it is cut off frequency for the low pass filter. For this example, leave this initial value set to
its default. With the LP Frq parameter selected, press right on the cursor button to get to
this function's sub page (the right half of the display). Select the Veltrk parameter and use
the alpha wheel or alpha numeric pad to turn it all the way up to 10800ct. Now keyboard
velocities will affect the LP Frq parameter. A velocity of 127 will cause the filter's cut off
frequency to move up 10800 cents from its initial value, a velocity of 0 will have no effect on
the cut off frequency, and values in between will increase the cut off frequency by a scaling
between 0 and 10800 cents. Overall, this will cause higher played velocities to increase the
cut off frequency, making the oscillator sound brighter, and lower velocities to lower the cut
off frequency, making the oscillator sound duller. This method can be used to control any
DSP function that is loaded into an algorithm. See
page 7-33, for other control parameters available on the DSPCTL page.
Alternatively, you could assign cut off frequency to be controlled by any continuous
controller, such as the Mod Wheel. Start again with the unedited Program 1023 Editor
Template. Follow the same steps as above, but instead of changing any parameters on the
DSPCTL page, press the DSPMOD soft button to reach the DSP Modulation page. On
the left side of the screen, choose the parameter for LP Frq, and then press the right cursor
button to reach the LP Frq sub page. On this sub page, you can assign any continuous
controller to control the cut off frequency of the LOPASS function (or the main parameter
for any function loaded in the current algorithm). Select the Src1 parameter, hold the Enter
button and move the Mod Wheel to quickly select MWheel (the Mod Wheel) as your
control source. Next, press the cursor down button to select the Depth parameter, then use
the alpha wheel or alpha numeric pad to turn it all the way up to 10800ct. Now the Mod
Wheel will affect the LP Frq parameter. Moving the Mod Wheel all the way up (a value of
127) will cause the filter's cut off frequency to move up 10800 cents from its initial value,
moving the Mod Wheel all the way down (a value of 0) will have no effect on the cut off
frequency, and values in between will increase the cut off frequency by a scaling between 0
and 10800 cents. Now you have the same control over cut off frequency as you did in the
previous example, but now it is controlled by the Mod Wheel. Overall, moving the Mod
Wheel up will increase the cut off frequency, making the oscillator sound brighter, and
moving the Mod Wheel down will lower the cut off frequency, making the oscillator sound
duller. This is useful to control a classic "filter sweep" sound. The above method can be
used to control any DSP function that is loaded into an algorithm, and you can choose any
continuous controller as a control source.
Oscillator Specific Control And Modulation Parameters:
Several KVA oscillators also have their own modulation parameters that must be accessed
to control the oscillator's intended function. Below is a list of these oscillators and their
distinctive parameters, grouped by block size. Though the following parameters could be left
at one setting, utilizing one of the DSPCTL or DSPMOD techniques described in the above
examples will expose a wider range of expression from each oscillator.
