[Dev] gui instance host question

[Stephen Sinclair]

Hi,

Say, theoretically, that a GUI has its own instance host (and bridge)
instead of relying on OSC to communicate with Integra.  The examples
in library/trunk show that a Pd server (audio engine) can respond to
OSC messages from a GUI, where examples are given in Python and Pd.
However, if the *GUI* already has its own instance_host, can it not
communicate with the instance_host directly instead of sending OSC
messages?  That is, does the instance_host provide a C API similar to
the OSC messages it handles?  When the bridge calls "ih_callback", it
seems to be limited to messages that change port values.  How would a
bridge be used to create and connect module instances?

If the answer is _no_, what is the role of the instance host in the GUI?

thanks,
Steve
