Low-Frequency Oscillator (LFO)
Filterstation has a single low-frequency oscillator (LFO) for controlling the filters. The LFO can modulate the
frequency of either or both of the filters.
Shapes
The LFO has a selection of different wave shapes. The following shapes are available:
SINE - a sinusoidal wave which rises and falls smoothly, with no corners or sudden jumps.
TRIANGLE - a wave which moves up and down in straight lines, rising at the same speed that it falls.
RAMP UP - a wave which rises slowly from zero to its maximum value, then jumps back to zero.
RAMP DOWN – the opposite of RAMP UP: it jumps from zero to its
maximum value, then returns slowly to zero.
SQUARE – a wave which jumps between zero and its maximum value,
staying at both values for the same period of time.
33% PULSE – like the SQUARE wave, but it stays at the maximum
value for 1/3 of its total time and at zero for 2/3 of the time.
25% PULSE – like the SQUARE wave, but it stays at the maximum
value for 1/4 of its total time and at zero for 3/4 of the time.
SPIKE – this wave rises quickly from zero to the maximum value, and
then falls back to zero.
PATTERN 1-4 – these settings produce 16-step rhythmic patterns for
creating burbling filter sequences, trance-gate patterns, etc.
