Dynamic Volume Effects

Now that we have a better understanding of how the control
assigns, I-PDL and W-PDL work, let's put the information
together to create some changing volume effects.
Remember I said in section 19 when we discussed the Slicer
that we would liven up the Metal GibSL patch to provide
rate control? Well that's what we are going to do. Turn the
EXP PEDAL off. Now enter these two assigns:
Assign 1

You can now control the Slicer rate. Pedal backwards the
Slicer is off. Rock forwards and it cuts in—getting faster the
further forward you go. As you come back on the pedal the
Slicer rate slows down and finally back at 0 the Slicer is
turned off.
Try this—Strike a Chord, now push forward maybe 75% of
the way forward to achieve a nice fast slice, bring slowly
back until you have a fairly slow slice and then finally finish
off by coming all the way back quickly and shutting off the
Slicer. Now you sound just like a Gibson Les Paul!
On a similar note, we can control the tremolo rate in a
similar manner again but this time the assign targets TR:

Section 23
Use this with the 'Metal Trem' patch. Once again, strike a
chord and come back on the pedal. This produces a nice
slowing effect.
Another thing we can do is create a slicing effect using the
EXP PEDAL. First turn the EXP PEDAL assign off and
enter the three assignments:
Assign 1

This provides us with two areas of on and two of off.
Rocking backwards and forwards on the pedal produces the
slicing, and the rate is simply controlled by how fast you do
it!
One last thing we will examine is the way we can control
two parameters to produce combined effect. We have
already taken a sneak preview at this with the 'Metal Chop'
patch and we shall have another look at it now. The patch
uses two assignments which are:
Assign 1
