Contour Section
The envelope generator section is an
envelope generator used to dynamically
shape volume and and/or cutoff frequency. If
you're not familiar with the operation of
envelope generators, here's an overview:
When MG-1 Plus sees a gate voltage from a note, the contour generator outputs a
dynamically changing voltage, according to the settings of its stages. The
Rise Time
(i.e.
attack) stage defines how long it takes for the output voltage to rise from 0 to 5 volts. Once
the
Rise Time
reaches 5V, it moves to the
Sustain
phase if the
Sustain
switch is set to the
In
position and the holds at 5V until the key is released. If the
Sustain
switch is set to
Out
, it
immediately moves to the
Fall Time
stage. The
Fall Time
(i.e. decay and release) slider
defines the the length of time it takes for the voltage to fall back to 0V when the gate input
voltage is removed, i.e. when the key is released.
Rise Time slider
- Defines the length of time for voltage to rise from 0V to 5V when a key is
played.
Sustain
- When set to the
Out
position, following the
Rise
stage, the contour generator
immediately moves to the
Fall
stage. When set to the
In
position, the envelope holds at 5V
until as long as a key is held. When the key is released, it moves to the
Fall
stage.
Fall Time slider
- Defines the length of time for voltage to fall from full sustain level to 0V
when a key is released.
