Yep, thats why the plugins have to tell the host how many samples they create
from the number of input samples. (With the default of the same number of
samples...)
But the host should _never_ force a plugin to do resampling/time-stretching!
Because it opens a pandoras box of bad quality!

Well, your first proposal was a "universal" plugin API!? Being universal is
one of the things you wanted in the first place. And its why LV2 supports
extensions...
