Product description "After Later Audio - FILThy"
FILThy is based on the CEM3320 chip known from synthesizers like the Pro One or the Oberheim OB-Xa. LP, BP, HP and Notch are available simultaneously as taps. On the input side, two audio signals as well as two CV signals for frequency modulation of the filter and one CV signal for controlling the resonance can be applied. The parameter FM1 has a polarizing attenuator and resonance has a simple attenuator. The filter can be set to self-resonance and tracks 1V/Oct signals well.
