Since LADSPA does not specifiy that control values are
valid at
activate(), either
1. the first sweep has to start from defaults,
2. or it has to be replaced by a jump to the current control values.
For 2. keep a boolean indicating that the current control values
are valid and can be used as the starting point for interpolation.
Reset in activate(), set in each process().
I've thought of 2. too but would prefer a host side solution because
* you only have to do it once per host, not once per plugin
* it keeps the plugin code simple
* it is more efficient
But I guess that you are right and I should simply do 2. -- or are
there any host authors out there who think otherwise?
