69 Royalty-Free Audio Tracks for "Vcf"

Two filters playing a melody. The filters are uoki-toki polivoks vcf and intellijel μvcf.

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.

I let both the vco (intellijel μvcf) and the uoki-toki polivoks vcf play a little melody, the same. The vcf is in self-oscillation and cv1 at 100%. It does not track perfectly, but could be useful.

Sample and hold + vcf and manual filter sweeps.

Right channel the sin-wave. Left channel the output from uoki-toki polivoks vcf when i manually sweep the filter frequency. Resonance at max.

In the right channel you hear uoki-toki polivoks vcf. In the left channel is the sound of intellijel μvcf. They are playing the same tones. The sounds have the same envelope but respectively vca are also affected by attenuated lfos.

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. . . .

I made the vcf self-oscillate at a frequency of ca 270hz then i connected a sinus wave vco to cv1 and swept all the frequencies.

A little tune where uoki-toki polivoks vcf and intellijel μvcf are acting as vcos. I use one more sound source and that’s noise for the rhythmic sound. No sequencer. No midi. No keyboard. No over dub. Don’t know why i write this… it’s an nice experiment anyway.

A kick drum did to my psytrance project called sonicmancer. I use u-he bazzile, filter resonate envelope in a sine wave. Hope u enjoy. Send me the track u did using this. . . I wanna listen =).

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. . .

Sinus wave connected to the filter cv1 in sweeps sound from mfb osc-03some reverb from ladik d-330.

Test of how uoki-toki polivoks vcf handles sin-wave. I tune the module i use as sin-oscillator (intellijel μvcf) to ca 270hz. I connect it to uoki-toki polivoks vcf. I let a sin lfo sweep the filter, cv1 pot at ca 70%.

White noise --> vcf --> pcm out.

Strange modular bass loop. The file is loopable. Main modules is intellijel μvcf, uoki-toki polivoks vcf, synthrotek dirt and dinsync modseq. Thanks for dropping by.

A bass line created with uoki-toki polivoks vcf as sound source and doepfer a-124 wasp as filter. The wasp filter is modulated by dinsync modseq.

2hp osc is fm modulating bermuda (using fm in). Pitch cv to osc is controlled by sloth and attenuverter. The bermuda tri output singnal is shaped by doepfer vactrol vcf. The vcf is modulated by sloth (cv in 1) and jerkoff (cv in 2). The noise it from dan, going to polivioks vcf. Polivoks is modulated by sloth. Output from vcf is going to vca controlled by another sloth.

As the title says. . . Playing around. Added a beep and a sample. Works as a loop if anyone cant get enough :-d.

Sinus wave connected to the filter cv1 in sweeps sound from mfb osc-03some reverb from ladik d-330(i have modified my wasp filter to achieve more self resonance. ).

A modular synth composition.

Dark bass sound made with the following modules as main actors dinsync modseq, doepfer a-124 special edition, uoki-toki polivoks vcf, intellijel μvcf and synthrotek dirt. I'm exploring my filters and try to use them in different ways.

Simple beat in c.

A loop with hi-pass filtering in action!.

It is what the title says "modified doepfer a-124 vcf5 wasp filter"listen and you will understand ;-)i the middle of the sound/beat i turn up resonance. I have connected cv2 to the bass pitch signal. Funny effect.

Bubbly sounds from modular synth :-).

Same patch 3 drones. I let chaotic lfos control pwm and filter.

Some clips of my diy analog synth on the build.

Cross fm modulated filters performing a painful dance on your eardrums. This is noise but with a musical and rhythmic trace. I keep coming back to my vcfs…?.

Nice trick working with doepfer a-101-1 vactrol vcf. Noise to lp in. Gate to cvf in 1 out straight to mixer. Low frequency. High emph. Lp 0, bp about 5 and hp 0. Added a bass and my sampled voice. . .

Filter sweep with modded dirt filter.

Basically i connected one lfo to the polivoks in. Now when i think of it. Wonder if that added something…. And how much. And to cv1 i connected a square wave and to cv2 a wide frequency sine wave. Resonance at max. Think i have to reanalyse this patch later… i’ll be back!.

Or some acid sounds… and drone. All in oneused filters are> doepfer a-124 special edition, the wasp filter> uoki-toki polivoks vcf> intellijel μvcfdidnt plan to upload this to freesound, but read this. Okay filter freaks. . . The frequency analysis reveals a peak around 20khz. Through all of the track? almost. What is that? (when i converted the file to mp3 the peak disappears. . . ) one clue could be that i use the filter as vcas too?i have applied normalisation, compression and limiter in audacity. A "documentary" at https://www. Youtube. Com/watch?v=wtzfkg3mxcgin the film i use the mp3-file.

Classic modular sounds - i think. . . Sound sources are intellijel μvcf and uoki-toki polivoks vcf. A little reverb (ladik r-330) added.

Sinus wave connected to the filter fm1 in sweeps sound from mfb osc-03some reverb from ladik d-330.

Another beat. . . Made with my modular synth. But a beat is a beat. . . Or something. . .

Sound created by square wave lfos, attenuverters, hard synced vcos, delay, reverb and filter. I think it nice. Kraftwerkish. . .

A sound made usingalienxxx sound http://freesound. Org/people/alienxxx/sounds/343864/and my (gis_sweden) sound https://www. Freesound. Org/people/gis_sweden/sounds/344087/.

A loop. A dirty loop colored by dirt. This time edited i audacity. . . Compressor and limiter.

Drones made with an analog modular synth. The drones are generated by a generative patch.

Today i needed some techno sounds. Bmc drum, jupiter storm and wasp filter. Yes!.

A little something i made on my modular. The sound is a little edited in audacity.

An e50 morphing terrarium (digital) applying slow sweep filter/freq modulation of 8 voices. Cwejman vco-2rm (analog), synthesis technology e340 cloud generator (digital), and two lifewire audio frequency generators (analog). Mannequins three sisters vcf.

Creating slight variations in a simple beat with control voltage. All analog gear in my modular synth. Slightly "mastered" in audacity (normalization, compression, limiter).

It does not sound electronic in the way i like, but. . . Sequencing modular etc with fl studio. Totally noob!.

I'm trying hard to learn/understand nlc genie. Bought the module 3rd hand. . . At least. Some tribal sounds. Modulating genie w nlc sloth. Genie is modulating vco and vcf.

A modular synth experiment. 1 - noise/vclfo/slew - the brighter sound2 - noise/vcf - the bassy soundx - the bass drum is very unrandom. 5 minutes of random. . .

Very electronic. What else do you need to know. Do something with it. Let me know/hear :-) cut it up. Loop it. This is an unedited recording. (as usual. . . ).

Cool sounds from filter. The two filters filter a tri-wave. The filters are almost self oscillating and are modulated by an lfo. Natural tones. And some spring reverb and analog delay.

I'm trying hard to learn/understand nlc genie. Bought the module 3rd hand. . . At least. Some techno-like sounds. Genie and drum sound are modulated by nlc jerkoff. Genie is modulating vco and vcf.

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.
