4.8 MASTER REVERB SECTION
Master reverb parameters.
A reverb is the sum of different acoustic reflections,
created by sound in a natural environment. For example,
when clapping hands inside a large space, such as a
church, the sound will resonate and slowly decay. Large
rooms and halls create reverb. The acoustic effect
depends on many different factors, such as the room's
size and shape, the material covering the walls and so
on.
MASTER REVERB ON/OFF
Range: Off, On
NRPN MSB=7 NRPN LSB=0
Data Entry MSB Range: 0, 1
Enables/disables the MASTER REVERB section.
TYPE
Range:
-
Small Room: a small room with very absorbing
walls.
-
Large Room: a medium room with slightly
absorbing walls.
-
Small Hall: a small hall with reflective walls, such
as a small church.
-
Medium Hall: a medium hall with very reflective
walls.
-
Large Hall: a large hall with very reflective walls,
such as a cathedral.
-
Plate: reverb simulation generated by a metal
plate, a technique used in the '70s.
-
Spring: reverb simulation generated by a
spring, a technique used in the '70s with
amplifiers.
-
Tape: reverb simulation generated by an analog
tape, by recording and replaying the final
portion of the reverberated sound.
NRPN MSB=7 NRPN LSB=1
Data Entry MSB Range: 0...7
Select the type of room generating the reverb,
TIME
Range: 0...127
NRPN MSB=7 NRPN LSB=2
Data Entry MSB Range: 0...127
Sets the time of reverbetations.
HI DAMP
Range: 0...127
NRPN MSB=7 NRPN LSB=3
Data Entry MSB Range: 0...127
Sets the cutoff frequency of a low-pass filter, that
dampens the reverberated signal with a higher
frequency, softening the effect.
LOW GAIN
Range: -0,6...0...0,6 dB
NRPN MSB=7 NRPN LSB=4
Data Entry MSB Range: 0...127
Sets the gain (positive values) or attenuation
(negative values) of low frequencies.
HIGH GAIN
Range: -0,6...0...0,6 dB
NRPN MSB=7 NRPN LSB=5
Data Entry MSB Range: 0...127
Sets the gain (positive values) or attenuation
(negative values) of high frequencies.

LEVEL
Range: 0...127
NRPN MSB=7 NRPN LSB=6
Data Entry MSB Range: 0...127
Sets the output signal level.
4.9 MASTER EQUALIZER SECTION
Master equalizer parameters.
MASTER EQUALIZER ON/OFF
Range: Off, On
NRPN MSB=8 NRPN LSB=0
Data Entry MSB Range: 0, 1
Enables/disables the MASTER EQUALIZER section.
MASTER EQUALIZER TYPE
Range: Parametric, Graphic
NRPN MSB=8 NRPN LSB=1
Data Entry MSB Range: 0, 1
Sets the equalizer type (graphic or parameter).
GRAPHIC
A graphic equalizer controls certain preset frequency
bands. Each band can be boosted or attenuated.

LOW
Range: -12...0...+12 dB
NRPN MSB=8 NRPN LSB=2
Data Entry MSB Range: 52...64...76
Gain (positive values) or attenuation (negative
values) of signals with frequencies around 180 Hz.
LOW-MID
Range: -12...0...+12 dB
NRPN MSB=8 NRPN LSB=3
Data Entry MSB Range: 52...64...76
Gain (positive values) or attenuation (negative
values) of signals with frequencies around 350 Hz.
MID
Range: -12...0...+12 dB
NRPN MSB=8 NRPN LSB=4
Data Entry MSB Range: 52...64...76

HI-MID
Range: -12...0...+12 dB
NRPN MSB=8 NRPN LSB=5
Data Entry MSB Range: 52...64...76
Gain (positive values) or attenuation (negative
values) of signals with frequencies around 1,8 KHz.
