifies if the output data shall be displayed in the system monitor.
  • Note: Sets a note for this configuration.

With the buttons Receive All, Receive None, Send All, Send None, Receive Command All, Receive Command None,Send Command All, and Send Command None all OSC configuration lines can be modified together for the properties Receive, Send, Receive Command and Send Command.

Receive OSC

必要条件:

  • A network connection is established and the Interface is on both devices. For more information, see Enabling or Disabling the Network Connection.
  • Make sure that the network protocol (UDP, TCP), and the port are set correctly. Please note that the port configuration is used for sending and receiving OSC data.
    • ヒント
    If you want to use different ports for sending and receiving, you can create multiple configuration lines.

    例

      Example to receive OSC packets on a grandMA3 light console:

      1. Open the In & Out menu / OSC.
      2. Tap Enable Input. The input is enabled.
      3. Two-finger tap the first row below Receive in the grid. The parameter is set to Yes.
      ヒント
      When receiving OSC messages, Enable Input will highlight its title bar in yellow.
      ヒント
      Please note that in the example above, no prefix is defined.

      For more examples, see Advanced Examples.

      Command Line Control

      The entirety of the grandMA3 command line can be accessed via OSC by using the "/cmd" OSC Address and the string 's' OSC Type.

      ヒント

      To receive OSC messages for the command line, set Receive Command to Yes in the corresponding OSC configuration line.

      Examples that can be sent from another console to the receiving console:
      • SendOSC 1 "/cmd,s,FaderMaster Page 1.201 At 50": Brings fader 201 on page 1 to 50% (same as the examples above but using gMA3 command line syntax instead).
      • SendOSC 1 "/cmd,s,FaderMaster Page 1.201 At 50 Fade 5": Brings fader 201 on page 1 to 50% and additionally adds a fade time of five seconds
      • SendOSC 1 "/cmd,s,Fixture 1 At 75": grandMA3 command line syntax is used to execute the command "Fixture 1 At 75" in the command line.
      • SendOSC 1 "/cmd,s,Go+ Exec 402": Triggers executor 402.
      • SendOSC 1 "/cmd,s,Patch Fixture 1 3.42": Patches fixture 1 to address 42 in Universe 3.  ?

      Object Playback Control

      The Playback of the following pool objects are controlled through OSC:

      • Sequences
      • Masters
      • Groups
      • Presets
      • Sounds
      • Worlds
      • Plugins
      • Screen Configuration
      • Timers

      Pool objects are addressed by their enumerated address in the grandMA3 directory structure. For more information about the grandMA3 structure, see List keyword.
