Hi all,
I just uploaded a pdsend LADSPA plugin on this page:
http://icem-www.folkwang-hochschule.de/~finnendahl/pd.html
It is called pdsend_3113 and it can be used for the remote control of fader automation in pd by host applications like ardour.
There is an example included.
Unfortunately linux only (or are there any ports to LADSPA for other platforms?)
