Programming Your PC2
The Setup Editor
18. Save again, replacing Setup
133
without renaming.
As you move the slider down to the midpoint, the Controller value of the wet/dry mix for
the electric piano is 64, and the value for the acoustic piano is 0 (64 Ð 64). In the bottom
half of the sliderÕs throw, youÕll hear chorus only on the electric piano.
Offset vs. Scale
ThereÕs another way to adjust levels relative to each other that gives slightly different results.
1. Select Setup
133
if necessary, and press
Controllers
. Make Zone 1 current, if it isnÕt
already.
2. Set the offset for Slider
A
in Zone 1 back to
0
.
3. Press
<
once, then press
5
,
0
,
Enter
. This sets a scale of
50%
for the wet/dry mix.
Whereas an offset provides a uniform difference between the wet/dry mix for the acoustic and
electric pianos, scaling creates a proportional difference. As you move Slider
A
down from the
top, the difference in the wet/dry mix values between the two sounds gets smaller, until they
meet at 0.
Crossfades
You can use a single continuous controller to fade one sound out while it fades another sound in.
This is called a crossfade.
1. Create a two-zone setup, as you did in the example on page 4-13. Use a sustaining sound
in each zone: perhaps two different organs. (If you want, you can use Setup
129
, and
change the piano to an organ.)
2. Press and hold
Controllers
, and move Slider
A
. Make Zone 1 current, if it isnÕt already
(press
Zone 1
).
3. Make Zone 2 current (press
Zone 2
).
4. Press
>
, then change the value of the Ctrl Scale parameter to
-100%
.
5. Press
>
, then change the value of the Ctrl Offset parameter to
127
.
ThatÕs all it takes to create a crossfade. YouÕll notice a bit of a drop in volume at the midpoint
between the sounds. You can adjust that.
1. Starting from the previous example, press
>
, then change the value of Ctrl Curve to
Cos+
.
2. Make Zone 1 active, and change its Ctrl Curve parameter to
Sin+
. Notice the difference?
Explaining why this works can get a bit technical. The easy explanation is that the Sin+ curve
boosts the volume in the midrange, while the Cos+ curve
cuts
the volume in the midrangeÑbut
since weÕve inverted the curve with scaling and offset, it also boosts the volume in the midrange.
