Operation

This is a multiple effector stereo version of Lo-Fi that produces artificial Lo-Fi sounds. The phonograh record noise generation function of the monaural Lo-Fi effector is not available in stereo.

Stereo Lo-Fi includes the following functions, which can be enabled simultaneously.

*Reduction of input signal fidelity

*Simulation of power supply hum noise simulation

*Generation of white noise and pink noise generation

*Equalizer

1.Bypass

Effector function enable/disable. Selecting bypass causes the input signal to be output as-is.

2.LoFiType

Level of fidelity reduction in input signal. A greater value causes a greater reduction in fidel- ity and deterioration of the tone.

3.LoFiMix

Mix level of signal whose fidelity is reduced

4.HumFreq

Hum noise frequency

5.HumLevel Hum noise level

6.NoiseMode

Noise mode: white noise or pink noise

7.NoiseLevel

White noise or pink noise level

8.Lo Freq

Low range filter frequency

9.Lo Gain

Low range level

10.Hi Freq

High range filter frequency

11.Hi Gain

High range level

12.Dir Level

Input direct signal output level

4.8.7 FX Parameter Set Bulk Dump

The FX Parameter Set can be sent and received using bulk dump. There are two protocols, One- Way and Handshake, which are the same as those described under "4.1 MZ-2000 Sound Source Common System Exclusive Format."

The following shows the section that applies to effects only.

The content and size of the data depend on the FX. Since the volume of data is very large, and it is not included here. This data can be looked up by sending HDR and BDR.
