I should hope loscil should default to looping the whole sample.

I tried your suggestion. (Thanks; I didn't know about nsamp.) Unfortunately,
I still get:

opening AIFF infile C:\My Documents\My Music\SEAMUS\Good\Seamus2norm.aiff
INIT ERROR in instr 1: deferred-size ftable 1.000000 illegal here
isamps nsamp.i 1
INIT ERROR in instr 1: illegal sustain loop data
a1 a2 loscil kamp 1 1 1 1 0 isamps -1 0 0
   B  0.000 - note deleted.  i1 had 2 init errors

I also note the new (second) error. In the meantime I had reinstalled
Csound5.02 beta (Gogins installer); don't know whether this is related or
not.

BTW, it installed libsndfile-1.dll, just as it did before. Perhaps this is
the problem?

Hi Art,
Audacity seems not to be able to generato loop points, but if no loop
points are specified, shouldn't loscil default to the whole length?

I think you might need to specify both loop points since csound seems to
think you want to loop between 0 and 0...

Does this work?

isamps = nsamp(1)
a1,a2  loscil kamp, 1, 1, 1, 1, 0, isamps

Cheers,
Andrés
