	yes, it looks like the gain is initialised to 0. fshift pvshift fftin, 0, 0, 0, 1 will work. Thanks for spotting it.

	The attached csd produces a low-pass filtered sound despite the shift amount being set to zero. The result should not be altered compared to the original input sound (noise in this case).
