This means the port buffer is connected to an atom:Float, i.e. literally
points to ONE LV2_Atom_Float. NOT a sequence, or a vector. Doesn't
sound like that's what you want...

If you're doing anything messagey, Sequence is essentially always what
you want. Anything else would be a value of some fancy Atom type, which
could be theoretically useful, but isn't really supported by anything
right now.

Sorry for the late reply, fell behind on the list. Busy busy...
