306 Chapter 21 EXS24 mkII
LFO Parameters
The EXS24 mkII includes three LFOs (low frequency oscillators) which can be used as
modulation sources. This section explains their parameters.
LFO 1 EG
This knob allows LFO 1 to be faded out (when the knob is pointing inside the Decay
area) or faded in (when the knob is pointing in the Delay area). In the centered position
(which can be set by clicking on the small 0 button), the LFO intensity is constant.
LFO 1 Rate
This is the frequency of LFO 1. It can be set in note values (left area), or in Hertz (right
area). In the centered position (which can be set by clicking on the small 0 button), the
LFO is halted, and generates a constant modulation value at full level (DC = Direct
Current).
Waveform for LFO 1 and LFO 2
These radio buttons allow you to select the waveform type used by LFO 1 and LFO 2,
respectively. A selection of Triangle, falling and rising Sawtooth, Square up and Square
down, a random stepped waveform, and a smoothed random waveform is available for
each LFO.
LFO 1 is a polyphonic LFO with key synchronization. This means that when LFO 1 is
used, each voice of the EXS24 has its own discrete LFO. When a note is played, the LFO
corresponding to that voice starts its cycle. This scheme means that the LFO cycles of
each voice played are not synchronous, and operate independently of each other. This
opens up a range of modulation possibilities. As an example—the LFO of one voice
could generate the maximum modulation value, while the LFO assigned to another
voice could output its minimum value. This extremely flexible approach can result in
some very lively modulations.
In contrast, LFO 2 is a monophonic LFO without key synchronization. This means that
LFO 2 runs continuously, and is not restarted by the triggering of a new note. All voices
are modulated by the sole LFO, so the degree of modulation at any given time is the
same for all voices. This results in a rather synthetic-sounding modulation.
Use these different characteristics to tailor the sound to your needs.
