@Natan I just checked and that click comes from the fact that the macro modulation is not sample accurate and never will be - it was never intended to be a "real" modulation system that replaces the actual modulators in HISE but just a quick and dirty way to add some movement to controls.
You can think of it this way: if the sound that you want to make could be achieved by you manually moving the control with the mouse, then the macro modulation is a good approach (eg. slow pad movements or randomized jitters). If you rely on your modulation to be exact and fast, use the inbuilt HISE modulators.
