Hi,Dr.Heiga
Got it,Thanks for your detailed explanation.

Hi,

In the file "reg.base", it's written:

 <CLASS> 1 {dh^ih-s+p.......state[2].stream[4].mix[2] ..........

 here, let's assume "dh^ih-s+p........state[2]._stream[4].mix[2]" as the second mixture of  the stream "~p "lf0_s2_47-4".
Actually, there're a lot of "~p "lf0_s2_47-4" in the model file "MMF".
 Then my questions are listed as follows:

 1.when classing (generate the "reg.base" file), I think HHEd tool using "dh^ih-s+p........state[2]._stream[4].mix[2]"  as a delegate for so many "~p "lf0_s2_47-4" in the model file "MMF", just because it's found firstly when classing, is it so?

Yes.

2.Does HTS do adaptation of the second mixture of MSD?

No, they are 0-dimensional distribution and they are skipped:

HAdapt.c:

Boolean GenXForm(RegNode *node, XFInfo *xfinfo, IntVec classes, int xfindex)
{
 AccStruct *accs;
 int class=1,b;
 IntVec blockSize,bandWidth;

 AdaptXForm *xform = xfinfo->outXForm;
 AdaptXForm *diagCovXForm = xfinfo->diagCovXForm;

 if (node->valid && node->vsize>0) {
                    ^^^^^^^^^^^^^^

node->vsize is the dimensionality of distributions clustered in this node.
