Hi community,

(*sn1 for SoundNote pitch, sn2 for duration of according note*)
sn1 = {-9, -9, -5, -5, -9, -9, -9, 3, -7, -7, -7, -4, -4,
   0, -4, -7, -2, 5, 10, 10, 2, 2, 5, 2, -9, -9, -5, -5, -5,
   3, -9, -2};
sn2 = {.00001, 1, 3, 3, 1, 1, 3, 3, 1, 1, 3, 3, 1, 1, 3, 3, 1, 1, 3,
   3, 1, 1, 3, 3, 1, 1, 3, 3, 1, 1, 3, 3, 1, .00001};
sn2c = Accumulate@sn2/8;
sn2s = Table[{sn2c[[i]], sn2c[[i + 1]]}, {i, Length[sn2c] - 1}];

(*pos changing according to Session Time, in order to get
corresponding note in sn1*)
pos := Position[sn2s, {_, _}?((#[[1]] < t <= #[[2]]) &)][[1, 1]];
pos1 = pos;
pos2 = pos;

(*offset as the name means, t for time starts form offset*)
offset = SessionTime[];
t := SessionTime[] - offset;

I'm really puzzled by the following codes:

Dynamic[
 Clock[1];
 Panel[
    If[pos2 != pos1 && t < 8.1,
      pos2 = pos;
      pd = dancer[1, RandomInteger[{1, 20}], locators];
      EmitSound[
      Sound[
      SoundNote[
      sn1[[pos]],sn2[[pos]]
      ]
      ]
      ]
      ]


    ]
   pos1 = pos;

 ]

I meant to emit sound and display a dancer figure corresponding to
every change of sound while time passing, but I can't realize it.

How to do it?

Thanks a lot!
