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().
