2. Select the Waveform parameter.
3. Use the Inc or Dec
the different waveforms, and look at their shapes
in the graphic display.
There are a number of waveforms to choose from. Each
are suited to different applications:
• Triangle and Sine are the classic LFO shapes for
vibrato, tremolo, panning, and filter wah effects.
• Square is useful for gated filter and amp effects,
and creates a police siren effect when modulating
pitch.
• The Guitar waveform is designed especially for
guitar vibrato, since it bends only upwards from
the base value.
• Saw and Exponential Saw Down are good for
rhythmic filter and amp effects.
• Random 1 (S/H) creates the classic sample‐and‐
hold effect, which is great for modulating a
resonant filter.
4. After looking at the different waveforms, select
Triangle.
5. Select the Shape parameter, and use the VALUE
slider to move through its different settings, from ‐
99 to +99.
Notice how the shape of the waveform becomes more
curved, and how ‐99 emphasizes the lower part of the
shape, and +99 emphasizes the upper part.
6. Select the Start Phase parameter, and use the
VALUE slider to sweep through its range of
values.
Notice how the waveform shifts from side to side.
Among other things, this lets you offset the LFOs from
one another in time, which can create interesting
organic effects.
7. Use the Frequency parameter to set the speed of
the LFO.
8. Use the Fade and Delay settings to control the way
the LFO sounds at the beginning of the note.
For more information on LFOs, see "Program P5: LFO"
on page 92 of the Parameter Guide.
All of these parameters control the way that the LFO
itself works. In order for the LFO to actually affect the
sound, you can use the dedicated LFO routings on the
Filter, Pitch, and Amp pages, or use the LFOs as AMS
sources for a wide variety of parameters.

Frequency Modulation
AMS can be used to vary the LFO speed. This lets you
change the LFO speed by operating a controller, or by
the EG or Keyboard Track settings.
MIDI/Tempo Sync.
If MIDI/Tempo Sync is checked, the Frequency
setting will be ignored, and the LFO will synchronize
to the system tempo, as set by the TEMPO knob or
external MIDI clocks.
This lets you produce vibrato, wah, auto‐pan, or
tremolo effects that lock to the Drum Track, KARMA,
Wave Sequences, the internal sequencer, or external
MIDI sequencers.
EGs (Envelope Generators)
An envelope creates a modulation signal by moving
from one level to another over a specified time, and
then moving to another level over another period of
time, and so on.

The HD‐1 includes three EGs, for Pitch, Filter, and
Amp. These produce time‐varying changes in pitch,
tone, and volume respectively. They can also be used to
modulate a number of other Program parameters via
AMS.
