After this patch it works without last SVN version(this bug in version from SVN too)
outputBuffers is float**,not array, its size 4.
Is it bug? :?:
(same with inputs)
Oh, I changed it from an array and must have missed that line. Your fix is correct, though I don’t think it should actually matter whether the array is initially cleared, because all the channels in it should be proper pointers, and the callback code really shouldn’t read beyond the number of channels it’s told to use.
