mono --> stereo plugins crashing AU validation under Logic 9.1.5

I've re-compiled them and reinstalled... no help.



Any thoughts?

Hi,

did you find a solution for this? I just encountered the same problem and I don't find a solution...

Many thanks...

Hi,
No, nothing that I have tried has solved this issue.... hmmm....

Here is the CRASH report from Apple's AU Validation tool after re-scanning a MONO-->STEREO plugin ( in this case my Eventide "Instant Flanger" emulation).
All MONO-->STEREO plugins , even my simple M/S "Side \" decoder (simply takes one input and outputs 2 channels in inverse polarity) give the same error: "ERROR: Output Buffer Size does not match requested num frames"

Hi,

I had similar problems with surround plugins when the number of inputs didn't match the number of outputs.

Have you tried to set a dummy 2nd input ?

[zmix]

Could you explain what you mean by a "dummy second input"?
If I were to specify a second input in the plugin descriptor, it wouldn't appear in the plugin list for a mono track as a M->S option.
