Envelope parameters: page 2
Control knob Parameter Range Description
1 AtkCurve Log (-64) > Lin (0) >
Exp (64)
Denes the curve for the attack segment.
2 DecCurve Log (-64) > Lin (0) >
Exp (64)
Denes the curve for the decay segment.
3 (blank) - -
4 RelCurve Log (-64) > Lin (0) >
Exp (64)
Denes the curve for the release segment.
5 Legato O, On When On, an envelope won’t reset unless all
notes have been released.
6 Reset O, On When On, an envelope is reset when
polyphony is exceeded. If Legato = On,
Reset is not available.
7 Freerun O, On When On, an envelope will always run from
Delay to the Sustain stage (note held) or
from Delay through the Release stage (note
released).
8 Env Loop O, 2-50, Innite Toggles the looping feature and denes the
number of times the envelope will loop.
Envelope curves
A logarithmic curve “picks up steam” as it goes:
During the attack segment it starts rising
slowly and accelerates upward. During the
decay and release segments it starts falling
slowly and accelerates until it reaches its
resting state.
An exponential curve is the opposite of a
logarithmic curve: During the attack segment
it starts rising quickly and its rate of change
slows as it nears the peak. During the decay
and release segments it starts falling quickly
and decelerates until it reaches its resting state.
A linear curve rises and falls at the same rate
throughout its duration. However, linear
changes seem less natural or “musical” to the
human ear than the other curves.
Legato
When sheet music uses the term “Legato”
it means to play a passage smoothly, with
no rests between the notes. Likewise, when
this parameter is set to On, the envelope
will not retrigger if previous voice has not
been released. This allows a lter envelope to
remain at its sustain stage when a series of
notes are played, for example, which can help
a solo or a bass line to be more expressive.
Reset
The Reset parameter is only available when
Legato is O. When Reset is On an envelope
will reset when a new note is played, even if
the previous note has not been released.
The dierence between Reset On and O is
easy to hear with a monophonic patch. But
with a polyphonic patch the behavior is more
obvious after the available polyphony has
been exceeded. You’ll need a sustain pedal for
the following example.
1. Set speaker/headphone levels low;
this could be loud.
2. Press [INIT] twice to initialize the patch
3. Access [FILTER 1] and set Type to HP
MS20
4. Set Cuto to 50, Resonance to 100, and
ENV1 amount to 64
5. Access [ENV 1] and set Attack and Decay
to ~1 second
6. Hold down the sustain pedal
7. Play 7 notes on the lowest C
8. Wait for the lter to reach the sustain
level for all 7 voices
