Hey Frank,

I agree, what you did with using my OSC routes (in and out) is what I
was hoping to be able to do. This could be a good way for approching
the design for RRADical. I started making a new object for v_ that
uses the internal OSC messages to control other GOPs. Problem is that
I did not put OSC directly in this thing, because the Gops with it is
controlling are the ones that send the OSC commands. It would be
redundant (and probably problematic) to have both sending OSC
commands that end up doing the same thing. Because v_fade does
not have OSC sending commands (it does have OSC receiving) then
the state could not be saved using this method...

Any ideas for a solution? I can see how a "meta-controller" that just
controls other abstractions could be useful for other applications...

done. (I'm not sure why the mime-type is not enough.

Thanks! It will be pretty cool to have an integrated suite of such things.

Visible abstraction arguments is for sure an issue, I took them out
because the only argument (the name) is in the canvas name, and
because it takes up too much screen-space (these damn v_ things
really need at least a 1024 high screen!) It does make it hard to
change the name after creating the object...

very nice. The reason why OSC was not an abstraction is that each
GOP have a different number of controlls, so ideally an OSC abstraction
would dynamically created the right number of inlets and outlets and
know what to do with the data. (This is the only reason why OSC is not
an abstraction in the first place!)

It does sound great, I'm looking forward to what comes out of all this.

This is so that the OSC-in and OSC-out namespace is different, otherwise
the GOPs respond to outgoing messages!! and some bizarre feedback ensues..
