10 Royalty-Free Audio Tracks for "Filter Self Oscillation"

Proper rainforest simulation this- a low-pass filter self-oscillating, with a lot of modulation, run through both a delay and a reverb. The result was not recorded off the mixer, but by means of a hand-held zoom h1n, giving it an ‘outdoor’ ambience.

Big room type kick drum created by processing a recording of filter self-oscillation from roland sh-101.

Test of how uoki-toki polivoks vcf handles sin-wave (ca 270hz) when the filter is self-oscillating. I bring the uoki-toki polivoks vcf to self-oscillation and tune the vcf to ca 270hz too. I let the lfo sweep the frequency. Cv1 pot at ca 100%. Hmmm interesting. . . .

A self modulated a-110. A self modulated bermuda through filter with some res. Barton analog drum, spring reverb and analog delay stompbox. Sxxxe (you know what) sound is imperfect wave forms, or. . . ?.

Don’t know if my english is correct. . . Butt i guess you get it, dear reader. Test of how uoki-toki polivoks vcf handles sin-wave (ca 270hz) when the filter is self-oscillating. I bring the uoki-toki polivoks vcf to self-oscillation and tune the vcf to ca 270hz too. I let the lfo sweep the frequency. Cv1 pot at ca 70%. What happens. . .

Test of how uoki-toki polivoks vcf handles sin-wave (ca 270hz) when the filter is self-oscillating. I bring the uoki-toki polivoks vcf to self-oscillation and tune the vcf to ca 270hz too. The vco is also tuned to 270hz. In this test i connect the same lfo to cv1 on the vcf and 1v/oct on the module i use as vco (intellijel μvcf). I let the lfo run. Cv1 on vcf pot at 100%. They are playing together. The vco is connected to the in on the vcf. Confused explanation. . . But at least not in swedish.

It becomes clear when i record with audacity and can actually see the attack and decay. I’m playing with alm pip slope. With this module you can cv control the attack and decay. As oscillator i use intellijel μvcf in self-oscillation mode. I fm-modulate this filter/oscillator with a tone from uoki-toki polivoks vcf. The semi random trigger is really two triggers connected to an or gate. Pitch is from analogue systems rs-40 (sample/hold and noise). I can listen to this for a looong time. Retro sound.

I want you to compare this sound with:"electronic minute no 18 - vcv rack sqr sequencing"https://freesound. Org/people/gis_sweden/sounds/413520/in this sound, no 19, i use my modular synth. The sound is not as clean as in the virtual one. To some extent i blame my method of recording. . . Different oscillators sound different. Here i use a self oscillating filter. That produces a clean sinus wave. The cleanest sinus in my rack. But i guess the real thing is not perfect and that is what you are hearing? in neither of the patches i use a quantizer. . . (that's art :-)and, i almost forgot, i use a cheap analog delay pedal. Noisy. . .

Version 2. . . Of https://www. Freesound. Org/people/gis_sweden/sounds/352940/. . . Or maybe version 34. . . . It's not better but a little different. More dynamics. Softer. But still i have the clicks :-/have to work on that. It becomes clear when i record with audacity and can actually see the attack and decay. I’m playing with alm pip slope.
