When using Renoise’s Filter effect on a drum loop. i get a click when starting the cutoff envelope at the start of the pattern
maybebecause its moving from the “old” setting to the one set in the envelope. you an either set inertia to 0% (or 100% ? not sure at the moment) or set the cutoff to the value with which the envelope begins using a effectcommand. (or atleast near it)
