Random4–6 (Continuous) are smoothed versions of Ran‐
dom 1–3, with ramps instead of steps. You can use them to
create more gentle random variations.
Frequency
This controls the speed of the LFO, before any modulation.
Higher values mean faster speeds, as shown in the table
below.
By using AMS modulation, you can also get speeds much
faster and much slower than are available through this basic
setting.
Frequency Value Frequency in Hz
00 0.014 Hz
10 0.112 Hz
20 0.422 Hz
30 0.979 Hz
40 1.79 Hz
50 2.84 Hz
60 4.14 Hz
70 5.69 Hz

90 9.53 Hz
99 26.25 Hz
99 + Fine 99 32 Hz
Start Phase [–180...+180, RND (Random)]
This controls the phase of the waveform at the start of the
note, in steps of 5 degrees.
If "Key Sync" is Off, the Start Phase will apply only to the
first note of the phrase.
Shape
Shape adds curvature to the basic waveform. As you can see
in the graphic below, this can make the waveforms either
more rounded or more extreme. It can also be useful to
emphasize certain value ranges, and de‐emphasize others.
For example, let's say that you are using a triangle LFO to
modulate filter cutoff. If Shape emphasizes the high value
range, the filter will spend more time at the higher frequen‐
cies. If it emphasizes the low range, the filter will spend
more time at the lower frequencies.

Shape = 0 (original waveform)
Shape = +99
Shape = –99
Note: Shape does not affect the Square and Random3 wave‐
forms, since their values are always either +99 or –99. When
these are selected, Shape is grayed out.
OSC 2
Here you can specify the LFO1 and LFO2 waveforms for
oscillator 2.
[00...99]
The parameters are the same as the LFO1 and LFO2 settings
for oscillator 1 ( "OSC 1" on page 50).
Waveform
This selects the basic LFO waveform.

This controls the speed of the LFO, before any modulation.

This controls the phase of the waveform at the start of the
note, in steps of 5 degrees.

Common
This is a single, Common LFO, global for all voices in the
Program–like the modulation LFOs in some vintage analog
synths.
Waveform
This selects the basic LFO waveform.

[–99...+99] Frequency
This controls the speed of the LFO, before any modulation.

Start Phase
The Reset AMS, described above, lets you reset the Com‐
mon LFO. This is the phase from which the LFO will start
when it is reset.
Shape
Shape adds curvature to the basic waveform.
