EFFECT PARAMETER
The Virus vocoder has two banks of up to 32 bandpass lters: One to analyse the frequency spectrum of a
modulator audio signal, and the other to process a carrier signal (usually the internal oscillators) accordingly.
Mode
Carrier ignal Meaning
Off The Vocoder is disabled, no other Vocoder parameters will be visible.
Oscillator The carrier is the entire oscillator section, including any noise.
Osc Hold Identical to “Osc” except that Hold mode is activated for the vocoder.
Noise The carrier is the noise signal only. The rest of the oscillator section is disabled
In L, In L+R, In R The carrier is one or both of the audio inputs.
Spread
-64 to +63: Simultaneously controls Carrier Spread and Modulator Spread (see below).
Q-Factor
-64 to +63: Simultaneously controls Carrier Q and Mod Q (see below), overriding those two parameters.
Only available if both lter SELECT buttons are active.
Carrier Spread
-64 to +63: How far apart individual Carrier bands are. The standard value is +63 (100% i.e. full range),
negative values effectively invert the order of bands - great for special effects.
Modulation destination “Filter1 Key Follow“.
Carrier Q
0 to 127: Quality (steepness) of the Carrier bands.
Modulation destination “Filter1 Resonance“.
Modulator Spread
-64 to +63: How far apart individual Modulator bands are. The standard value is +63 (full range), negative
values effectively invert the order of bands.
Modulation destination “Filter2 Key Follow“.
