Hello,
I have a question regarding the Csound API for Java. I was trying the final
example in this article:

http://www.csounds.com/articles/RoryWalsh_CsoundAPI.pdf

I wanted to try out the function: 

PUBLIC int csoundScoreEvent(CSOUND *, char type, const MYFLT  *pFields, long
numFields);

with the java csound api, which is:

public int ScoreEvent(char paramChar, SWIGTYPE_p_double
paramSWIGTYPE_p_double, int paramInt)

In the example mentioned in the article the array of doubles is passed to
the function but in the Java version you can only use as a parameter a
SWIGTYPE_p_double therefore you can’t “send” an array of doubles or at least
that’s what I think since you are not really using a pointer.

Is there a way to use this function in Java?

Hi David,

I'm not sure if there is a way to use it.  You can manipulate MYFLT*
(or Swigtype_p_double) from Java using a CsoundMYFLTArray, but that
only wraps an existing MYFLT*. There's a MyfltVector class generated
that comes from the CsoundCPP source file, but I don't see any way to
use that either.

I usually send score as text to Csound using csound.InputMessage().
Have you tried using that?

Would it not be easier to use csoundInputMessage()?
