Thus: An envelope generator is basically a glide circuit.
The glide circuit only has two parameters - target level, and rate.
When the gate is off, the target for the glide is zero, and the rate is the release rate.
When the gate is turned on, you enter the attack phase.
In the attack phase, the glide target is maximum, and the rate is the attack rate.
When the level reaches maximum, you switch to the decay phase.
In the decay phase, the glide target is the sustain level, and the glide
rate is the decay rate.
Now, if the gate is off, and the level is falling to zero (release), a new gate on will re-enter the attack phase.
All this means is that the glide target and rate change to maximum/attack. You do not want the current output level to suddenly jump to zero, in exactly the same way that you wouldn't want glide from one note to another to instantly jump to a note it hadn't yet reached, before starting to glide toward a new note.
The gate input can only change the selection of which rate/level are set on the glide circuit. Gate should never directly influence the output level of the glide circuit.

Anyway, started a track using Predator (gonna buy it regardless of envelopes, still have synths whose envelopes do work like an analogue). The track is kinda different, just an embryo so far.
Tonight there will be telly. Tomorrow, something like today... :)
