10: Sub Oscillator

10: Sub Oscillator

This effect adds very low frequencies to the input signal. It is very useful when simulating a roaring drum sound or emphasizing powerful low range harmonics. You can also adjust the oscillator frequency to match a particular note number, for use as an octaver.

a: OSC Mode

The OSC Mode parameter selects the oscillator operation mode. When Note

b: Note Interval

(Key Follow) is selected, the oscillator’s frequency is determined based on the

b: Src

 

note number, allowing you to use it as an octaver. The Note Interval parameter

c: Note Fine

sets the pitch offset from the original note number by semitone steps. The Note

 

 

Fine parameter allows you to fine-tune in steps of cents.

The Src parameter is fixed to the Note #, and you cannot select another source.

d:Fixed Frequency [Hz] The Fixed Frequency parameter sets the frequency when you select “Fixed” for the OSC Mode parameter.

e:Envelope Pre LPF This parameter sets the upper limit of the frequency range to which very low harmonics are added. Adjust this parameter if you do not want to add lower harmonics to the higher range. For example, you can create a nice effect by add- ing very low harmonics only to the bass drum sound, not to the snare sound.
