Modulating Sounds-Adding Vibrato, Tremolo, Etc./Using Controllers To Change How Sounds Are Played (Lfo&Ctl) - Roland XP-60 Owner's Manual

Modulating sounds–Adding Vibrato,
Tremolo, etc.
Using controllers to change how sounds
are played (LFO&Ctl)
LFO1 Prm (LFO 1 parameter) display/LFO2 Prm
(LFO2 parameter) display
An LFO (Low Frequency Oscillator) causes change over a
cycle in a sound. Each Tone has two LFOs, and these can be
used to cyclically change the pitch, cutoff frequency and vol-
ume to create modulation-type effects such as vibrato, wah-
wah and tremolo. Both LFOs have the same parameters so
only one explanation is needed.
Waveform (LFO waveform)
Selects the waveform of the LFO. The selected waveform is
graphically displayed.
TRI: Triangle wave
SIN: Sine wave
SAW: Sawtooth wave
SQR: Square wave
TRP: Trapezoidal wave
S&H: Sample and hold wave
RND: Random wave
CHS: Chaos wave
Key Sync (LFO key sync)
Specifies whether you want the LFO cycle to start in sync
with the timing of a key press (ON) or not (OFF).
Rate (LFO rate)
Adjusts the modulation rate of the LFO waveform.
If you have selected CHS (chaos waveform) for
Waveform parameter, the Rate parameter setting has
no effect.
If you have set the Ext Sync parameter to CLK, this
parameter will indicate a note value in multiples of a
quarter note. The corresponding note value symbol is
also displayed. This allows you to set the Rate parame-
ter in terms of a note length in the sync tempo.
Ext Sync (LFO external sync)
Selects how the LFO is to be synchronized.
OFF: Unsynchronized.
CLK: Synchronizes the LFO delay time to the Patch Tempo
parameter setting (PATCH/Common/Common General) or
Perform Tempo parameter setting (PERFORM/Common/
Common) or sequencer's tempo clock.
[PATCH] [F5] (LFO&Ctl) [F1] (LFO1)/[F2] (LFO2)
Chapter 3. Creating your own sounds
If you want to use a fixed tempo in Patch mode, set the
Clock Source parameter (PATCH/Common/Common
General) to PATCH and set the desired tempo.
If you want to use the sequencer tempo clock in Patch mode,
set the Clock Source parameter (PATCH/Common/
Common General) to SEQUENCER.
If you want to use a fixed tempo in Performance mode
(Perform Tempo parameter setting), set the Clock Source
parameter (PERFORM/Common/Common) to PERFORM
and set the desired tempo.
If you want to use the sequencer tempo clock in Performance
mode, set the Clock Source parameter (PERFORM/
Common/Common) to SEQUENCER.
Fade Mode (LFO fade mode)
Selects how the LFO is to be applied.
ON-IN: The LFO will fade in after the key is pressed.
