Roland SC-88 Pro ❍Effects that affect the level (compressor type)

Low Gain -12 - +12 [17]

Adjust the gain of the low frequency range.

Hi Gain (High gain) -12 - +12 [18]

Adjust the gain of the high frequency range.

Level (Output level)	0 - 127 [20]
Adjust the output level.
13: Auto Pan	[01H, 26H]

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

Mod Wave (Modulation wave) Tri/Sqr/Sin/Saw1/Saw2 [1]

Select 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.

+Mod Rate (Modulation rate)	0.05 - 10.0	[2]
Adjust the frequency of modulation.
#Mod Depth (Modulation depth)	0 - 127	[3]
Adjust the depth of modulation.
Low Gain	-12 - +12 [17]

Adjust the gain of the low frequency range.

Hi Gain (High gain) -12 - +12 [18]

Adjust the gain of the high frequency range.

Level (Output level) 0 - 127 [20]

Adjust the output level.

❍Effects that affect the level (compressor type)

14: Compressor [01H, 30H]

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

R

Attack 0 - 127 [1]

Adjust the attack time of an input sound.

Sustain 0 - 127 [2]

Adjust 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	0/+6/+12/+18 [3]
Adjust the output gain.
Low Gain	-12 - +12	[17]
Adjust the low frequency gain.
Hi Gain (High gain)	-12 - +12	[18]
Adjust the high frequency gain.
+Pan (Output pan)	L63 - 0 - R63	[19]

Adjust the stereo location of the output sound. L63 is far left, 0 is center, and R63 is far right.

#Level (Output level)	0 - 127 [20]
Adjust the output level.
15: Limiter	[01H, 31H]

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

R

Threshold (Threshold level) 0 - 127 [1]

Adjust the volume at which compression will begin.

Ratio (Compression ratio) 1/1.5,1/2,1/4,1/100 [2]

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) 0 - 127 [3]

Adjust the time from when the volume falls below the Threshold Level until compression is no longer applied.

Post Gain	0/+6/+12/+18 [4]
Adjust the output gain.
Low Gain	-12 - +12 [17]
Adjust the low frequency gain.
Hi Gain (High gain)	-12 - +12 [18]
Adjust the high frequency gain.
