In this step, set the FEEDBACK of Effect Band
1 to “
5.0
”. Now the first delay is produced after
240msec but the delays that follow that are pro-
duced at 360msec.

Next, set the FEEDBACK of Effect Band 2 to
“
5.0
” as well. First press the [EFFECT BAND
2] button to select Effect Band 2, then use the
FEEDBACK knob. Now, the shuffle rhythm is
repeated.
12.
Now, try setting the PAN of Effect Band 1 all the
way to the left (
L10.
) and the PAN of Effect
Band 2 all the way to the right (
r10.
). Now
you’ve created a stereo ping-pong delay effect.
Setting the Modulation
Adding Modulation to the Delay Time causes the
delay sound’s pitch to change. This can be used to
create effects such as chorus, flanger, etc.

Recall patch “
9.11
” again.
14.
Press the [EFFECT BAND 1] button and use
the TIME COARSE knob to set the delay time
to “
600.
”
15.
Set the SPEED knob to “
4.0
” and the DEPTH
knob to “
10.0
” and listen to the resulting sound.
The pitch of the delayed sound goes up and
down. This is a Modulation effect.
16.
To get a Chorus effect, set the delay time some-
where between 5 and 20msec, then adjust the
SPEED (to make the pitch fluctuating) and
DEPTH (to increase the intensity of the effect).
Also, you create a richer sound by using mul-
tiple Effect Bands or by changing the PAN posi-
tion from right to left. Try varying these param-
eters and see what you get.
17.
To get a Flanger effect, set the Delay Time
shorter than that for the Chorus effect (less than
5msec) then use the SPEED and DEPTH knobs
to produce the Flanger effect. To get a deeper
Flanger effect, increase the FEEDBACK level.
Connecting Multiple Effect Bands
(CONNECT)
Try connecting the 8 Effect Bands together. You can
create a wide variety of delays by connecting mul-
tiple Effect Bands into series or parallel arrange-
ments.
18.
Recall patch “
9.13
”. This patch uses two delay
circuits (Effect Bands 1 and 2) with a parallel
connection.
Effect Band 1 has a long delay of 600msec while
Effect Band 2 has a short delay time of 80msec.
FEEDBACK on both Effect Bands is set to 0.
Press the [EFFECT BAND 1] button (this se-
lects Effect Band 1) then press the [CONNECT]
button at which time “
in
” appears in the dis-
play. This indicates that the signal received by
the delay circuit of Effect Band 1 is coming di-
rectly from the UD-Stomp’s INPUT jack. Effect
Band 2 is also set to “
in
”.
