Module: Shaper 1/2
Refresher course: Envelope basics
An envelope is a time-based process. Defined by
several envelope parameters, it modulates certain
sonic properties, for example, volume or - in the case
of Neuron - model parameters.
Playing any note triggers an audio signal
modulation, which means that the envelope
influences each note separately and explains why
the process is called multi-triggering.
A modulation driven by stick animation is, in
contrast, a single trigger function. This means that
after pressing the first key starts it, it runs through
once only (normal) or it is cycled (repeat). For more
on this, read page 103.
ADSR envelope
Like many classic synthesizers, every Neuron shaper
offers a handy four-part ADSR envelope.
The envelope is defined by four parameters; three are
functions of time and one of level:
After a note is played, the envelope rises to its peak
value within the defined attack time. The decay
parameter determines the amount of time it takes for
the curve to drop to the sustain level after the attack
phase ends (decay = fade). However, sustain does
not actually determine the period, it defines the
level at which the curve remains until the key is
released. The last phase of the curve is defined by
the release parameter. This is the time the curve
Each shaper is an extremely
versatile envelope genera-
tor. What makes it so flexible
is that the envelope can in-
fluence different parameters
and modulation destinati-
ons. Beyond that, it lets you
choose between two types of
envelopes (in free mode).
