Programs 17 through 20 combine delay or echo and distortion.
Distortion Levei (DiSTORTiON): 0 — 100%
Sets the "degree” or “depth” of the distortion portion of the
effect.
Deiay Baiance or Echo Baiance (DELAY BAL or
ECHO BAL): 0 — 100%
Determines the amount of delay or echo effect applied to the
distortion sound.
Left Channel Delay (Lch DL Y):
0.1 — 500 mitiiseconds in programs 17 & 20
0.1 — 250 miiiiseconds in 18 & 19
Sets the time between the direct sound of the instrument and
the first repeat heard from the left channel.
Midrange EQ Gain (MiD GAiN): -12 —+12 dB
Boosts or cuts response in the frequency range set by the
MID FRQ parameter (above). A setting of 0 produces no
boost or cut. Minus settings (e.g: -6 dB) cut response in the
selected frequency range, while plus settings (e.g: +12 dB)
boost response.
Trigger Levei (TRG. LEVEL): 1 — 100
Determines the amplitude of the input signal required to
trigger the effect. This parameter functions effectively as a
noise gate to cut out hiss and noise when an input signal is
not present. TRG LEVEL should be set so that the effect is
activated only when a note is played on the instrument
used.
Left Channel Feedback Gain (Lch F.B): -99% — +99%
Sets the amount of the left-channel delay signal fed back to
the input of the processor. The higher the feedback gain
setting, the greater the number of delayed repeats pro
duced.
Right Channei Deiay (Rch DLY):
0.1 — 500 miiiiseconds in programs 17 & 20
0.1 — 250 miiiiseconds in 18 & 19
Sets the time between the direct sound of the instrument and
the first repeat heard from the right channel.
Right Channei Feedback Gain (Rch F.B): -99% —
+99%
Sets the amount of the right-channel delay signal fed back
to the input of the processor. The higher, the feedback gain
setting, the greater the number of delayed repeats produced.
High Frequency Feedback (HiGH): xO. 1
—
xl.O
Controls feedback in the high-frequency range. The high-
frequency feedback is reduced as the value of this parame
ter is decreased.
Midrange EQ Frequency (MiD FRQ): 500 — 4000 Hz
Sets the mid-frequency range to be boosted or cut using the
next parameter: MID GAIN.
