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 DSP CTL or DSP MOD 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 combines a dull sawtooth waveform with an input signal, and passes the input
signal through a shaper effect, which can produce timbres similar to FM synthesis. When
this oscillator is placed after the sound source in an algorithm (either a keymap or another
oscillator), changing the Pch Coar parameter can radically change the sound of the input
signal. It can be useful to place a 1 block gain function before this oscillator, in order to
control the depth of the shaper effect.
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.
