It's likely that I'm overlooking something glaring here, but I can't get the code below to compile. I've looked at the method in the documentation, but I'm still not sure what I'm doing wrong.

This is from the Writing Max Externals in Java document.

   private Executable e = new Executable()
     {
        public void execute()
        {
          outletBang(0);   //send a bang out the first outlet
        }
   };
  public void bang()
  {
     scheduleDelay(e, 2000);
  //call the execute function of e
  //2 seconds (2000 ms) from now.
  }


cannot find symbol
symbol  : method scheduleDelay(com.cycling74.max.Executable,int)
location: class slow
     scheduleDelay(e, 2000);

As is the nature of these things - I've run in to another problem.

At the moment I'm embedding global variables (which are set during each incoming MIDI note) directly in the execute method. Basically I have a mish mash of incoming notes / function calls that don't correlate.

Is there a way of passing arguments to the Executable object?

You can pass arguments to a constructor when you build the Executable (using a subclass). If you want to pass values into the Executable itself (and get into the whole fun world of multithreaded programming), you're best off using some kind of queue. What are you trying to achieve?

I'm trying/failing to delay multiple MIDI notes

I'd personally do that with some kind of queue, but as a quick-and-dirty hack you can just fire off a new Executable for each note. (Max will re-synchronise all the delayed output calls correctly.) Create a subclass of Executable with a constructor taking whatever parameters are specific to each note.

I'm still stuck with this - do I need to create a subclass in a separate java file?

I've had a bash at a few different methods but can't get any to compile properly (also done a bit of reading but feel I'm a bit out of my depth).
