	Hello, I am trying to use pvsmorph to spectrally cross-fade between two sounds. But using the code bellow I get a strange result when the the morphing index (kcross bellow) is on ZERO. The result should be identical to source one but it is not, it's source one plus many fft-y artifacts. However when the index is on ONE, source 2 is synthesized perfectly. I've tried swapping my sources around and the same result, so it has something to do with the opcode I think. Any solution is much appreciated.

	The same thing is happening with pvscross too by the way.
