Vital VST Masterclass, Module 2 - Oscillator Processing




We discussed the basic sound generation principle, wavetable editing, and creation in Vital in the last module.

In this Module, I am gonna talk about various processing units in the Oscillator of Vital.


The Oscillator Pitch Controls


In Vital Oscillator, we have 2 oscillator controls.


  1. In Semitones - The Pitch is set in semitone from -48 to +48. 1 Octave = 12 Semitone

  2. In Cents - The Pitch is set in cents from -100 to +100 ; 1 Semitone = 100 Cents


Transpose Snap


The Transpose snap as the name suggests snaps the keyboard notes to a particular value. All other notes will trigger the frequency of the nearest Selected Transpose note.



Oscillator Level

The oscillator level sets the amplitude of waveforms in the wavetable. This does not set the value in dB, but rather on a scale of 0 to 1. But the effect of the parameter is the same as dB.


Pan

Sets the panning of the oscillator.


Oscillator Routing


This option sends the output of oscillators to various processing units. There are various configurations.


  1. Filter 1 - Sends the Oscillator Output to Filter 1.

  2. Filter 2 - Sends the Oscillator Output to Filter 2.

  3. Filter 1+2 - Sends the Oscillator Output to both filters

  4. Effects - Bypass the filters and sends the oscillator output to Effect Section.

  5. Direct Out - Bypass the filters as well as effects and send the oscillator output to the master.


Unison in Vital vst Plugin


What is Unison in Music?


Unison/Prime creates the copy of the original audio signal coming out of the main oscillator window. You can alter the phase, pitch, stereo width and process the entire signal(original and clones). This processing emulates the positions, pitch, and environment. Think of Unison value 9 as 9 oscillators playing the same note at the same pitch but with different instruments from different locations.


It's like copying your friend's assignments, you copy as it is, then does a little makeover to make it stand out.


Unison gives a great character as well as weight to the sound.


Vital VST Unison


Vital can create up to 16 Unison Voices per octave. The unison has two controls associated with it.


Unison Detune - Unison detune makes the individual unison voices out of tune-up to a small value and changes the position of the voices in the stereo field at the same time. this change creates a continuous interference of phase among unison voices and creates a dynamic phase change. Unison Detune


Unison Detune Power - This option controls the distance among the unison voices.



Phase in Vital Oscillator


There are two-phase options in Vital


  1. Starting Phase


This phase decides the starting position of the waveform, 0 means the waveform will start from the beginning, 180 starts the waveform from the middle, and 360 means the single wave cycle will start from the end.


2. Running Phase Randomization


This option triggers a different phase value every time you play a note. This allows waveforms from different oscillators to interact with each other in different ways and create different outputs.

This function can be very useful in creating a unique character in your sound(For example in pluck).

To experience this change you must have at least 2 waveforms playing(inside or outside the plugin).
