shown in the LFO waveform display. A setting of “Free” means,
that the start phase is random.
•
Delay
: Controls the time before the Level LFO waveform is
faded in or out. Depending on the setting of
Fade
, it either
causes the Level LFO to start with maximum amplitude for the
time set by
Delay
before it is faded out, or to start with zero
amplitude before it is faded in.
•
Fade
: Controls the fade in or fade out of the Level LFO
waveform. When set to center, the Level LFO stays at its
maximum amplitude forever. When the parameter is set below
center, the Level LFO waveform is faded out after the time set
by
Delay
, when it is set above center, it is faded in after the
time set by
Delay
.
Pitch Envelope
This multistage
envelopes with up to 32
nodes is used to
modulate the pitch of a
tone generator (O1 to
O8, Noise as well as S1
and S2). For Filter 1 and 2
it is called Cutoff
Envelope and modulates,
was is says, the cutoff
frequency. Envelopes are
essential parts of any synthesizer. They are mostly used to change the
volume of a sound over time, which is essential for any sound from any
acoustic or electronic instrument. In this special case, this envelope
controls the pitch but you can freely assign it to other modules as well.
The
Copy/Paste
buttons lets you copy all settings from
this envelope and paste it to any other, regardless of its
Layer.
Click on the
Magnifying Glass
symbol in the upper right corner to
maximize the envelope curve display. Here you can find additional
parameters. To close the maximized view, click on the X symbol in the
upper left corner of the envelope window.
Basically, this envelope offers three time stages (nodes 1, 2 and 3) which
controls Attack, Decay and Release. Sustain is a time parameter and is
defined by the length of the played note that triggers the envelope.
• To add more stages (up to 32), double click on the line
between two numbers. A new stage number will be added
automatically. To delete a stage, double click directly onto the
corresponding number. Add more stages, if you need a more
precise control for modulations. Keep in mind that stages can
overlap, so that you cannot see them. Click and move a stage
breakpoint for a better overview.
• If you have setup other Pitch Envelopes for the same Layer, the
corresponding curve is shown as overlay within the current
envelope. This might be helpful when comparing envelopes.
•
Breakpoint
handle: Controls the time for the respective
envelope stage. These parameters can be adjusted by clicking
on the corresponding breakpoint handle and moving it in the
