Subject: [sc-users] ATK Help Example -- confused
To: <[email protected]>


Here is the Post window output when I try a (slightly modified) version
of the ATK help example illustrating Transformation via Pink noise --
the source code follows below.

There is a similar example in the FoaDecode help examples that uses
global variables and no Synth that works without error.

This error message has shown up previously, back in 2012 but the poster
was developing a class and using Ndef for testing; here's the link:
http://sc-users.bham.ac.narkive.com/Xyi9zkrt/atk-problems-with-binaural-foadecoderkernel

I suspect it may be some sort of variable scope issue but I don't
understand why the variable initialized with FoaDecoderMatrix works
while it doesn't when initialized with FoaDecoderKernel. And why the
code decoderkernel version works when using global variables. (Although
there was a response having to do with which version of the server was
needed.)

Thanks for your help.        ...edN
