I think my current problem is because the wrapping of chanOx and
chanIx are just wrong.  The numbered software bus is a unidirectional
one, so when csound uses chani the application needs to use chano and
vice versa.  This is not what is implemented, so as it stands when
attempting to transfer data it crashs at the java end.
  If this analysis is correct, then either the API needs fixing, or
the code in OOps/bus.c lines 93-177 needs rotating.  As the API is
clearly wrong and cannot be used it does not matter much which one
does, but the current situation is wrong.

I am not sure anything needs to be done. I am quite sure I used the
chani-chano set at least for tests and it worked OK for me. I used

csoundChanIKSet() to send a value to csound to be received by chani,
and csoundChanOKGet() to get a value from chano. Similarly,
I used csoundChanIASet() to send a ksmps vector and csoundChanOAGet()
to retrieve one from Csound.

And also very importantly, I based csoundPvsinSet() and csoundPvsoutGet()
on the same principles. So if there is change, these two will also have to
be looked at.

At the moment, I can't understand the problem. Perhaps you can explain it
to me. From the C API perspective, I did not have a problem using these
functions.

I have taken a further look at the code and now conclude that it is
correct; I think th eproblem lies in my continuing problem with in versus
out (a mild form of dsylexia)

The trouble is that there is no documentation for the Java wrappers, and
as i do not know Java i am finding it hard to implement the code.  The
student claims to know Java but not Csound (or audio at all)

I will try again......
