LFO 1
LFO stands for Low Frequency Oscillator. An LFO is an oscillator producing waveforms with a certain
pitch, just like Oscillator 1 and 2. The differences are two:
▼
The LFOs produce waveforms with very low frequencies.
▼
You never hear the actual output of the LFO. Instead the output from the LFO is used for modulating,
that is controlling other functions, like for example the main oscillator frequency (vibrato) or the filter
frequency (wah-wah).
Waveform
This is used to set the shape of the output from the LFO:
Triangle:
This is suitable for “normal vibrato” effects and for classic pulse width modulation.
Sawtooth:
This creates a ramp which can be used for example for auto-repeats when applied to the filter.
Random:
This adds random modulation to the destination. This is mainly useful for effect sounds.
Rate
This is used to set the frequency of the LFO, in other words “the speed of the vibrato”.
The rate can be controlled externally, via MIDI, see page 61.
Destination
This used to set which parameter the LFO should affect:
Osc 1+2:
This routes the LFO to the frequency of both oscillators, in equal amounts. Together with the
triangle waveform this creates traditional vibrato.
Osc 2:
This routes the LFO to the pitch of oscillator 2 only. This can for example be used together with
Sync (see page 39) to create a “pulsating” change in timbre.
Filter:
This routes the LFO to the Filter Frequency. This can for example be used for wah-wah effects (tri-
angle wave) and for auto repeating sounds (sawtooth wave).
P Width:
This routes the output of the LFO to the Pulse Width of both oscillators. For this to have any ef-
fect, pulse wave must of course be selected for at least one of the oscillators. This destination can be used
with an LFO triangle waveform to create a “chorus-like” sound, suitable for strings and pads.
Please note that this function operates relative to the Pulse Width setting. For optimal results, please
match the Pulse Width and LFO Amount settings (see below).
