ah yes .... if I'd paid more attention to the error message .....

Now I've come across an other problem (which perhaps invalidates the
null reader solution?) the LADSPA plugin has 4 output channels.... it
seems that the plugin writes to the same buffer as the input
channels... there is no error thrown from the LADSPA wrapper itself,
but when I try to save the 4 output channels (as mono) the 4th one
doesn't exist ...

I guess maybe I should revert top Kjetil's suggestion?
