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.
