As already stated, I am a newbie on this list, so never mind if my
questions
are stupid...

As I am interested in software synths, I wonder how e.g. the parameters
of a synthesizer like the DX7, can be handled using LADSPA.
The DX7 has several (>80) parameters to set, and it seems to me a bit
of an overkill to export and manipulate each parameter using a control
port.

Wouldn't it be sufficient to know the index of the parameter and
change/get
values using two generic access functions like (pseudo-code):

void set_parameter_value(Handle, ParameterIndex, ParameterValue)
LADSPA_Data (*get_parameter_value)(Handle, ParameterIndex);

So long,
  Jürgen
