09:Dynamic Processor (Stereo Dynamic Processor)

A comp/limiter, enhancer, 3-band equalizer, and noise suppressor are connected in series.

Comp/Limiter is able to use as a compressor, which controls inconsistencies in sound levels by suppressing high sound levels while lifting weaker signals, or as a limiter that prevents the signal from reaching exceedingly high levels.

Enhancer regulates the high-end overtones, clarifying the sound and the sound contour.

3-Band Equalizer works in three frequency ranges: Low, Mid, and High. You can set the frequencies and boost or cut the level.

Noise Suppressor leaves the original sound unmodified, but mutes only the noise during the silent intervals.

L	Comp/			Enhancer	3-Band	Noise
R	Limiter				EQ	Suppressor
Parameter			Value		Description
Comp Sw			OFF, ON		Turns the comp/limiter on/off.
Comp Thresh-			-60–0 dB		Sets the volume level at which
old #1					the compression begins.
Comp Attack			0–127		Sets the time after the sound vol-
					ume is crossed the compressor
					threshold until compression be-
					gins.
Comp Release			0–127		Specifies the time from when the
					volume drops below the com-
					pressor threshold until com-
					pression is no longer applied.
Comp Ratio		1.5:1, 2:1, 4:1,			Sets the “source sound:output
		100:1			sound” compression ratio.
Comp Gain			-60– +12 dB		Output gain
Enhan Sw			OFF, ON		Turns the enhancer on/off.
Enhan Sens			0–127		Sensitivity of the enhancer
Enhan Frequen-			0–127		Sets the lower limit of the fre-
cy					quencies to which the enhance-
					ment effect is added.
Enhan Mix Lev-			0–127		Level of the overtones generated
el					by the enhancer
Enhan Level			0–127		Volume of the enhancer sound
EQ Low Freq			50–4000 Hz		Frequency of the low range
EQ Low Gain			-15– +15 dB		Gain of the low range
EQ Mid Freq			50–20000 Hz		Frequency of the middle range
EQ Mid Q		0.5, 0.7, 1.0, 2.0,			Gain of the middle range
		4.0, 8.0			Set a higher value for Q to nar-
					row the range to be affected.
EQ Mid Gain			-15– +15 dB		Gain of the middle range
EQ Hi Freq			2000–20000 Hz		Frequency of the high range
EQ Hi Gain			-15– +15 dB		Gain of the high range
NS Sw			OFF, ON		Turns the noise suppressor on/
					off.
NS Threshold			0–127		Adjusts the level at which the
#2					noise suppressor will begin to
					take effect.
					* When the signal drops below
					the specified level, it will be
					muted.

Effects List

Parameter	Value	Description
NS Release	0–127	Sets the transition time from
		when the noise suppression
		starts to the point where the vol-
		ume reaches 0.

10: Tape Echo Simulator

This virtual tape echo gives you real tape delay sound. This simulates the tape echo part of Roland’s RE-201 Space Echo.

L

Tape Echo

R

Parameter	Value	Description
Mode	S, M, L, S+M,	Sets the combination of play-
	S+L, M+L,	back heads to be used.
	S+M+L	The RE-201 had three playback
		heads to make different delay
		times (Short, Medium, and Long
		delay) at once. For example, to
		use the short and middle heads,
		select S+M.
Repeat Rate #1	0–127	Sets the tape speed.
		This corresponds to the delay
		time in a contemporary delay ef-
		fect.
Intensity #2	0–127	Sets the repeat times of the de-
		layed sound.
		This is analogous to a contempo-
		rary delay’s feedback setting.
Bass	-100– +100	These are the echo sound’s bass
Treble		and treble adjustments.
		When set to 0, they make no
		change to the sound.
Head S Pan	L63–63R	These are the pan (left-right) set-
		tings for each of the heads for
Head M Pan
		Short, Medium, and Long delay
Head L Pan
		time.
		* This parameter does not
		appear on the original RE-201.
Tape Distortion	0–5	Adds the distortion characteris-
		tic of tape.
		The distortion gets more intense
		as the value is increased.
W/F Rate	0–127	Frequency of the wow and flut-
		ter modulation
		The wavering of multiple pitch-
		es that appears from tape wear
		and irregularities in rotation is	Appendices
		called wow and flutter.
W/F Depth	0–127	Modulation depth of the wow
		and flutter
Echo Level	0–127	Volume of the echo sound.
