FrEQ (Frequency)
St. Sub Oscillator (Stereo 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.
This effect is different from the equalizer in that you can add very low range
harmonics. You can also adjust the oscillator frequency to match a particular
note number, for use as an octaver.

a OSC Mode Note (Key

quency follows the note number or
whether it is fixed

number when OSC Mode=Note (Key

Note Fine –100…+100 Fine adjustment of the oscillator fre-
quency
c Fixed Frequency [Hz] 10.0…80.0 Sets the oscillator frequency when OSC
Mode=Fixed
Src Off…Tempo Selects the modulation source for the os-
cillator frequency when OSC Mode=Fixed
Amt –80…+80 Sets the oscillator frequency modulation
amount when OSC Mode=Fixed
d Envelope Pre LPF 1…100 Sets the upper limit of the frequency
range for which very low harmonics are
added
e Envelope Sens 0…100 Sets the sensitivity with which very low
harmonics are added
Envelope Shape –100…+100 Sets the oscillator’s volume envelope
