After gotten the advices I tried to use the wg-opcodes again and can not figure
out, how to use them:

Your first examble works fine.
a1  	wgflute  30000, 400, 0.2, 0.1, 0.1, 0.15, 0, 0, 1, 50

But this works not as expected (csound version 3.52 at Linux 2.0.35): 
a1  	wgflute  kamp, 400, 0.2, 0.1, 0.1, 0.15, 0, 0, 1

The first note of a score will not be played, so if you try only one note you
get nothing.


Your second example does not work either (on my maschine):
a1  	wgflute  30000, kfq, 0.2, 0.1, 0.1, 0.15, 0, 0, 1, 50

csound needs allmost all of my cpu power and seems to do nothing for a long
time (!?)

Futhermore iminfreq seems to have an influence on the pitch:
a1  	wgflute  30000, 400, 0.2, 0.1, 0.1, 0.15, 0, 0, 1, p4

with:
f1 0 8192 10 1
i1 0 2 200
i1 + 2 300
i1 + 2 399
e

same with kjet:
a1  	wgflute  30000, 400, p4, 0.1, 0.1, 0.15, 0, 0, 1, 50

f1 0 8192 10 1
i1 0 2 .1
i1 + 2 .2
i1 + 2 .3
e

(And I can't notice the difference in the noise-amount)


But perhaps the failure is quite another, in this example nothing changes but
every note is different (!)
a1  	wgflute  30000, 400, .1, 0.1, 0.1, 0.15, 0, 0, 1, 50

f1 0 8192 10 1
i1 0 2 
i1 + 2 
i1 + 2 
i1 + 2 
i1 + 2
e

(This effect will be gone, if an other kjet is used, say 0.2)

A similar effect can be tried with:
a1  	wgclar  30000, 400, .2, 0.1, 0.1, 0.15, 0, 0, 1, 50

f1 0 8192 10 1
i1 0 2 
i1 + 2 
i1 + 2 
i1 + 2 
i1 + 2
e

Here kstiff seems to be changed without really be changed but happily no side
effect in pitch happens.

Sorry, but do I really missuse these opcodes?

hoping for some fixes
