hello

just trying out scripts in usine.

the one below is very basic, it just connects one output to an input.
(in a nearly empty patch, just 2 subpatches with dummy ins/outs).
it works but it takes nearly 1 second to connect/disconnect.

so:
- is it because of some code uglyness or is that intended (i.e. this method should *not* be used in an audio context) ?
- the same thing in a "Send Usine Internal Messages module" does not have this problem (but is much less flexible).

thanks for your hints.

Code: Select all

&#91;snip&#93;
Procedure Callback&#40;N&#58;integer&#41;; 
BEGIN

  if &#40;n = InCmd&#41; then begin

    if &#40;GetValue&#40;InCmd&#41; = 1&#41; then begin

      cmd &#58;= 'CREATE_LINK';

    end
    else begin

      cmd &#58;= 'DELETE_LINK';

    end;

    SendInternalMsg &#40;'SET_TARGET_PATCH','SENDER_PATCH'&#41;;
    SendInternalMsg &#40;'SET_TARGET_PATCH', '1', '1'&#41;;
    SendInternalMsg &#40;cmd, 'foo', 'output', 'bar', 'input'&#41;;

  end;

END;

globally IML is not targeteted at real time audio applications, even if it can performs very decently very fast, in some data cases
as i saw with the vst automations send via IML, however i feel the thing that can be really slow here is the
the process of creating/deleting wires or modules, cause it's not a priority process and take a certain amount of time.
maybe try in init to set InCmd FastCallback using
SetFastCallback(inCmd, TRUE); and disable undo could speed up a bit the thing, but not sure it can be really increased.
(don't remember but there is a command to send for usine to bypass undo, think it's in wiki)

I feel such 'audio Dispatcher' would work better with a real modules wiring indeed.
IML could be cool for adaptative changing setup, but not real time audio switcher.
as creating/deteleting wires is not as efficient as changing a dispatcher nb.

thanks for your advices, that's more clear for me now

yes this part of the IML is processed as a very low priority task.
In an audio process it can be used only in extreme circumstances.
But it's an interesting way to explore!
