11:STEREO PHASER

This is a stereo phaser.

Parameter	Value	Description
Mode	4, 8 stage	Number of stages in the phaser
Polarity	INVERSE,	Selects whether the left and right
	SYNCHRO	phase of the modulation are the
		same or opposite each other.
		INVERSE: The left and right
		phase are opposite. When using a
		mono source, this spreads the
		sound in stereo.
		SYNCHRO: The left and right
		phase are the same. Select this
		when working with a stereo source.
Rate #2	0.05–10.00	Frequency of modulation
	Hz, note
Depth	0–127	Depth of modulation
Manual #1	0–127	Adjusts the basic frequency from
		which the sound is modulated.
Resonance	0–127	Amount of feedback
Cross	-98– +98 %	Adjusts the amount of the phaser
Feedback		sound that’s fed back into the effect.
		Negative (-) settings invert the phase.
Mix	0–127	Level of the phase-shifted sound
Low Gain	-15– +15 dB	Gain of the low frequency range
High Gain	-15– +15 dB	Gain of the high frequency range
Level	0–127	Output level

12:STEP PHASER

With the Step effects, you can also make stepped changes in the pitch of sounds to which the Phaser effect is applied.

13: RING MODULATOR

This is an effect that applies amplitude modulation (AM) to the input signal, producing bell-like sounds. You can also change the modulation frequency in response to changes in the volume of the sound sent into the effect.

	Ring Mod		2-Band EQ
Parameter		Value		Description		Effects
Frequency		0–127		Adjusts the frequency at which
#1				modulation is applied.
Sens		0–127		Adjusts the amount of frequency
				modulation applied.
Polarity		UP,		Determines whether the frequency
		DOWN		modulation moves towards higher
				frequencies (UP) or lower frequen-
				cies (DOWN).
Low Gain		-15– +15 dB		Gain of the low frequency range
High Gain		-15– +15 dB		Gain of the high frequency range
Balance #2		D100:0W–		Volume balance between the direct
		D0:100W		sound (D) and the effect sound (W)
Level		0–127		Output level

14: TREMOLO

Cyclically modulates the volume to add tremolo to the sound.
