Ok. Then we can just increase the accuracy and that should solve that.

As for LADSPA, things are a bit different there... there's no set step
size, instead, we just choose a set amount of steps within the range and
the step size will be range/amount. I recently increased the values we
use there, so that the step sizes are smaller (can't remember if this is
in 1.1 or master only). Also automations no longer get quantized to step
size but instead move smoothly between them, so that should also help there.
