It would be no problem to introduce a property, where the plugin actually
defines the datatype it wants to use and the host would have to do the
right conversion. Wouldn't complicate ladspa too much I think.

It should be no problem to write a wrapper for ladspa plugins. But I just
like to know how you handle the case, when the output buffer is larger
than the input buffer, when you use effects like echo, delay, etc. The
host would have to send an extra zeroed buffer, that has for example the
size of the ringbuffer that has to be emptied. The host should be able to
query that, if not the host could still sent zeroed buffers and check if
they're coming back empty, but somehow I don't like the latter one.
Cheers, Alex
