The
(Delay)
–button is used to delay the start of the LFO’s. The delay range is between 0,015
sec and 5 sec. An example is the delayed start of a vibrato if a flute-alike sound.
Use the
(Rate)
–knob to set the frequency of the LFO’s. This means the speed of the
modulation. The LFO’s can be used up to audio frequency. This can lead to very interesting
sounds (try it out!)
The
(Waveshape)
–button lets you choose between the waveforms of the LFO’s. The
available waveforms are:
A
– triangle
A symmetrical ascending and descending waveform. Use
this for creating normal vibratos.
C
– ascending saw
Slow start and a sudden drop are the characteristics of
this wave. When the LFO frequency is low, this can be
used to create interesting filter sweeps.
B
– descending saw
Sudden start and slow decay. Can be used for reverted
echo effects.
D
– Square
Starts and drops abruptly. It’s good for tremolos and
many other things. Because this waveform almost
corresponds to on/off, it can also be used to cut up audio
signals or to make them rhythmic. (we’ll explain how it’s
done in chapter
Routing Elements
)
E
– Random
Random waveform. Lots of interesting effects can be
produced by this waveform. When routed to the filter
cutoff, it creates the well-known sample&hold effects. All
kinds of bubbling sounds are created with the help of this
setting. When turning up the frequency into audio range,
you’ll obtain some sort of low frequency noise signal.
Use the
(Trigger)
-button to define whether the LFO is
restarted at a zero-crossing every time a note-on command
is sent.
