Details

The Aperture is capable of simple filtering, self oscillation FM timbres, nasty acidic squelches, and capturing images of UFOs descending from the heavens on a cold winter’s night.  The concept is a bandpass that ranges from transparent to gnarly, with precision controls that behave under stress, all while being joyful to wreak havoc with. 

 

Features include:

  • Variable bandwidth via tactile and CV controls
  • Eight pole filter core
  • Independent resonance and self oscillation of both sides of the filter with CV
  • Feedback circuit with two modes and CV 
  • Input level VCA
  • Additional CV for opening the band either side of Center
  • V/oct tracking
  • Temperature compensated
  • Dry / Wet mix for parallel filtering sounds

Controls

*LEDs along the top indicate width and position of the filter

Knobs

Frequency: Controls the center frequency
of the band

Width: Controls the width of the band.

Freq CV: Attenuverter for the CV input for precise
control over the Frequency of the filter.

HP Res: Controls the amount of resonance on the
High Pass side of the filter.

LP Res: Controls the amount of resonance on the
Low Pass side of the filter.

Input Level: Attenuates the input level.
Unity at 12o'clock, total gain of 6 dB

Feedback: Controls the amount of feedback for
more self oscillation and squelchy behavior.

Dry/Wet Mix: You know what this means ;)

Width CV: Attenuverter for CV control
over the width of the filter.

Jacks

1V/ Oct: The aperture’s cutoff frequency will track
at 1V/oct. This is the input for that.

In LVL: Input for CV control over the input
level attenuation.

Freq: CV input for control over the cuttoff frequency.

Width: CV input for control over the width of the band.

FDBK: CV input for control over the feedback amount.

Input: This is where your audio signal you
want to filter goes.

Output: This is where the filtered audio
signal comes out.

HPCV: CV input for independent control over the
cutoff frequency on the high pass side of the filter.

LPCV: CV input for independent control over the
cutoff frequency on the low pass side of the filter.

HP Res: CV input for control over the resonance on the
high pass side of the filter.

LP Res: CV input for control over the resonance on the
low pass side of the filter.
