In many cases Normal and the Uni modes might not seem much different
from the audible effect, but sometimes its more handy to know that the LFO
will only change the modulation value in one direction (unipolar) as
opposed to its normal bipolar operation.
The Cut modes actually deliver a modified waveform and are unipolar.
The huge Freq (Frequency) dial determines the LFO's frequency. Above
the dial is a display which functions in two ways: usually it shows the
frequency in Hz or in Notes (when synced). When you click it you can
select either a synced tempo setting like for example 1/16
th
note or Off,
which lets you adjust the Frequency in Hz.
Right of the Frequency is the Symmetry parameter. It can be used to distort
the LFO waveform shape, as you might know it from oscillator waveforms.
The Smooth dial allows to gradually soften the LFO waveform which is
particularly useful when you apply Pulse, SH or Radom Pulse waveforms to
amplitude modulation (and sometimes filter modulation) as otherwise this
can result in unwanted audible clicking.
Note: Smooth does almost nothing on waveforms with low harmonics, so
its for example without effect on the Sine waveform.
the Delay and Attack dials. Please note that the Delay and Attack
parameters do not function if the LFO is set to Mono mode (because then
it’s a permanently running LFO).
The Phase parameter sets the point in the waveform cycle at which the
LFO starts when its triggered (by a Note being played). However, its much
more powerful:
Below the dial is a switch that allows you to set three LFO-Start-Modes:
Phase, Free-Run and Phase/Mono which will take a moment to explain in
