THE ENVELOPE
Envelope generators are one of the most important sources of control voltage in any
modular synthesizer. Though they might not generate audio signals themselves, many
iconic sounds like the squelchy acid bass line, snappy techno kick drum and swelling
dream pop pad wouldn’t be possible if it weren’t for envelope generators. So I knew I
needed one for my DIY modular –
which is why I created this wily little fake-ADSR.
Why fake? Because though it does send out a four-staged signal ( a ttack/ d ecay/ s ustain/
r elease), the duration of decay and release are tied together, controllable only via the
same knob. To make up for this limitation, I decided to include both a looping function
and an inverted output as extra goodies.
