Hi, 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 ardour. That way, pd can be used for the development and prototyping of plugins or a LADSPA host like ardour can be used as a high resolution sequencer of control signals for pd patches. An example is included. -- Orm
