it is a very nice idea.  Based on the results you get while testing
your external, could you somehow assess the jitter you get?  Is timing
much better than if you would have simply run

<pd-command> 2>&1 | awk '/csound/{print substr($0,9)}' | <csound-command>

and sent score line-events to [print csound] object?

Is your implementation based on print class implementation
(x_interface.c) and the family of post() routines (s_print.c)?
