Density (DENSITY):
EARLYREF.2: 1 – 3
EARLY REF.
3,
GATE REVERB, REVERSE GATE:
Please note that the DENSITY parameter is not provided in
the EARLY REF. 1 program. This parameter determines the
density of the reverb reflections (i.e. the average amount of
time between reflections). A setting of 0 or 1 produces
minimum reverb density for a more spacious sound, while a
setting of 3 produces the most dense, “tightest” reverberation.
DELAY PROGRAM
11. DELAY L,C,R
This sophisticated delay effect offers independently variable
left, right and center channel delays.
PARAMETERS ACCESSED BY THE PARAM KEY
Left Channel Delay (Lch DLY): 0.1 – 5200
milliseconds
Right Channel Delay (Rch DLY): 0.1 – 5200
milliseconds
Center Channel Delay (Cch DLY): 0.1 – 5200
milliseconds
These parameters individually set the time between the direct
sound of the instrument and the first repeat heard from the
left, right and center channels.
Center Channel Level (Cch LVL): -200 – +200%
Adjusts the level of the center-channel delay signal.
PARAMETERS ACCESSED BY THE INT PARAM
KEY
High-pass Filter Frequency (HPF FRQ): THRU, 32 Hz
– 1 k H z
Permits rolling off the low-frequency content of the reverb
signal above the set frequency. The HPF is OFF when set to
THRU.
Low-pass Filter Frequency (LPF FRQ): 1 – 16 kHz,
THRU
Permits rolling off the high-frequency content of the reverb
signal above the set frequency. The LPF is OFF when set to
THRU.
Feedback 1 Delay (FB1 DLY): 0.1 – 5200 milliseconds
Feedback 2 Delay (FB2 DLY): 0.1 – 5200 milliseconds
Two separate feedback loops are provided in the delay
program, and these parameters determine the amount of delay
applied to each feedback signal.
Feedback 1 Gain (FB1 GAIN): -99% – +99%
Feedback 2 Gain (FB2 GAIN): -99% – +99%
Set the amount of delay signal fed back to the input of the
processor. The higher the feedback gain setting, the greater
the number of delayed repeats produced by the corresponding
feedback loop.
High Frequency Feedback (HIGH): x0.1 – x1.0
Controls feedback in the high-frequency range. The high-
frequency feedback is reduced as the value of this parameter
is decreased.
ECHO PROGRAM
12. STEREO ECHO
The stereo echo effect offers independently variable left and
right channel initial delays and echo intervals.
PARAMETERS ACCESSED BY THE PARAM KEY
Left Channel Feedback Delay (LFB DLY): 0.1 – 2600
milliseconds
Right Channel Feedback Delay (RFB DLY): 0.1 – 26000
milliseconds
