From the
Peak Level
, there’s a decay stage to the
Sustain Level
, whose duration
is set by the
Decay Time
. These parameters can be found on the Env Decay page.
You can
Arrow Right
to get to this page, or press the back button and tap
Env
Decay
.
Arrow Right
again, or tap
Env Release
to get access to these options:
Sustain Level | Release Time | End Level
The
Sustain Level
is the same parameter as the top-level
Cut Off
parameter,
just with a different name in this context. It’s the level at which the filter cut off
frequency is sustained after the attack and decay stages complete.
As per the other envelopes, we have a release stage, which begins when a
note off event is received / finger is lifted. The
Sustain Level
will head towards
the
End Level
and the time this takes is set by the
Release Time
parameter.
6.4. Subtractive Synthesis
Subtractive synthesis takes the opposite approach to additive synthesis. Rather
than start with a sine wave and add harmonics to it, we start with a more
complex wave and filter out stuff we don’t want.
We can’t talk about subtractive synthesis without mentioning filtering, so if
you haven’t read those sections yet, go back and check them out. Additionally,
there is a simple multi-mode filter provided on all subtractive generators, whose
settings are per-partial. This is very useful for crafting sounds for different areas
of the keyboard, or processing the same oscillator differently based on the filtered
output, so for instance, sending only the higher frequency content to a reverb
algorithm.
Noise Generator
With the
Carrier
wave selected on the OSCILLATOR panel, tap the
Wave
button
and change the
Synth Mode
to Subtractive. Now if you
Arrow Right
or tap

you’ll see:
