Edit/Effect Parameters 23
GAIN Range: -48 to +24 dB
This parameter sets the amount of boost or cut applied to the high shelving filter.
EQ TRIM Range: -24 to +00 dB
This parameter allows you to adjust the input volume of the EQs to eliminate the possibility of
clipping boosted signals.
MOD SRC 1 MOD SRC 2
DST 1 DST 2
MIN 1 MIN 2
MAX 1 MAX 2
These parameters are explained in detail in Section 5 — Effect Concepts.
ROM-34 EQ+VIBR+DDL
EQ+VIBR+DDL combines a vibrato effect (a pitch shifter modulating over a very small range)
with EQ and digital delay. Many vintage guitar amplifiers offered a vibrato control, but don’t
feel that this effect is limited to guitars, try this with other sources as well. There is a sample &
hold parameter that doesn’t hold the instantaneous pitch shift, but if set properly will provide a
“chirping” effect when acting on the input signal.

In this effect the signal enters a programmable EQ, which is preceded by an input level trim. The
signal is then routed to the vibrato. The vibrato is routed directly to the output. The vibrato also
passes through the delay which is then regenerated back into the delay. A different delay signal
is routed to the output on the right side. This constitutes a “ping-pong” delay effect. The Delay
Feedback parameter between the delay sends controls the delay feedback amount. There are also
two echoes that are sent to the left and right outputs respectively. The signal from the two echoes
has one level control. There is also an external dry signal (not shown) that goes directly from the
input to the output (BUS3). The BUS1 and BUS2 MIX parameters can be routed into the effect
with different Dry/Wet mixes.
The parameters available for this algorithm are:
VIBR RATE Range: 0 to 99
This parameter sets the amount of modulation. Higher values create a faster vibrating rate.
WIDTH Range: 0 to 99
This parameter sets the width (adjusts the amount) of the modulation.
