LFO2
Pressing the
key will take you to the second LFO page:
This is a simpler LFO for auxiliary modulation purposes. Whilst LFO1 is normally used for
vibrato via the modwheel or pressure, LFO2 can be used for secondary modulation
purposes such as filter sweeps, amplitude modulation, panning, etc.. As usual, the
program name is displayed in the top right hand corner. The parameters are as follows:
This selects the modulation waveform. The choices are:
TRIANGLE (
) - This gives a rising and falling effect. At around a setting
of 75, this can be used for vibrato but can be assigned anywhere you like
and can be used for filter sweeps, panning, amplitude modulation and
slow pitch sweeps. This is a ‘bi-polar’ modulation waveform that ‘rotates’
around the note you are playing to give a natural vibrato effect.
0
SAWTOOTH ( ) - This waveform is used mostly for special effects. It rises
slowly and falls abruptly. This is a ‘uni-polar’ waveform that jumps between
the held note and the modulation level set at the destination. It can be
inverted at the modulation input stages of each destination to give
downward sweeps.
0
SQUARE ( ) - This gives stepped ‘up and down’ effect. When applied to
pitch it can be set to give trills or large octave jumps. This is a ‘uni-polar’
waveform that jumps between the held note and the modulation level set
at the destination. Like the sawtooth wave, it can be inverted at the input
stages of each destination.
0
RANDOM (
) - This gives a totally random stepped waveform and is
suitable for special effects. Like LFO1’s RANDOM waveform, it can be
used to create the classic ‘sample and hold’ effect found on analogue
synthesisers.
However, the random waveform provided by LFO2 has some other
possibilities.
