Roland RD-600 - EFX Effect Types and Knob Assignments

to each knob
EFX provides the 40 effect types described below.
Some of the effect types are compound effects in
which two kinds of effects are linked together.
The RATE/SENS knob and the DEPTH/LEVEL knob
are assigned parameters suitable for the selected
effect type, as described below.
1. RESONANCE
This simulates the resonance that occurs when the
damper pedal is pressed.
RATE/SENS: Sensitivity
This adjusts the amount of the effect relative to how
far the pedal is pressed.
DEPTH/LEVEL: Level
This adjusts the amount of the resonance effect.
2. OVERDRIVE
This produces natural distortion similar to that pro-
duced by a vacuum-tube amp.
RATE/SENS: Drive
This sets the strength of the distortion.
DEPTH/LEVEL: Amp Type
This simulates the characteristics of four types of gui-
tar amp.
From a full-left knob setting, this will change through
four stages.
SMALL: a compact amp
BUILT-IN: a built-in amp
2-STACK: a large two-stack amp
3-STACK: a large three-stack amp
3. DISTORTION
This increases the odd-numbered harmonics to add
strong distortion to the original sound.
RATE/SENS: Drive
This sets the strength of the distortion.
DEPTH/LEVEL: Amp Type
This simulates the characteristics of four types of gui-
tar amp.
From a full-left knob setting, this will change through
four stages.
SMALL: a compact amp
BUILT-IN: a built-in amp
2-STACK: a large two-stack amp
3-STACK: a large three-stack amp
4. PHASER
This adds a phase-shifted sound to the original sound
to make the tone change over time, producing modu-
lation in the sound.
RATE/SENS: Rate
This sets the speed of the modulation.
DEPTH/LEVEL: Depth
This sets the depth of the modulation.
56
5. SPECTRUM
This is a type of filter, which creates a distinctive
sound by modifying the level at a specific frequency.
RATE/SENS: Band
Adjust the frequency at which the level will be adjust-
ed.
DEPTH/LEVEL: Level
Adjust the level of the frequency being controlled.
6. ENHANCER
Enhancer controls the overtone structure of the high
frequency range, adding sparkle to the sound and
improving the definition.
RATE/SENS: Sensitivity
This sets the depth to which the Enhancer is applied.
DEPTH/LEVEL: Mix
This sets the ratio at which the original sound is
mixed with the generated harmonics.
7. AUTO-WAH
This lets you obtain an Auto-Wah effect in which the
sound is changed cyclically by cyclic movement of a
filter.
RATE/SENS: Rate
This sets the speed of modulation of the wah effect.
DEPTH/LEVEL: Depth
This sets the depth of the modulation of the wah
effect.
8. ROTARY
This simulates an old-fashioned rotary speaker which
adds modulation to the sound by rotating the speak-
er. This is most effective when used with an organ
sound.
RATE/SENS: Speed
This switches the rotational speed of the rotary effect.
DEPTH/LEVEL: Separation
This sets the spatial width of the sound.
9. COMPRESSOR
This stabilizes the overall level by suppressing high
levels and boosting low levels.
RATE/SENS: Sustain Time
This sets the time over which a low-level signal is
boosted to a uniform volume.
DEPTH/LEVEL: Attack Level
This sets the force of attack when sound is input.
10. LIMITER
Whereas the Compressor acts on both low-level and
high-level signals, the Limiter compresses only high-
level signals that exceed a set level. You can eliminate
unwanted distortion by setting this to work only on
peak input.
