A variable-width bandpass filter with fast and tactile controls.
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.
Aperture works very well as a part of a subtractive synthesizer voice paired with your favorite oscillator as well as a signal processing unit. Use it as a Eurorack EQ by running drum loops or other program content with full a frequency range through it to help them sit in your mix a bit better. Pinpoint the exact instruments by dialing in on a narrow frequency band.
Drive your sound and add unique rhythmic content by adding some feedback. Sweep any one of it's parameters with direct CV control.
Aperture is a versatile addition to any Eurorack live performance rig as it is a great sounding filter for bass, drums, leads, pads, and entire mixes as an end of chain filter.
This is filter more unique than most standard multimode filters as it has both high-pass and low-pass filters ran in series. Each filter is independently controllable in addition to the macro controls that control both sides at once.
Aperture can be used in self oscillation as a screaming, wild sounding oscillator with it's 1V/oct input. It tracks 4 octaves or so. Not a precision oscillator by any means, but has a very unique tonal quality as it has two resonance points as well as feeback for the entire filter's circuit.
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
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.
at 1V/oct. This is the input for that.
In LVL: Input for CV control over the input
Freq: CV input for control over the cuttoff frequency.
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.
