Overview
Overview
The effect section of the
and two insert effects per timbre, and one master effect
for the entire program. You can use the EQ and insert effects to create the sound of each timbre, and use the master effect to add overall spatial processing.
For each of the insert effects and master effect, you can
choose one of thirty types of full-digital effect. The types
of effects are grouped in the following categories.
01–10 Filter and dynamics effects such as EQ and compressor
11–19 Reverb, early reflection, and delay
20–30
Pitch and phase modulation effects such as chorus and
phaser, rotary speaker, and pitch shifter
About the effect inputs and outputs
The insert effects and master effects are stereo-in/stereo-out. The Dry signal (the direct, unprocessed sound)
of the “Dry/Wet” balance will simply pass through the
stereo input as a stereo output. The way in which the
Wet signal (the sound processed by the effect) is output
will depend on the type of effect, and the possible configurations are shown below.

About the delay time
TimeRatio
For delay effects, the actual delay time is determined by
multiplying the delay time with the “TimRatio (TimeRatio).” Here are some examples.
• “BPM Sync”: Off, “L Delay”: 800 ms, “R Delay”: 400
ms, “TimRatio”: 50% settings will produce an actual
delay of 400 ms for the L-channel and 200 ms for the
R-channel.
• “BPM Sync”: On, “L Delay”: 1/4, “R Delay”: 1/8,
“TimRatio”: 50% settings will produce an actual
delay of an 8th note for the L-channel and a 16th
note for the R-channel.
Delay time for the insert effects
Broadly speaking, there are two types of effect for which
you can specify a delay time.
• Delay effects
• Modulation effects such as chorus that internally
use a fixed delay time
If you use such an effect in the two insert effects, the delay time of the effects can be set for a maximum of 1 seconds for each timbre.
Here are some examples.
• Insert effect 1 uses S.Delay (Stereo Delay,) and insert
effect 2 uses S.APnDly (St.Auto Panning Delay.) 500
ms of delay time is assigned to each effect.
Wet
In the block diagram given for each effect in the pages
that follow, the input/output configuration is listed in
the upper left of the diagram.
In order to obtain the best audio quality, use 12. Amp
page “Level,” 7. Mixer page “OSC1 Lvl,” “OSC2 Lvl,”
and “Noise Lvl” to adjust the input level to the insert effect and master effect, and set the “Trim” of each effect
to the maximum level that does not cause clipping. Then
use the “Dry/Wet” and “Output Level” of each effect to
adjust the output level of the effect.
Mono In - Stereo Out
Stereo In - Stereo Out
Some effect types do not have a “Trim” or “Output
Level” parameter.
There is no input level meter that indicates the input level to the effect. If the input level is insufficient, the S/N ratio will be degraded. If the input
level is excessive, clipping may occur.

Controlling the effect parameters
On the R3 you can assign one parameter each from insert effects 1 and 2 and the master effect (a total of three
parameters) to knobs [1–[4] and control these parameters while you perform.
Before you assign a parameter to a knob, you must first
select one parameter from each effect and specify this
parameter as the “Fx Knob” in the effect parameter settings (
☞
R3 owner’s manual p.49). After you’ve made
this setting, you can use the Shift function Knob Assign
to select IFx1Knob or IFx2Knob etc., and use the knob to
control the parameter that you assigned in “Fx Knob”
(
☞
R3 owner’s manual p.80).
Synchronizing the LFO 1/2 rate or the delay time of the delay effect to the arpeggiator tempo
You can synchronize the LFO 1/2 rate or the delay time
of the delay effect to the arpeggiator tempo. (When
“BPM SYNC”=ON)
Example 1. LFO1
16. LFO1 page “BPM Sync” (knob [3]): ON
16. LFO1 page LFO1 “SyncNote” (knob [4]): 1/4
In this case, one LFO cycle will occupy the same time as
one quarter note.
How “SYNC NOTE” and “RESOLUTION” settings correspond
to note values
The following table shows how LFO or delay effect
“SyncNote” settings and 33. Arpeg-B page “Resolutn”
settings correspond to note values.
The parameters will function according to the tempo
specified by [TEMPO] knob and the note value corresponding to its setting.

