      All of those instruments contain noise.  Likely a Noise object.  Wonder if Noise itself does a seed?  I'll check.

Forgive me if this was already discussed on the list before.  I am puzzled about a non-random random number.
When the random number is calculated right after an STK instrument is declared, the result is not random.  It is the same number every time.
However, if the same code occurs without an STK declaration before it, the result is random.

StifKarp stu => dac;
int randy;
Std.rand2(0,10) => randy;
<<<"here are three random numbers",
Std.rand2(0,10), Std.rand2(0,10),Std.rand2(0,10),
"and NON-random Randy", randy >>>;
Std.rand2(0,10) => randy;
<<<"here are three more random numbers",
Std.rand2(0,10), Std.rand2(0,10),Std.rand2(0,10),
"and random Randy", randy >>>;
1000::ms => now;
