Editing VAST Programs With KVA Oscillators
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.
1 Block:
LPNOIZ
A noise generator combined with a low pass filter. Use the Noiz Frq parameter to control the
cut off frequency of the filter.
NOISE
A simple noise generator. Use the Noise parameter to control the noise initial amplitude.
SW + SHP (Sawtooth + Shaper)
This oscillator is capable of basic FM Synthesis. Its distinctive parameter is Pch Coar. This
oscillator must come after the sound source in an algorithm (either keymap or oscillator)
in order to hear the effect of Pch Coar, which can radically change whatever the oscillator
receives as an input. Works well placed after a Sine source.
SINE+ [Aliased (not recommended)]
Same as 2 block version, but without the Sine+Am parameter.
SAW+ [Aliased (not recommended)]
A saw oscillator that can add an input signal to its output.
NOISE+ [Aliased (not recommended)]
A noise oscillator that can add an input signal to its output.
2 Block:
SINE+
A sine oscillator that can add an input signal to its output. The Sin+ Pch and Sine+ Am
parameters affect the pitch and amplitude of the sine waveform without affecting the pitch of
the input source.
