Zig Zag Delay 2 is out now. Free to my Buy Me A Coffee subscribers.
I’ve added independent control of both feedback paths, as well as filters and pitchshifting in the feedback. The upgraded algorithm easily creates pitch spirals, natural delay tap decay, and the filters can be modulated for resonant filter effects in the feedback path. There are a range of presets included for both algorithms to get you started.
Here is the updated block diagram of the algorithm.
