Hello!

   So I had another small look at liblo and the dssi plugins. Here's what I

gathered, correct me if I'm wrong:
HOST side:

   * The host creates a server_thread and attahces methods to it, which change

engine paameters according to incoming lo_sends.

   * But the engine itself must use lo_send, when it updates parameters due to

new patches loaded or other sources of outside control, right?
CLIENT side:

   * The client also should have a thread connected to the server, so it can

see

updates and changes based on engine/server changes

   * The client must have other methods attached to it - if that is possible -

to just change the display of the UI.

   * the client must lo_send user-changes to the server.
   Did I basically get this right? I've seen no way to query the lo_server for

existing paths or types of certain nodes.

   So paths and types must be included in a description file.

   One node (OSC parameter) can have several values attached, these can be of

different types (float, int, string,...). To make sense, they have to be in

the order determined by the Engine developer.

   So for the UI/client side one must first somehow find or be given the

server-adress, read the description file, build the tree structure. Then one

must send out a message to the server, that one would like to have current

info on all the nodes. So the engine can go through its internal values (the

real thing) and lo_send each parameter again/or for the first time.

   This will mean, that we have at least one OSC-path for internal

server/client communication. It wouldn't need to be standardised, but it might

be nice. You can always put that "query_all" path into the description file as

well.

   Did I miss anything important for a start?

   Warm regards

            Julien
