menu 3. envelope ADSR
welcome to menu 3 where we'll explore the
ADSR
envelope in FM synthesis. the envelope
is like a roadmap for the sound, determining how it evolves over time. here's a
breakdown of the different parameters:
attack
: determines how quickly the sound reaches maximum volume when a key is
pressed.
decay
: determines how quickly the sound drops from maximum volume to the
sustain level.
sustain
: determines the volume level that the sound will sustain at while a
key is held down.
release
: determines how quickly the sound fades out after a key is
released. additionally, we have the
total level
parameter, which sets the overall volume
of the operator. finally, the
rate or key scaling
is the degree to which the envelope
becomes narrower as the frequency becomes higher.
submenu 1:
you can control
attack rate
with left knob and
total level
with right knob
submenu 2:
control
decay rate
with left knob and
secondary total level a.k.a. sustain
with right knob
submenu 3 :
control
secondary decay rate
with left knob and
release rate
with right
knob
submenu 4:
control the
rate or key scaling
with the right knob
