SUBTRACTOR SYNTHESIZER293
LFO Section
LFO stands for Low Frequency Oscillator. LFO’s are oscillators, just like Osc 1 & 2, in that they also generate a wave-
form and a frequency. However, there are two significant differences:
• LFOs only generate waveforms with low frequencies.
• The output of the two LFO’s are never actually heard. Instead they are used for modulating various parameters.
The most typical application of an LFO is to modulate the pitch of a (sound generating) oscillator, to produce vibrato.
Subtractor is equipped with two LFO’s. The parameters and the possible modulation destinations vary somewhat be-
tween LFO 1 and LFO 2.
LFO 1 Parameters
Waveform
LFO 1 allows you to select different waveforms for modulating parameters. These are (from top to bottom):
Destination
The available LFO 1 Destinations are as follows:
|
Waveform
|
Description
Triangle This is a smooth waveform, suitable for normal vibrato.
Inverted Sawtooth This produces a “ramp up” cycle. If applied to an oscillator’s frequency, the pitch would sweep up to a set point
(governed by the Amount setting), after which the cycle immediately starts over.
Sawtooth This produces a “ramp down” cycle, the same as above but inverted.
Square This produces cycles that abruptly changes between two values, usable for trills etc.
Random Produces random stepped modulation to the destination. On some vintage synths, this is called “sample & hold”.
Soft Random The same as above, but with smooth modulation.

Destination

Description
Osc 1&2 Selecting this makes LFO 1 control the pitch (frequency) of Osc 1 and Osc 2.
Osc 2 Same as above, but for Osc 2.
Filter Freq Selecting this makes the LFO 1 control the filter frequency for Filter 1 (and Filter 2 if linked).
FM Selecting this makes the LFO 1 control the FM Amount parameter. Both oscillators must be activated for this to
have any effect.
Phase Selecting this makes the LFO 1 control the Phase Offset parameter for both Osc 1 and 2. Note that Phase Off-
set Modulation (Subtraction or Multiplication) must be activated for this to have any effect.
Osc Mix Selecting this makes the LFO 1 control the oscillator Mix parameter.
