Setting The Feedback; Setting The Filters; Setting The Pan; Setting The Delay Level - Yamaha UD-Stomp User Manual

Using the UD-Stomp

Setting the Feedback

Up to this point we have set the delay time so a
single delay sound is produced 250msec after the
original sound. Next, set the Feedback parameter
to determine how many times the delay will repeat.
4.
Rotate the FEEDBACK knob so that "
pears in the display. The delay sound is re-
peated infinitely without fading out.
When the FEEDBACK is set to a lower value,
the number of times the delay is repeated will
decrease and the delay sound will fade out.
In this step, set the FEEDBACK level to "

Setting the Filters

The delay circuit also includes a HCF (High Cut Fil-
ter) which, cuts high frequencies, and a LCF (Low
Cut Filter) which, cuts low frequencies. Since these
filters are incorporated in the delay loop, the cutting
of the effected frequencies will be greater each time
the delay is repeated.
5.
Rotate the LOW CUT FILTER knob or HIGH
CUT FILTER knob and see how the filters
change the sound.
* For both knobs, a setting of 10 (
frequency of 1kHz and setting of 0 equals off (
* The cutoff is also applied to the first delay.
The use of these filters offers analog simulation, etc.
Once you understand how the filters operate, set

Setting the Pan

The term "Pan" refers to the position of the delayed
sound within the stereo field of the left and right
speakers. Use the PAN knob to set the position of
the delayed sound somewhere between left (
C
center ( ) and right (
tion below.
6.
Rotate the PAN knob and see how the delay
sound moves between the left and right speak-
ers.
Once you understand how the PAN knob oper-
ates, set the PAN knob to "

of the delay sound.

Use the [UP] button and recall patch "
This patch will make it easy to understand how
this effect works.
In this patch a 360msec delay is already set to
both Effect Bands 1 and 2. Notice that the de-
lay sound is louder than the original. That's be-
cause both delay sounds, which are heard si-
multaneously, are set at the same level as the
original sound.

Press the [EFFECT BAND 1] button and rotate
the TAP knob to change Tap Value of Effect
Band 1.

the sound of the two delays creates a shuffle

Effect Band 1 is being produced at 240msec,
which is 2/3 (66.6%) of its 360msec delay time.
