Oscillator Specic 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. ough 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 lter. Use the Noiz Frq parameter to control the
cut o frequency of the lter.
NOISE
A simple noise generator. Use the Noise parameter to control the noise initial amplitude.
SW + SHP (Sawtooth + Shaper)
is oscillator combines a dull sawtooth waveform with an input signal, and passes the input
signal through a shaper eect, 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 eect.
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. e Sin+ Pch and Sine+ Am
parameters aect the pitch and amplitude of the sine waveform without aecting the pitch of
the input source.
