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 4-18. Use a sustaining sound
2. Make Zone 1 current, then enter the Controllers menu in the Setup Editor. Go to the Ctrl
3. Press the Right cursor button to select the Ctrl Offset parameter, and to 127.
That's all it takes to create a crossfade. You'll 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 the Right cursor button to select the Ctrl Curve
2. Make Zone 2 current, 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 midrange—but
since we've inverted the curve with scaling and offset, it also boosts the volume in the midrange.

Velocity Switching

You can use your keystrike velocity (how hard you play) to change sounds. This is how program
000 Stereo Grand works: there are actually three sets of samples, one for soft, one for medium,
and one for loud.
1. Create a two-zone setup. Go to the Program menu in the Setup Editor. Assign program
2. Press Menu to exit the Program menu, then press the Right cursor button until you see
3. Press the Right cursor button four times to select the Max parameter. Note that this is one
4. Set the value of the Max parameter to 80. Note that the Min value for Zone 1 is 1. This is
5. Make Zone 2 current. Press the Left cursor button to select the Min parameter. Set its
