Subject[Cs-dev] small bug in pvsfilter
hi -

there is a small bug in pvsfilter. if the optional igain parameter is 
set to a value different from 1, there is no more cross synthesis. 
instead, it sounds as if the amplitudes of the fsigin stream are 
multiplied by themselves.

see, for instance, the manual example pvsfilter.csd, and replace line 
30-34 by this:

if ipermut == 1 then
fcross		pvsfilter	fftin2, fftin1, 1, .5
else
fcross		pvsfilter	fftin1, fftin2, 1, .5
endif

best -

	joachim
