Modal Electronics designed 24dB per octave four pole transistor ladder filter, with some very unusual morphing characteristics or ‘polesweeping’, enabling transition from four pole through bandpass to one pole 6db per octave, or anywhere in between.
Features
Transistor ladder filter
2x Audio Inputs with trimmers
3x Control Voltage Ins with attenuverters – FM, Resonance and Slope
1x Audio Out
Slope control morphs the filter from four pole 24dB per octave, through band pass to one pole 6dB per octave
Transistor saturation Drive control
14HP
