Auto Pan; Compressor; Limiter - Roland SC-8820 Owner's Manual

Effects

13: Auto Pan

The Auto Pan effect cyclically modulates the stereo location
of the sound.

Mod Wave (Modulation Wave)
Tri/Sqr/Sin/Saw1/Saw2 [1 (40 03 03)]
Selects the type of modulation.
Tri: The sound will be modulated like a triangle
wave.
Sqr: The sound will be modulated like a square
wave.
Sin: The sound will be modulated like a sine
wave.
Saw1,2: The sound will be modulated like a
sawtooth wave. The teeth in Saw1 and
Saw2 point at opposite direction.

Saw1
+Mod Rate (Modulation Rate)
Adjusts the frequency of modulation.
#Mod Depth (Modulation Depth)
Adjusts the depth of modulation.
Low Gain
Adjusts the gain of the low frequency range.
Hi Gain (High Gain)
Adjusts the gain of the high frequency range.
Level (Output Level)
Adjusts the output level.
Effects that affect the level (compressor type)

14: Compressor

The Compressor flattens out high levels and boosts low
levels, smoothing out unevenness in volume.

Sustain
Adjusts the time over which low level sounds are boosted
until they reach the specified volume.
Increasing the value will shorten the time. When the value
is modified, the level will also change.
Post Gain
Adjusts the output gain.
Low Gain
Adjusts the low frequency gain.
Hi Gain (High Gain)
Adjusts the high frequency gain.
+Pan (Output Pan)
Adjusts the stereo location of the output sound. L63 is far
left, 0 is center, and R63 is far right.
#Level (Output Level)
Adjusts the output level.

15: Limiter

The Limiter compresses signals that exceed a specified
volume level, preventing distortion from occurring.

R
Threshold (Threshold Level)
Adjusts the volume at which compression will begin.
Ratio (Compression Ratio)
This adjusts the compression ratio for signals that are
louder than the Threshold Level. 1/100 is the highest
compression ratio, and the output level will decrease.
Release (Release Time)
Adjusts the time from when the volume falls below the
Threshold Level until compression is no longer applied.
Post Gain
Adjusts the output gain.
Low Gain
Adjusts the low frequency gain.
Hi Gain (High Gain)
Adjusts the high frequency gain.
+Pan (Output Pan)
Adjusts the stereo location of the output sound. L63 is far
left, 0 is center, and R63 is far right.
#Level (Output Level)
Adjusts the output level.
