Sorry I probably confused you with my "CREATE" suggestion in the last 
email.  It was late last night and I'd spent the entire day staring at 
source code of one form or another... I haven't done SQL since my 
undergrad.  ;-)

I really did mean INSERT, I swear.

Thanks for your replies, I'm currently absorbing them.

However I'll just take the opportunity to ask a question now that I've 
slept on it...

Assume a GUI module (say, slider) is instantiated.  I am guessing that 
this module should then be actually represented in two instance_hosts.  
The GUI has one instance_host and the Engine has another instance_host.  
(Each with their own bridge.)  I am assuming that communication between 
these two instance_hosts will take place, somehow, so that the slider in 
the GUI can send information to the slider in the Engine.

Well, one thing to think about is that the Engine may place the instance 
somewhere.  (You could open the resulting Pd patch and it should be 
legible, right?)  The GUI may also place the instance on the screen 
somewhere when viewing the routing configuration.  Additionally, the GUI 
may place the slider instance somewhere else for what we are calling the 
"performance pane".  Is it correct to assume that all these things will 
be saved as instance attributes?

slider:
  - value
  - name
  - performance/css stylesheet for [type (knob/slider), color, style, size]
  - performance/x
  - performance/y
  - routing/x
  - routing/y
  - engine/x
  - engine/y
  - connections

Is this the right way of thinking about attributes?  An instance really 
has several attributes that are not necessary in the module definition.  
Does that mean that instances have multiple inheritance with an 
"instance" or even "GUI instance" class?  How do "subattributes" come 
into play here?


cheers,
Steve
