MOTM

My understanding is that it is an AR if fed a trigger and an ASR if fed a
gate.

I could be wrong; it _is_ a _Wednesday_.

AD? You mean it would peak and then decay to some sustain level? Doesn't it
'Release' back to zero?

		In ADSR terms, you'd have an AD if fed a trigger, an ASR if
fed a gate.

Nah, forget what I just said. This Wednesday crap is catching...

I'm distracted by work and can't think straight. An AR envelope generator
would only require a trigger, correct? Or the leading edge of a gate? The
gate length is irrelevant, correct? Otherwise it would be ASR? Why am I so
clueless today? Anyday?

What I mean when I say AD/AR EG is that the output would be switchable 
between one setting (AD) which will go from an attack phase immediately to a 
decay phase (turn your sustain to zero on your ADSR to experiment with this), 
and a second setting (AR) which will act like an ASR EG with the sustain 
length being determined by the gate length (turn your decay to zero and your 
sustain to maximum on your ADSR to experiment with this one). I believe this 
is an (almost) standard distinction and the reason I suggested it is that 
there seems to be little additional circuitry involved between these two 
types of EGs, but being able to switch between these two is quite useful. I 
might also suggest that such a module might only accept one pulse input per 
EG so it will typically "expect" to see a gate, but can equally operate via a 
trigger (which would naturally give only AD response regardless of the 
switches setting). I'm not at all sure that this part of the circuit would 
work, however.
