① "MIX IN 1~3" knobs
Adjusts the amount of audio signal inputs from ⑪ "INPUT 1-3" jacks. 3 different
audio signals can be connected, they can be summed and processed with VCF.
② "CUTOFF" knob
Adjust the �ilter cutoff.
③ "RESONANCE" knob
Adjust the resonance of the �ilter. When resonance is full, it self-oscillates and
can be used as a substitute for the oscillator.
④ "CV 1" "CV 2" knobs
These are two CV signal attenuators for controlling the �ilter cutoff. CV signals
are input from ⑨ "CV INPUT 1" "CV INPUT 2" input jacks.
⑤ "CV RES" knob
This is attenuator for the signal to control the �ilter resonance with the CV signal.
CV signals are input from ⑩ "RES" input jack.
⑥ "Q LIN" switch
Switch two different feedback path frequency linearity.
By switching "Q LIN" to "--", the resonance will not depend on the cutoff setting,
so the cutoff setting will have no in�luence on the Resonance setting of the �ilter.
Self-oscillation is possible down to frequencies lower than 1 Hz.
