LFO RATIO
The LFO Ratio controls the shape of the basic LFO waveform. A central value of 50% keeps the
waveform symmetrical, so the Tri/Saw waveform is a pure Triangle, and the Rectangle wave is a pure square
wave. With the Rectangle wave, the Ratio value is the pulse width, ranging for 1% to 99%. With the Tri/Saw
waveform, a Ratio of 1% provides a Saw Down waveform, and a value of 99% is a Saw Up waveform as
shown below.
Ratio = 1% Ratio = 50% Ratio = 99%
LFO DEPTH
The LFO Depth controls the amount of LFO modulation applied to the output. The range is from 000
(off) to 127 (maximum).
LFO OFFSET COARSE
The LFO offset allows the LFO to be centralised around zero (value of 000) for even positive and
negative swings, or biased in either polarity. For example, vibrato would need to be centralised, but Tremolo
would be only positive polarity. The range is -127 through to 000 to +127.
Offset = -127 Offset = 000 Offset = +127
