Here, you can set whether or not LFO2 will re-trigger with every new note-on
or not. With set to ON, each note you play will reset the cycle of the
selected waveform to its leading edge. For example, with the triangle wave
selected, you would get this result:
MIDI NOTE ON
This is useful for certain types of modulation effects where you want the effect
to start at the same point in the modulation waveform for every note you play.
For example, if you are using the square wave, you may want it to always start
on the rising edge with each note you play. The same may apply for the
sawtooth and random waveforms.
However, there are occasions when you want the LFO to be free running in
the background. For example, on filter or panning sweeps where you want the
effect to be gradual as you play, you will want to switch to OFF to get
this result:
MIDI NOTE ON
Here, the modulation waveform will ignore incoming note-on messages and
will be rising and falling giving you a gradual sweep through whatever it is
applied to. This is particularly useful when triangle is selected and applied to
the filter(s) as you can re-create the old filter sweep effects of analogue synths.
There are no modulation inputs to LFO2.
You may use LFO2 for a number of things. As mentioned above, when LFO1 is tied up doing
vibrato via the modwheel, LFO2 may be used to affect things such as panning, filter sweep and
amplitude modulation. Of course, there is no reason why you shouldn’t use LFO2 for vibrato
either and mixing it with LFO1 as a source of vibrato can create some rich ensemble textures.
Many interesting things are possible when modulating LFO1 with this LFO - at extreme settings
you can make LFO1’s modulation speed up and slow down for special sound effects or synth
sounds but, if you’re trying to breathe some life into some dead string samples, for example,
you may like to use LFO2 to
slightly
modulate LFO1 thereby affecting the vibrato very subtly so
as to eliminate the inherent ‘cyclicness’ of LFO modulation. No doubt you will find variations of
your own.
