SHAPER and PANNER
Our next example incorporates two of the DSP functions, and will give you a general overview
of using the algorithms to build sounds.
Starting with Program 199, press EDIT, and while youÕre on the ALG page, cursor up to the
Algorithm parameter, and select Algorithm 13. Select values of NONE in the F1 and F2 blocks.
The value of the F3 block is already set to PANNER, as shown below.

Next press the KEYMAP soft button to select the KEYMAP page, and select 163 Sine Wave as
the keymap. Play a few notes to accustom you ear to the sound of the unshaped sine wave.
Then return to the ALG page, and select SHAPER for the algorithmÕs F1 block. YouÕll notice a
bit of an effect right away,

Press the more> soft button, then press the F1 AMT soft button. This enables you to adjust the
amount of shaping applied to the sine wave. Try different values for the Adjust parameter, then
set it to its minimumÑ0.100x. Then cursor down to the VelTrk parameter, and set a value of
0.70. Listen for the variation in the effect as you play with different attack velocities.
Now go back to the KEYMAP page, and select different keymaps so you can hear the
SHAPERÕs effect on different sounds. When youÕre Þnished experimenting, set the Keymap
parameter at 152 Dull Sawtooth.
Notice how notes on the high end tend to break up. If you return to the F1 AMT page you can
reduce this distortion and/or
aliasing
with the KStart and KeyTrk parameters.
Select the KStart parameter and set a value of C 2 Unipolar. This limits the amount of shaping
applied to notes above or below C 2, depending on the vale of the KeyTrk parameter. Next set
the value for the KeyTrk parameter to -0.018x / key. Since weÕre using a negative value, the
amount of shaping will decrease with higher notes.
Next weÕll program an envelope to change the SHAPER in realtime. While still on the F1 AMT
page, select the Src2 parameter, and set it to a value of ENV2 (1, 2, 1, ENTER). Cursor down to
the DptCtl parameter and set it to a value of AttVel (1, 0, 0, ENTER). Set the MinDpt parameter
to 0.00x and the MaxDpt parameter to a value of 1.70 x. This will let you use attack velocity to
vary the speed of the envelope.
Next, use the <more> soft buttons to locate the ENV2 soft button, then press it to select the
ENV2 page. Set up the parameters as shown in the diagram on the following page.
