ADDAC System has released a series of videos, demoing its ADDAC702 Dual Voltage Controlled Filter.

It’s the company’s first voltage-controlled variable filter, inspired by the original Korg MS-20 filter.

Features:

  • Two independent filters, a High-Pass and a Low-Pass with dedicated audio inputs and outputs.
  • Besides individual outputs the HP and LP are also sent to a voltage-controlled Mix between the HP and LP filters.
  • Both Cutoff and Resonance are voltage-controlled with dedicated cv attenuator pots.
  • Switch for selecting between normal cutoff behaviour and an adjustable Smooth circuit to simulate a vactrol behaviour for cutoff control.
  • Switch for setting filters Filters in Parallel, independent, or Series: HP into LP.
  • Inspired by the Oscar synthesizer we added a Coupling switch to tie the HP Cutoff control to the LP Cutoff control, in this case the LP cutoff controls act as an offset from HP setting.
  • Three position switch selects different resonance clipping paths: diodes / no clipping / leds.
  • Both filters features a post Distortion/Fuzz circuit that adds extra harmonics adds an even deeper growl or extra gritiness to it.
  • All audio outputs HP, Mix and LP feature a switch for choosing phase output, allowing additive or subtractive mixes.
  • Three LEDs monitor the amplitude of the three outputs: HP, Mix, LP.

Here are the official demo videos: 

The ADDAC702 Dual Voltage Controlled Filter is priced at 370,00 Euro. See the ADDAC site for more info.