1. S.Comp
(Stereo Compressor)
This effect compresses the input signal to regulate the
level and give a “punchy” effect. This is useful when applied to sounds that have a strong attack.
If using this for the master effect, you can link the left
and right channels or make them operate independently.
Attack [000.1…500.0ms]

With L/R individually, the left and right channels control the Limiter individually.
When using this effect type for an insert effect, this
parameter is fixed at LR Mix.
Sens (Sensitivity) [001…127]
The “Sens” parameter sets the sensitivity of the compressor. If this parameter is set to a higher value, lower
level sounds will be boosted. With a higher Sensitivity,
the overall volume level is higher. To adjust the final
volume level, use the “Output Level” parameter.

2. S.Limit
(Stereo Limiter)
The Limiter regulates the input signal level. It is similar
to the Compressor, except that the Limiter compresses
only signals that exceed the specified level to lower unnecessary peak signals. If using this for the master effect,
you can link the left and right channels or make them
operate independently.

Mod Src (Modulation Source) [LFO, Ctrl]
Selects the modulation source that will control the cutoff
frequency. If you set this to LFO, the internal LFO will
modulate the cutoff frequency. If you set this to Ctrl, the
control source selected by “Ctrl Src” will control the cutoff frequency.
Mod Int (Modulation Intensity) [–63…+63]
Adjusts the depth of modulation applied by the modulation source (“Mod Src”).
Response (Modulation Response) [000…127]
Adjusts the response of the modulation effect.
A setting of 0 produces slow response.
LFO Sync (LFO BPM Sync) [Off, On]
Specifies whether the internal LFO cycle will synchronize to the tempo set by the [TEMPO] knob or by MIDI
clock.This parameter will be displayed and can be set if
“Mod Int” is LFO.
If this is Off, the LFO will operate at the cycle specified
by “LFO Freq.”
If this is On, the LFO will synchronize to the tempo or
MIDI clock.
In the 42. MIDI page “Clock” setting is Internal,
the LFO will synchronize to the tempo specified
by the [TEMPO] knob. If the setting is External, the
LFO will synchronize to the MIDI clock received
from an external MIDI device.
LFO Freq (LFO Frequency) [0.01…100.0Hz]
Sets the LFO speed. This parameter This parameter will
be displayed and can be set if “Mod Src” is LFO and
“BPM Sync” is Off.
Increasing this value will result in a faster frequency.
If this parameter is assigned to “Fx Knob,” the assignment will change to SyncNote if you turn
“BPM Sync” on. In the same way, setting “Mod
Src” to Ctrl will cancel this (assign it to Off), and
the knob will have no effect.
SyncNote (LFO SyncNote) [8/1…1/64]
Sets the internal LFO frequency as a proportion of the
tempo set by the [TEMPO] knob if “Mod Src” is LFO and
“BPM Sync” is On. The length of the specified value
(note value) relative to the tempo will be one cycle of the
LFO. For example if this is 1/4, one cycle will occupy
one quarter note.
If this parameter is assigned for “Fx Knob,” turning “BPM Sync” On will switch the assignment to
Sync Note. In the same way, setting “Mod Src” to
Ctrl will cancel this (assign it to Off), and the knob
will have no effect.
LFO Wave (LFO Waveform)

Specifies how the LFO will be reset at note-on if “Mod
Src” is LFO.
With Off, the LFO phase will not be reset when note-on
occurs.
Note on
With Timbre, the first note-on from a condition of no
keys being pressed will reset the LFO to the phase specified by “IniPhase,” and modulation will be applied at
that phase even if subsequent note-ons occur.

When “Mod Src” is set to Auto will select an auto-wah
that sweeps according to envelope changes in the input
signal level. Auto-wah is frequently used for funk guitar
parts and clav sounds.
When “Mod Src” is set to LFO, the effect uses internal
LFO to sweep in cycle.
When “Mod Src” is set to Ctrl, you can control the filter
directly via the modulation source in the same way as a
wah pedal.
Mod Int (Modulation Intensity) [–63…+63]
Adjusts the depth of the modulation produced by the
modulation source (“Mod Src”).
Response (Modulation Response) [000…127]
Adjusts the response of the modulation effect. A setting
of 0 produces the slowest response.
Env Sens (Envelope Sensitivity) [000…127]
When “Mod Src” is set to Auto, sets the sensitivity of
auto-wah. Increase the value if the input signal is too
low to sweep. Reduce the value if the input signal is so
high that the filter is stopped temporarily.
EnvShape (Envelope Shape) [–63…+63]
When “Mod Src” is set to Auto, this parameter determines the sweep curve for auto-wah.
