The envelope generator of the Jupiter-8V
8.2.3 The low frequency oscillator
The LFO (Low Frequency Oscillator – or LFO on the Jupiter-8V) possesses more or less
the same characteristics of the classic oscillator but it only produces frequencies lower
than 20 Hz. In other words, you won’t hear the pitch of its sound.
It will create a cyclic modulation on the setting to which it is connected. For example:
• If the sine waveform of an LFO modulates the volume of an amplifier, the sound
will increase in volume then disappear in a varying manner following the speed
(the frequency) of this LFO. This will produce a tremolo effect.
• A sine waveform on an LFO modulating the frequency of an oscillator would
produce a vibrato effect.
• With an LFO sine wave modulating the cut-off frequency of a lightly resonant low-
pass filter, you will obtain a “wah wah” effect.
