LFO1
Pressing will give you this screen display:
This is the page used for setting up LFO1. Again, the program name is shown at the top right of
the screen and other programs may be selected for editing if you wish. The parameters for
LFO1 are as follows:
This allows you to select from three waveforms. They are:
TRIANGLE ( ) - This gives a rising and falling effect. At around a setting of
75, this would normally 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.
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.
0
RANDOM ( ) - This gives a totally random, stepped waveform and is
suitable for special effects. The effect that immediately springs to mind, of
course, is the classic ‘sample and hold’ effect found on analogue synthesisers
- by routing this to pitch you can create random pitch effects suitable for, say,
creating computer effects, especially when the LFO speed is set quite fast.
When applied to the filter(s), you can create many interesting random tone
change effects. You can even use this wave to control LFO1’s rate so that not
only will pitch, tone or whatever modulation input this LFO is assigned to be
random but the speed of modulation will change randomly.
