Octopass Poly Filter

8-Voice Lowpass Filter

Is an eight voice 24db/octave low pass filter based on the classic 2044 filter. All eight filters are fully analog with gain compensation of resonance and the lovely lush sound of classic synths. A global frequency modulation CV using a 3.5mm jack can be used to modulate all eight incoming CVs of the Polytip jack. The typical use is to patch polyphonic synthesizers with the use of only a few Polytip patch cables for its audio ins and outs and its cut-off frequency controls. To tap each filter I/O or CV using discrete modules the OCTO I/O module can be used as an expander. As there are eight filters in the module special attention has been given to power consumption efficiency.
