rich texture to ensemble sounds when being used for vibrato. When
is set to OFF, all LFO’s are in sync. This latter option is
probably more suited to use with synthesiser effects. You will find that
slower LFO speeds are possible with set to off.
The three fixed parameters for setting up LFO1 are:
This sets the rate of LFO1. This is variable between very slow (01) for such
effects as auto panning and filter sweeps and fast (99) for vibrato and
other effects.
This sets the output level of LFO1. This acts as a master LFO modulation
control for all destinations that have LFO1 routed to them. In this way, if
you wish to change the modulation level going to
all
destinations easily,
simply change this parameter. The range is 0-99.
NOTE: You may find that nothing happens when you route LFO1 to a destination and set
a modulation level at the destination’s input. This will be because LFO1’s depth is set to
00. This may seem a strange default at first but the reason is to do with the use of the
modwheel for vibrato. In order to be able to have the modwheel for vibrato as an
immediate effect, the LFO depth needs to be at 00 otherwise, there will be constant LFO
modulation of pitch. It is only when you are using LFO1 to apply a constant vibrato or for
something other than vibrato in specialist applications that you will need to specifically set
the depth control here.
This parameter sets the time it takes for the LFO1 effect to take place
after a note-on. At 00, the effect will be instantaneous but at 99 the effect
of LFO1 to take effect will be delayed. I.e:
NOTE ON
The three ‘VARIABLE’ fields apply to the modulation inputs of LFO1. Although not
specifically named, they relate to the parameters directly to their left - i.e. ,
and . The default for these parameters is so that you may affect speed, depth
and delay according to keyboard position, thereby emulating the fact that, for example,
high violins’ vibrato is often slightly faster, deeper and less delayed than low cellos or
contrabasses. These parameters allow you to create quite rich orchestral textures where
vibrato is never constant across the keyboard range.
Of course, you may select other modulation options for these inputs. Here are a few
ideas:
• Using LFO1 as an assignment to control its own rate will change the symmetry of the
waveform and you can use this to create new modulation waveforms (i.e. using a
square wave to modulate itself will create an asymmetric pulse wave). Using LFO1 to
modulate its own output level does create an effect but this can best be described as
subtle! Applying LFO1 to modulate its own delay is also very subtle to the point that,
with the exception of very slow sweeps, you probably won’t hear anything!
• Applying a slow LFO2 to speed will give a gradual speed up and slow down of LFO1
rate. This can be used for special effects, especially in synth sounds - for example,
