Aperture is a bandpass filter that has various controls and can produce various tones. A normal bandpass filter controls the band passed by the frequency knob, but in Aperture, how much is centered around the band specified by that frequency knob.BandwidthIt is also possible to control the frequency of (WIDTH control).
This bandpass filter is configured by passing both a 4Pole lowpass filter and a highpass filter. The cutoff of the lowpass filter is the upper limit of the band, and the cutoff frequency of the highpass filter is the lower limit of the band. Of these lowpass / highpass filtersTwo resonances can be controlled individually by knob and CVis. The cutoff can be controlled by CV.
It also has feedback that allows you to select two modes with a switch, INPUT LEVEL that you can get distortion by boosting, Dry / Wet control that you can mix the filtered sound and the original sound, etc.Control everything even with CVAs a result, it is possible to produce a wide variety of tones.
