[. . . ] 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 selects Effect Band 1) then press the [CONNECT] button at which time "in" appears in the display. This indicates that the signal received by the delay circuit of Effect Band 1 is coming directly from the UD-Stomp's INPUT jack. Effect Band 2 is also set to "in". 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. 15 Using the UD-Stomp Now Effect Bands 1 and 2 are connected as shown in the illustration below. IN IN 1 4 BAND 1 BAND 8 BAND 3 BAND 4 BAND 5 BAND 6 BAND 7 BAND 2 BAND 1 BAND 2 IN 8 5 IN IN 3 You can hear a single short delay and a single long delay being produced. 2 4 BAND 5 BAND 6 BAND 7 BAND 8 BAND 2 2 19. Next, try and connect Effect Bands 1 and 2 in a series. Press the [EFFECT BAND 2] button, then hold the [CONNECT] button and press the [UP] button so that "1" is shown in the display. The output signal of Effect Band 1 (the original sound mixed with the delay sound) is now sent to the input of Effect Band 2. Effect Band 1 and Effect Band 2 are now connected in a series. IN IN BAND 4 3 4 BAND 3 3 IN BAND 1 Grouping Multiple Effect Bands (GROUP) The Group function makes possible longer delay times by combining multiple Effect Bands into a single delay circuit. BAND 1 1 BAND 2 Now you can hear a short delay applied to both the original sound and the long delay sound. 20. Now let's try and make a complex delay using these two Effect Band circuits. Set the Delay Time of Effect Band 2 to 419msec and increase the FEEDBACK of both Effect Bands equally. With the two Effect Bands connected in a series, the delay effect becomes more and more complex as the delay is repeated. Try changing Delay Time for each Effect Band to create some other effects. * Parallel and series connections can be mixed together. You can also synchronize the modulation between Effect Bands ( page 17) to create a more complex delay effect. 21. Let's try and make a long delay time. Recall patch "9. 11" and press the [EFFECT BAND 1] button, then use the TIME COARSE knob and TIME FINE knob to set the delay time to its maximum of "696. "msec. 22. Hold the [GROUP] button and use the [UP] button to set the parameter to "1-2". Now Effect Bands 1 and 2 are combined into a single delay circuit that is referred to as a Group. Notice now that the delay time is longer. Rotate the TIME COARSE knob a little and notice that the Delay Time shown in the display is "143" (1430msec). [. . . ] Is the volume level of the instrument connected to the INPUT jack turned up? Are the EFFECT LEVEL knob and the DIRECT LEVEL knob values set to "0"? Is the OUTPUT LEVEL knob value set to "0"?Pedal is being used to control the volume, try stepping on the pedal. [. . . ]
