FILTERS knob
This is an important filter bank parameter that has the general effect of tuning it from from low to high.
It can also inuence the vowel tones, depending on the settings of Alpha and Beta.
Please note, the RA-99 filter bank is not designed for full cutoff, as in a conventional low pass filter.
FILTER CV jack
This has the same effect as the FILTERS knob, providing the option of voltage control.
Both the knob and the jack can be used simultaneously.
The resonance (Q factor) of the filter bank is not adjustable.
The filter bank can not be bypassed.
