Offset Vs. Scale - Kurzweil PC2R Musician's Manual

8. Press the Right cursor button. The display shows a prompt asking if you want to paste to
Zone 1.
9. Press Zone 3, then Enter. The display shows
prompt.
10. Take a minute to save the setup as 133 Offset. You'll see why we chose that name in a
minute. Once you've saved, you're no longer in the Setup Editor.
11. Now we'll change the program assignment for Zone 3. Press Edit to enter the Setup
Editor, then press the Right cursor button until you see the Program menu. Press Enter.
12. Use the Alpha Wheel to select Program 016 Classic E Piano.
13. Now we'll change the wet/dry mix of the acoustic piano. Press Zone 1 to make Zone 1
active.
14. Hold the Global button, and turn Knob A. Press the Right cursor button until you see the
Ctrl Offset parameter. Turn the Alpha Wheel to the left until the value is –64.
This sets an offset of -64 for Green Knob A in Zone 1. The offset uniformly subtracts 64
from the value of the slider (a positive offset would uniformly add to the value). When the
knob is all the way up, the value is (127 – 64) or 63. therefore, the acoustic piano will
always have a wet/dry mix that's 64 lower than the electric piano.
15. Save again, replacing Setup 133 without renaming.
Now try playing some notes and adjusting Knob A (make sure the Shift LED is still
green). As you move the knob left 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 – 64). In the
bottom half of the knob's throw, you'll hear chorus only on the electric piano.

Offset vs. Scale

There's another way to adjust levels relative to each other that gives slightly different results.
1. Select Setup 133 if necessary, and make Zone 1 current, if it isn't already.
2. Hold the Global button, and turn Knob A.
3. Press the Right cursor button until you see the Exit Value parameter for Green Knob A.
4. Press the Left cursor button once, to select the Ctrl Scale parameter. Set its value to 50%.
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 turn Knob A to the left, the
difference in the wet/dry mix values between the two sounds gets smaller, until they meet at 0.
