LP Freq: 0…127

(In the

delay

filter

tab in the display) Sets the

cutoff frequency of the low-pass filter in the feedback path. A low-pass

setting of 127 results in no filtering. Use the low-pass filter to create

natural-sounding echoes and analog tape echo effects.

HP Freq: 0…127

(In the

delay

filter

tab in the display) Sets the

cutoff frequency of the high-pass filter in the feedback path. A high-pass

filter setting of 127 equals maximum filtering. User the highpass filter to

create interesting flange effects and unnatural sounding echoes.

Pan: -64…+63

(In the

delay

filter

tab in the display) Allows you to

pan the output of a delay anywhere in the stereo field. This is very useful

in creating a rich stereo image as well as for ping-pong echo effects.

Delay Pan is also a modulation destination. That is, the stereo pan position of

the delayed signal can be modulated using an LFO or any mod source in the modula-

tion matrix. Use this to create auto-panning effects.

Buffer Length: Long, Short

(In the

delay

filter

tab of Delay 4 only)

Choose Short, for shorter delays, chorus, or flange type effects. Choose

Long for longer repeat delays and when modulating delay times for

analog delay-style detuning effects.

Creating Reverb and Modulation-Based Effects

As previously noted, you can use the Pro 2’s delays to create not only

simple delays but also flanging and chorus effects, and simple reverbs.

Reverb
A reverb is effectively multiple delays of a source signal as it moves through

a space and bounces off of various surfaces. You can simulate small to

medium sized rooms, spring, and plate reverb effects by using the four delay

paths, feedback paths, and amounts. Try setting each of the delay times to

different time settings between 30 and 70. Set the amounts and feedbacks to

different values and listen to how the sound changes. Altering the values of

the above parameters will “sculpt” the sound of the reverberation.
