The top input of the envelope is a gate input, which works similarly to the gate
inputs of primary-level envelopes—that is, it opens or closes the envelope in
response to incoming events. For that we create an event input for our core
cell:
This input will translate the incoming primary-level gate events into the core
events.
Now let’s take a look at the A, D, S, R inputs. The S (sustain level) input
works similarly to the primary level; it expects the incoming signal to be in
the 0 to 1 range:
The A, D, R inputs are different, however. Unlike primary-level envelopes they
expect time to be specified in seconds:
That can be solved by using a Standard Macro > Convert > logT2sec, which
converts the primary-level envelope times to seconds:
Although all inputs in the above structure are in event mode, the first input
produces an event signal, whereas the others produce control signals.
Our envelope still has two unconnected ports. The GS port sets the gate
sensitivity amount. At 0 the envelope completely ignores the gate level and
