Re: [sc-dev] crossfading groups, noid for groups

Hi Julian,

I'll take a look at AbstractEnsemble and GraphBuilder.

BTW: GraphBuilder is in Common/Control.  Is it used by classes other than
those in JITLib?

Also, in GraphBuilder, is there some reason wrapOut hs:

env = if(fadeTime.notNil, { this.makeFadeEnv(fadeTime) }, 1);
	result = result * env;

rather than

if(fadeTime.notNil, {
	result = this.makeFadeEnv(fadeTime) * result;
});

PS: Here's a probably impractical thought:

With an "n_duplicate" command simple texture xfade could be done mostly on
the server.  (This may be too bursty to be permissible, but it would be
a simple solution.)

	n_duplicate: duplicate target (including ID's), replace original's
ID's with  server allocated ID's.

	then it would be:
	g = some group or Synth

	[n_duplicate, g.nodeID]
	[\s_new, "fadeOut", g.nodeID,\addBefore]
        [\s_new, "fadeIn", g.nodeID,\addAfter]
	[\n_set,....any new params]
