CHAPTER 7
The Parameters
LFO Section
(Encoder)
LFO 1
RATE
Determines the speed or rate of the LFO. In pol-
yphonic sounds, the manually selected RATE
value deviates slightly from voice to voice to liv-
en up the sound of the LFOs, which also oscil-
late polyphonically. When the LFO is synced up
to the master clock, the desired note value is
selected via the RATE knob.
If LFO clock is set to anything but OFF, the rate
knob will choose the clock.
SHAPE
Determines the waveshape of the LFO. You can
select from a sine, triangle, sawtooth, pulse
wave, a stepped random modulation (S&H;
short for Sample & Hold) or a smooth random
modulation (S&G; short for Sample & Glide). Al-
ternatively choose from a selection of 64 static
waveforms (WAVE 1-64)
CONTOUR
By LFO Contour you can now bend or ”morph”
(almost) all the LFO waveforms. A brief survey
of the LFO Contour options for the different
LFO modes follows:

- SINE Contour morphs from sine to a triangle
wave (Contour to the left) or to a square wave
(Contour to the right).
- TRIANGLE Contour morphs from a triangle
to a declining (Contour to the left) or ascend-
ing sawtooth (Contour to the right).
- SAWTOOTH Contour morphs from a linear
declining sawtooth or decay to any exponen-
tially declining decay(Contour to the left) or to
a square (Contour to the right).
- SQUARE C o n t o u r m o d u l a t e s t h e p u l s e
width of the square wave.
KEY FOLLOW
Controls the intensity of the KEY FOLLOW
function - i.e. the rate at which the LFO follows
the pitch of a played note. At a value of 0, KEY
FOLLOW is deactivated. At a value of 127, the
rate doubles with each octave.
