make noise maths vs mutable kinks Kinks functions: full-wave rectifier: mult signal to input 2 and 3. channel 2 full clockwise, channel 3 full counter-clockwise, rectified output from maths "or" output half-wave rectifier: mult signal to inputs 1, 2, 3, 4 - take output from "or" output signal invertor: apply signal to 2 or 3, take output from the "inv" output Logic: and - one or more inputs to 1, 2, 3 or 4 - take "sum" output or - one or more inputs to 1, 2, 3 or 4 - take "or" output sample and hold : not possible
