This is a slightly confusing way to put this. This is based on the idea of the
ADSR type envelope generator. The ADSR envelope generator is actually
a sub-patch on generalized style modulars like Buchla and Serge.

1. The trigger from the keyboard is routed to one AD envelope generator.
2. The gate from the keyboard is routed to another AD envelope generator.
3. The outputs of the two AD generators go to a CV mixer.

Various settings give the usual envelopes, note that you have two attack
controls which can be used for unusual effects.

Neither the Buchla nor Serge systems have dedicated low frequency
oscillators. The AD envelope generators have "end of decay" outputs
that go high when the output voltage falls below about 50 mv.
If you patch this back into the input the envelope generator will
oscillate and that is used as an LFO. (won't produce square waves though,
the only way to get a low frequency square wave on a Buchla 200 is
to use a sequencer set to 2 stages).

You can also use one section as a gate delay or chain multiple sections
into "ramp shot" sequencers (sequences which are a series of envelopes).
The only ADSR design that seems to have this function commercially
is the DIGIDESIGN units which have a delay/recycle switch. 

Any DIGIDESIGN user's out there that can comment on this function?

Be Groovy,
