The initial idea for the Event Timer came to me from a Reaktor module of the same basic function which I found to be extraordinarily useful.
Have you ever paced an event to begin AFTER another one begins? One way of doing this is using a pulse delay. This will work pretty well until the duration of the original event is modified. Because the delays can't track the original, eac modification will require a reconfiguration of the preset delay time Fine if you're working with single events - but if the event your delaying is time variable, you're in for some heady readjustments.
The Event Timer ends all this set-up with a single pot setting and will track its reference signal perfectly at any speed. The two are permanently linked and not time dependant -- this device senses and responds to the amplitude of it's input against a pot variable level threshold setting. Each of the three independent comparators have a manually adjustable trigger threshold. At this point, the delays you dial-up are locked to the original and will track it's host even if the duration of the original event is modified
There is a twist to this circuit however that even the Reaktor device didn't do - not only does each comparator have it's own Q and Q not outputs, but each can run independently as separate comparators OR be linked together serially (the threshold of comparator 2 is linked to that of comparator 1, the threshold of 3 is linked to that of 2).
In this mode, all combined comparators are linked to input 1. While comparator 1 will have a free range (can be set to any reference level), the threshold level of subsequent comparators down the line can't be adjusted lower than the the one preceding it as they use each others pot reference as their lower limit - much like a parametric EQ or fixed filter bank. In this way, you can extrapolate two or three different voltage levels from one signal --> one taking the lower) range, one taking the mid and one taking higher range of the same input.

The Original Event Timer
3 independent comparators can be parametrically linked to a single input.
Summed Q and Q not outputs provide combined trigger signals of comparator 1-3 activity.
