Plus/Minus buttons). This will prevent the vibrato from fading as it did. (This fading was
caused by the ASR repeating, which was the default setting). Now select the Delay parameter
and set its value to .4 seconds (4, 0, ENTER). Select the Attack parameter and change its value to
.48 seconds (4, 8, ENTER). The vibrato should now begin to fade in gradually after a short
delay, then remain constant at a rate of 4.40 cycles per second. The ASR page should look like
the page below. We're finished with the delayed vibrato; next is the velocity stab.

We want the stab to drop the trumpet's pitch and amplitude, but only when notes are played
fortissimo or louder. This is done by using ASR1 as a control source on both the PITCH and
AMP pages, then using a velocity trigger (VTRIG) to control ASR1.
First return to the PITCH page (if you're still on the ASR page, press the more> soft button
three times, and the PITCH soft button will appear). Press PITCH, then select the Src1
parameter, and set its value to ASR1 (press 1, 1, 0, ENTER or hold ENTER and strike B5). Then
select the Depth parameter, and set its value to –1200 cents (+/-, 1, 2, 0, 0, ENTER). ASR1 has
non-zero default values in Program 199, so you'll hear the pitch drop an octave if you strike
and hold a note. The PITCH page should look like this:

The next step is to adjust the characteristics of the stab by programming ASR1. Select the Src1
parameter again, and press EDIT to select the ASR page.
First, select the Trig parameter, and assign a value of VTRIG1 (press 1, 0, 6, ENTER or hold
ENTER and strike E5). Select the Delay parameter and set its value to .34 seconds (3, 4, ENTER).
Set the Attack parameter to a value of .78 seconds. The ASR page should now look like this:

Notice that the soft buttons are identical to those on the PITCH page; this is because you
pressed EDIT to call up the ASR page, instead of using the more soft buttons.
