  • Parameters:

  • offset (double): The time offset in microbeats when the event occurs.

  • sink (int): The sink index where the event originated.

  • lane (int): The lane or output group index.

  • pitch (float): The pitch of the note.

  • velocity (float): The velocity of the note.

  • Example:

    // Subscribe to the Note On event
      onNoteOn += RouteNoteOn;
      
      // Example callback implementation
      void RouteNoteOn(double offset, int sink, int lane, float pitch, float velocity)
      {
      // Do Stuff
      }

RouteNoteOff​

  • Return Type: void

  • Summary: Subscribes to the callback for Note Off events.

  • Description: Invoked when a "noteoff" message is received from the Reactional Engine. This callback processes note-off events, providing details such as the event offset, sink index, lane index, pitch, and velocity.

  • Parameters:

  • offset (double): The time offset in microbeats when the event occurs.

  • sink (int): The sink index where the event originated.

  • lane (int): The lane or output group index.

  • pitch (float): The pitch of the note.

  • velocity (float): The velocity of the note.

  • Example:

    // Subscribe to the Note Off event
      onNoteOff += RouteNoteOff;

      // Example callback implementation
      void RouteNoteOff(double offset, int sink, int lane, float pitch, float velocity)
      {
      // Do Stuff  
      }

RouteStingerEvent​

  • Return Type: void

  • Summary: Subscribes to the callback for Stinger events.

  • Description: Invoked when a "stinger/start" or "stinger/stop" message is received from the Reactional Engine. This callback handles stinger events, providing the time offset, whether it's a start or stop event, and the stinger's origin.

  • Parameters:

  • offset (double): The time offset in microbeats when the event occurs.

  • startevent (bool): Indicates whether the event is a start or stop of the stinger.

  • stingerOrigin (int): The origin of the stinger event.

  • Example:

    // Subscribe to the Stinger event
      stingerEvent += RouteStingerEvent;

      // Example callback implementation
      void RouteStingerEvent(double offset, bool startevent, int stingerOrigin)
      {
      // Do Stuff
      }

RouteBarBeat​

  • Return Type: void

  • Summary: Subscribes to the callback for Bar and Beat events.

  • Description: Invoked when a "bar" message is received from the Reactional Engine. This callback processes bar and beat events, providing the time offset, bar number, and beat number.

  • Parameters:

  • offset (double): The time offset in microbeats when the event occurs.

  • bar (int): The bar number in the current sequence.

  • beat (int): The beat number within the bar.

  • Example:

    // Subscribe to the Bar and Beat event
      onBarBeat += RouteBarBeat;

      // Example callback implementation
      void RouteBarBeat(double offset, int bar, int beat)
      {
      // Do Stuff
      }

RouteAudioEnd​

  • Return Type: void

  • Summary: Subscribes to the callback for Audio End events.

  • Description: Invoked when an "audio/end" message is received from the Reactional Engine. This callback handles events that indicate the end of an audio sequence.

  • Parameters: None.

  • Example:

    // Subscribe to the Audio End event
      onAudioEnd += RouteAudioEnd;

      // Example callback implementation
      void RouteAudioEnd()
      {
      // Do Stuff
      }
