[F5] LFO (Low Frequency Oscillator)
This display gives you a comprehensive set of controls over the LFO for each individual Element. The LFO can be used to create vibrato, wah, tremolo and
other special effects, by applying it to the pitch, filter and amplitude parameters.

saw (sawtooth wave)
Determines the speed of the LFO waveform. The higher the value, the faster the speed.
Settings: 0 ~ 63
Determines whether or not the LFO is reset each time a note is played.
Settings: off, on

Determines the delay time between the moment you play a note on the keyboard and the moment the LFO
comes into effect. A higher value results in a longer delay time.
Settings: 0 ~ 127
Determines the amount (depth) by which the LFO waveform varies (modulates) the pitch of the sound.
The higher the value, the greater the amount of pitch modulation.
Settings: 0 ~ 127
Determines the amount (depth) by which the LFO waveform varies (modulates) the Filter Cutoff frequency. The
higher the value, the greater the amount of filter modulation.
Settings: 0 ~ 127
Determines the amount (depth) by which the LFO waveform varies (modulates) the amplitude or volume of the
sound. The higher the value, the greater the amount of amplitude modulation.
Settings: 0 ~ 127
Determines the amount of time for the LFO effect to fade in (after the KeyOnDelay time has elapsed).
A higher value results in a slower fade-in.
Settings: 0 ~ 127
Determines the Equalizer Type. This synthesizer features a wide selection of various equalizer types, which can
be used not only to enhance the original sound, but even completely change the character of the sound. The
particular parameters and settings available depend on the specific Equalizer Type that is selected.
Settings: EQ L/H, P.EQ, boost6, boost12, boost18, thru
EQ L/H (Low/High) ................ This is a "shelving" equalizer, which combines separate high and low frequency bands.
P.EQ (Parametric EQ) ............ The Parametric EQ is used to attenuate or boost signal levels (gain) around the Frequency. This
type features 32 different "Q" settings, which determine the frequency band width of the equalizer.
boost6 (boost 6dB)/boost12 (boost 12dB)/boost18 (boost 18dB)
These can be used to boost the level of the entire signal by 6dB, 12dB and 18dB, respectively.
thru ........................................ If you select this, the equalizers are bypassed and the entire signal is unaffected.
