LFO 1 & LFO 2

Low Frequency Oscillator

Conventional instruments exhibit more `life' and variation in tonal character than electronic instruments due to the way in which they are played. For example, string instruments and woodwind instruments can exhibit marked tremolo and/or vibrato due to variations in the bowing or blowing. The keyboard of a synthesiser provides a relatively inflexible and expressionless means of playing that does not allow these nuances to be introduced into the sound, and in order to make the sound more `lively' amplitude and frequency modulation must be introduced using LFOs and noise sources.

LFO 1 and LFO 2 each provide two low-frequency waveforms.


  • Frequency (Square & Triangle) - <0.01Hz - >20Hz


  • Square and Triangle outputs - 10V peak-to-peak centred around 0V
