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.
tt 0100aaaa aaaa = BDS..."SYSEX_ACT_BDS" = 02H
BDR..."SYSEX_ACT_BDR" = 03H
HDS..."SYSEX_ACT_HDS" = 04H
HDR..."SYSEX_ACT_HDR" = 05H
HDA..."SYSEX_ACT_HDA" = 06H
HDJ..."SYSEX_ACT_HDJ" = 07H
HDE..."SYSEX_ACT_HDE" = 08H
d0[0] 0ooocccc cccc = Parameter Set Category = FX = 03H
ooo = 00H
d0[1] 0ttttttt 0TTTTTTT0ttttttt = Type ID = See the description of each effect
(FX) for details about Type IDs.
d0[2] 0TTTTTTT
d0[3] 0mmmmmmm 0MMMMMMM0mmmmmmm = Mdev ID = Internal RAM = 2F00H
d0[4] 0MMMMMMM
d0[5] 0sssssss 00SSSSSSSsssssss = Section Number
d0[6] 0SSSSSSS
The mixer (MIX) Part/Segment numbers selected by FX go here. This is the same
for IPC and IPR.
d0[7] 0nnnnnnn 00NNNNNNNnnnnnnn = PS Number = 0000H Fixed
d0[8] 0NNNNNNN
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.
