L in	Compressor		Lo-Fi	L out
R in				R out
	Compressor		Lo-Fi
Parameter		Value	Description
Pre Filter		1–6	Selects the type of filter applied to
Type			the sound before it passes through
			the Lo-Fi effect.
LoFi Type		1–9	Degrades the sound quality. The
			sound quality grows poorer as this
			value is increased.
Post Filter		OFF, LPF,	Type of filter
Type		HPF	OFF: no filter is used
			LPF: cuts the frequency range
			above the Cutoff
			HPF: cuts the frequency range
			below the Cutoff
Post Filter		200–	Basic frequency of the Post Filter
Cutoff		8000 Hz
Balance #1		D100:0W–	Volume balance between the direct
		D0:100W	sound (D) and the effect sound (W)
Level #2		0–127	Output level

32: LOFI RADIO (Lo-Fi Radio)

In addition to a Lo-Fi effect, this effect also generates various types

of noise, such as radio noise or disk noise.

Radio		0–127		Simulates the tuning noise of a ra-
Detune #1				dio. As this value is raised, the tun-
				ing drifts further.
Radio Noise		0–127		Volume of the radio noise

34: PHONOGRAPH

Simulates a sound recorded on an analog record and played back on a record player. This effect also simulates the various types of noise that are typical of a record, and even the rotational irregularities of an old turntable.
