hello bryan,

the buchla 281e can also work as attack-release envelope
and it can function as a four-output quadrature envelope.
also the separate generators can be linked together by
a logic function to act as a complex envelope (in a different
way than the a143/1 i believe).

the a143/1 has the ability to mix all envelopes in order
to generate a complex envelope and it has adjustable
comparators built-in for automatic triggering.

quite a different set of features ...

best wishes

ingo
