Sorry for replying twice, but an afterthought: Is it possible to
dynamically change the number of control ports in LADSPA? E.g. if
you have a 32 band graphical EQ and want to make it use 64 bands,
would you have to create a new plugin instance with the
appropriate parameters? Or would you have to write a separate
plugin?
Thanks,
