I was having no success at first, but then I found that
removing the ispecwp flag avoided the crash.  The strange
thing then, was that the file came out 8 times too slow.
I changed the 'line' line in the orchestra to:

ktime   line    0, p3 / 8, 1

and the sound played at the correct speed.

Thanks,

Tobiah

I don't know why I assumed that it was normalized to the length of the
file.  Thanks.

As to the crashing, I notice that Aaron Johnson reported the same thing
on October 25th.


Toby

I wasn't aware of these.  Thanks for taking the time.
I'll definitely experiment after work.

I would be great to have a chronological listing of
opcodes.  I'm back into Csound after several years
of absence.  It would be great to see the list of
what has happened since then.

Would it be difficult to compile a list of release
notes for instance?

Thanks

Toby
