Roland JD-Xi Analog/Digital Synthesizer (Black) - Manual (Page 9)

Modulating the Sound (LFO)
LFO stands for Low-Frequency Oscillator. This is an
oscillator with a very low frequency. It can output
several different waveforms, including sine wave,
triangle wave, square wave, and sawtooth wave.
By using the LFO to modulate various aspects of the
audio signal, you can apply effects such as vibrato or
tremolo.
Waveform select knob
This selects the waveform of the LFO.
The waveform whose indicator is lit is selected.
S (Triangle wave), R (Sine wave), T (Sawtooth wave), U (Square wave),
W (Sample and Hold), RND (Random wave)
[Rate] knob
This determines the speed of the LFO.
[Depth] knob
This specifies the depth of the LFO.
[Destination] knob
This specifies what the LFO will affect.
The destination whose indicator is lit is selected.
Destination Explanation
Pitch Applying LFO to the pitch produces vibrato.
Filter Applying LFO to the filter produces a wah effect.
Amp Applying LFO to the amp produces tremolo.
NOTE
The LFO effect is not applied to the Drums part.
Adding Power and Spaciousness (EFFECTS)
“Effects” allow you to modify
or enhance the sound in
various ways, such as by adding
reverberation or delaying the
sound.
[Effects ON/OFF]

that order, and only the effects that are turned on will apply.
