Reusing Global Rackspace components across songs

General discussion about Gig Performer
6

I must admit I’ve not thought about using the GP plugin presets as a way to load files per song. But it does work…

  • ‘Gig Scripts’ can detect when a song has changed, but this level of script cannot interact directly with widgets or plugins.
  • So instead, you can get the Gig Script to send an OSC message that contains the selected song name.
  • This OSC message is received back by GP, and detected within the ‘Global Rackspace Script’ (which CAN interact with plugins).
  • The Global Rackspace Script then loads the AFP plugin preset that has the same name as the selected song.

  1. Activate OSC in the GP Options

  2. Add this to the Gig Script editor (Window menu) and click Compile

// Called when you switch to another song
On Song(oldSongIndex : integer, newSongIndex : integer)
    OSC_SendStringSpecific("/GP/Song", GetSongName(newSongIndex), "127.0.0.1", OSC_GetGPListeningPort())
End

  1. Add an Audio File Player plugin to the Global Rackspace and add an OSC/GPScript Handle (via right-click menu). Call it “AFP” and tick the box for “Use in GPScript”

  2. Add this to the Global Rackspace script editor and click Compile

Var
   AFP : PluginBlock

// Called when a specific osc message is received
On OSCMessageReceived(m : OSCMessage) Matching "/GP/Song"
    LoadGPPreset( AFP, OSC_GetArgAsString(m, 0))
End
  1. Now, when you switch songs, the AFP will attempt to load a plugin preset that matches the name of the selected song. You will see a confirmation (or error) in the header/title area of GP if it finds a matching preset and successfully loads it.
