combines a tremolo effect, which is a pulsating change in volume, with
an EQ and a digital delay.
EQ-Tremolo-DDL Signal Routing
Main
Outputs
The signal enters an input level trim (parameter 17) followed by a programmable EQ and is then
routed to the tremolo. The tremolo is routed directly to the output. The left channel signal passes
through the digital delay and is routed back into the delay. There is another signal from the
delay that is routed to the output on the right side. One Regen parameter (09) between the delay
sends controls the left and right delay level. This constitutes the "ping-pong" effect. There are
two echoes that are sent to the left and right outputs respectively. The signal from the two
discrete echoes has one level control. There is also an external dry signal (not shown) that goes
directly from the input to the output and is controlled with the mix parameter (01).
The parameters available for this algorithm are:
01- Mix
02-Volume
See the descriptions under the Mix and Volume Parameters, in the beginning of this section.
03 - Tremolo Rate
Range: 000 to 200
This parameter sets the rate of modulation. Mid values create a faster wavering sound. High
values will raise the level up into the audio range, creating a ring modulation (amplitude
modulation) effect. This parameter, when used in conjunction with the Sample
&
Hold Rate
parameter, can create some interesting staccato effects.
04 - Tremolo Depth
Range: 00 to 99
This parameter sets the depth of amplitude modulation.
05 - LeWRight LFO
Range: Out-of-Phase or In-Phase
Controls whether the left and right channels of the stereo tremolo will modulate in or out-of-phase.
