PROG P5: LFO

Each of the Oscillators 1, 2 has two LFOs, which you can use
to modulate the filter, amp, pitch, and many other
parameters.
The two Oscillators also share a single Common LFO,
similar to the global LFO on some vintage analog synths.
These pages let you set up all of the parameters for all five
LFOs.
5–1: OSC1 LFO1
5–1a
5–1b
5–1c
This page has all of the controls for the first LFO of
Oscillator 1. For instance, you can:
• Select the LFO's basic waveform, and modify it with the
Shape parameter.
• Control the LFO's frequency, and assign AMS
controllers to modulate the frequency.
• Use the Key Sync parameter to choose whether the LFO
runs separately for each voice, or is synchronized across
all of the voices
• Use the Fade and Delay parameters to control how long
the LFO waits to start after note-on, and whether it starts
abruptly or fades in slowly.
• Set the LFO to sync to MIDI tempo.
5–1a: OSC 1 LFO 1
Waveform
[Triangle...Random6 (Continuous)]
This selects the basic LFO waveform, as shown in the
graphic below.
Most of the waveforms should be self-explanatory, but a few
will benefit from more details:
Guitar is intended for guitar vibrato, and its shape is
specifically tuned for this purpose. The waveform is
positive-only, so that when used for pitch, it will only bend
up, and not down.
Random1 (S/H) generates traditional sample and hold
waveforms, in which the level changes randomly at fixed
intervals of time.

Random2 (S/H) randomizes both the levels and the timing.
Random3 (S/H) generates a pulse wave with random
timing. It's the opposite of traditional sample and hold; the
timing varies, but the levels don't.
Random4–6 (Continuous) are smoothed versions of
Random 1–3, with ramps instead of steps. You can use them
to create more gentle random variations.
Phase
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.
5–1
Menu
Freq (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.

Stop
On (checked): Instead of the LFO operating normally, it will
ignore the Freq setting. The LFO will maintain the initial
value (determined by the combination of Waveform, Phase,
Shape, and Offset) until the note-off.
Since the value will change only at note-on, using a Random
waveform will produce a fixed value that changes randomly
at each note-on (or at the first note-on).
Off (unchecked): The LFO will operate normally.
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
