video or demonstration please.The ideal "click" is a dirac delta function: an infinitely short spike with finite area. In DSP it is naturally approximated with a one-sample spike, step function, or fancy bandlimited version of the above.
How to make that with a synth? Use a square wave oscillator pitched very low with a very short AD envelope. Very handy for pinging filters if a synth lets you modulate osc volume pre-filter.
How to get that with some sub? Use a low sine oscillator with longer amp release and fix a non-zero start phase, so it begins with a sharp step to the waveform.
But that's not how most drum synths do it? Right. The frequency spectrum of our dirac delta is "all frequencies equally loud". So to get quite a short sound with all frequencies we can take an oscillator and quickly sweep through them. High to low is preferred because it ends in the right place. That classic "fast pitch bend sine osc" kick start is equivalent to our delta function running through an allpass filter. When we play with the decay curve, this is effectively changing the phase shift and frequency balance.
