Funkstill released Filter Threek 13700 Analog Morphing Multimode Filter


Funkstill Filter Threek 13700 is an analog morphing filter module with 12 available operation modes, a built-in matrix, and a very characterful sound.

The Filter Threek 13700 is an OTA-based analog multimode filter that offers two serial linked multimode circuits. The first can be operated in a high pass, bandpass, lowpass, or all-pass mode with a slope of -12dB per octave. The second filter circuit is a high-pass or lowpass circuit with a slope of -6 dB per octave.

The Filter Threek 13700 is an analogue, 3 Pole Morphing Filter with 6 steplessly variable and voltage controllable modes. It provides self-oscillation, wave shaping (between the modes) and a lot of modulation possibilities: VC-Mode (continuously), VC-Resonance, Linear FM, two assignable CV inputs and more. It is a low distortion filter, which develops its rough character through the various modulation and feedback possibilities. Especially if you modulate the Mode at audio rates for example with a VCO or by feeding back the output signal to the Mode input (CV1, Out > Mode) you can explore very unique und dynamic sounds. With the additional 1 Pole input and 2 Pole output there are 12 filter modes available. The module is compact and user friendly at the same time.

Operation Modes

3 pole output:
3LP: Low pass characteristic with a slope of -18 dB per octave
2L-1H: Bandpass characteristic consisting of 2-pole low pass and 1-pole high pass
1L-2H: Bandpass characteristic, consisting of 2-pole high pass and 1-pole low pass
3HP: High pass characteristic with a slope of -18 dB per octave
1L-2A: Combination of 2-pole all-pass and 1-pole low-pass
1H-2A: Combination of 2-pole all-pass and 1-pole high pass
2-pole output:
High pass, bandpass, low pass or all pass characteristics with a slope of -12 dB per octave. (Depending on the 3-pole mode selected)
1-pole input:
High-pass or low-pass characteristic with a slope of -6 dB per octave. (Depending on the 3-pole mode selected)

With the mode toggle switch on the module, you can manually change between the bandpass types and all-pass combination. This process can also be controlled via CV. Good to know is that it is also possible to use the filters individually with the 2-pole output and 1-pole input.

The highlight of the Filter Tweek module is the continuous morphing between the different filter modes with the mode knob thanks to the diode circuit. It can also be modulated via CV and goes far into the audio range. Check out my first look to get an idea of this feature. In the center position, the signal is inverted and the filter produces lovely distorted sounds.

Price €320
