William,

I compiled your ORC & SCO file and met with the same phenomena as you
did.  Then I tried the example in the Csound 3.47 manual -- nothing
happened at all.  It is listed below:

	kv	linseg	0, 0.5, 0, 1, 1, p3-0.5, 1
	ar	wgbow	31129.60, 440, 3.0, 0.127236, 6.12723, kv*0.01, 1
	out	ar

After doing that, I began to think that it might be another bug.  To
find out whether it is or not, I compared your file and the example in
the manual.  Then I replaced the costant 31129.60 with iamp.  Still,
everything was OK.

The last thing I did was replace 440 with kfreq, Csound hung up!!!

Is there anyone else can explain it?

PS. "i6" in your SCO file should be changed into "i1".

Regards
Qian Chen
