49 Royalty-Free Audio Tracks for "Vco"

Modular j3rk dual mirro core vco kick bd.

Xor exploration.

This sound was made with 3 lfos, 1 vco and 1 vca. It was decided that the sound should be 30s. It took some tries for me to set the lfo that controlled the vca. The vca controls the output amplitude of the sound.

Modular synth patch with 2 voices (vcos). One sinus wave and one triangle wave. Max reverb (hall) on my ladik d-330. Output to reverb is mono. Observe how the output from the reverb makes affects the channels. Meanless and bizarre video on https://www. Youtube. Com/watch?v=daymdm8vrz0.

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.

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.

Simple 4 quadrant multiplier done with a lm13700 and some components.

Warning: harsh noise with resonant malefactors. Bad q ! bad q!. Noise sound through analog phase shifter and steiner parker filter through a holtech-based delay. I imagine this as a soundtrack to an ultraviolent horror movie scene.

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%.

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. . . .

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. . .

Self modulating a standard doepfer a-110 vco. We are listening to a square wave. I'm modulating with a sinus. I'm wiggling pwm and the degree of self modulation (and attack and decay). Spring reverb and analog delay from stomp box.

Aha! the wave form effects the wave color! here is a 60hz tone playing alternatly sinus and triangle wave. In this test im using vco-1. #colortest.

What effects the color of the wave here on freesound? i could ask, but here is a little test. Part 1 - a (about) 60hz tone going from sinus to triangle (vcv-rack vco-2)part 2 - same tone. Sinus wave. An accelerating vibrato. Part 3 - now 2 tones. Same 60hz sinus tone plus another sinus tone slowly increasing in frequency creating beating effects. The second, rising, vco has a lower amplitude. All three part has the same peak amplitude (-4db)#colortest.

Some clips of my diy analog synth on the build.

I use a voltage controlled lfo (vclfo) for this experiment. When i send a trigger to the lfo it resets and start over again. In this example i'm using a sinus wave output. I send the output, the sinus wave, to1 - a sample and hold (s/h) module2 - a quantizer3 - straight to vco. The s/h and the quantizer are triggered at the same time. Even an envelope a generated with the same trigger. All three sounds are controlled by this envelope. First out we have s/h (left)second straight to vco (right)third the quantized (center). As usual its fun to take a real close look at the wave!.

Sample of the doepfer a-110-1 rectangle output. Pulse width is set to around 50%, so it should roughly be a square wave. Here's a link to the module: http://www. Doepfer. De/a110. Htm. Captured using a rme babyface and cubase.

Sample of the doepfer a-110-1 sine output. Here's a link to the module: http://www. Doepfer. De/a110. Htm. Captured using a rme babyface and cubase.

Sample of the doepfer a-110-1 sawtooth output. Here's a link to the module: http://www. Doepfer. De/a110. Htm. Captured using a rme babyface and cubase.

Sample of the doepfer a-110-1 triangle output. Here's a link to the module: http://www. Doepfer. De/a110. Htm. Captured using a rme babyface and cubase.

Its a sine wave folded 4 times by a cgs inspired wavefolder module (kinda like the metalizer from the minibrute). The whole thing is then modulated with an external function generator that controls amount and frequency of modulation. This is what came out and it's pure junky drone noises, so goddamn nasty. Absolutely love them. Feel completely free to sample this and use it for your own purposes. This is a diy synthesizer i'm building and unfortunately it is still a prototype, but i'm gonna finish it soon and hope to sell it. Cool indeed, isn't it?.

Drone sounds generated with the black wavetable vco.

Small but nice drone patch. Will try to replicate it on my physical modular.

Kick from my first sample session with my fresh eurorack:- envelope generator: make noise maths- oscillator: doepfer a-110-1 vco- filter: doepfer a-124 vcf5 wasp.

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.

Cicadas from hell. 6 pulse waves (cwejman vco-2rm, two audio frequency generators, and instruo cs-l), frequency/filter sweep modulated by e350 morphing terrarium. Overall frequency shifting by an e520 hyperion effects processor.

A dark/eerie alien-like atmosphere for background ambiance. This sound was created using my modular synth, more specifically the black wavetable vco from erica synth and a mutable instrument clouds.

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 pure synthetic loop made from a sine. Sawtooth vco. This a crossfaded infinite loop i use as a humming background in my s. W. Lightsaber replicas. Rich in bass & ring-phased choruses. Enjoy & rate it ! ;).

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.

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.

Same patch as in electronic minute no 226 and 227 but on my real modular. I'm using a filter. Thats why i call this version subtractive. I'm subtracting harmonics from a square wave. Why are 226 blue? probably because i did it at work. . . Listening in bad earbuds. Makes you rise the bass. Lets see if i can make this wave ble at the end! i will slowly fade out the vco with high pitch. At the very end i'm switching the synth off.

Sound of a teleportation device. This sound was created using my modular synth, more specifically a black wavetable vco from erica synth and an mutable instruments clouds. Going through a focusrite scarlet 2i4 and finally, through pro tools.

I used make noise function, doepfer a-147-2 cvlfo, doepfer a-148 sample and hold, doepfer a-110 vco, doepfer a-124 filter, alm tangle quartet vca and mixer, doepfer a-199 spring reverb, pittsburgh modular outs (mk. Ii) outmodule.

Start with chaos. In this sound/patch you have the possibility to enjoy chaos and feedbacki use my sloth lfos and jerkoff - another chaos moduleim possible sick i like this - thou its simple. Sloth modulate vco and filter cut of frequencyfeedback from vco to the filter via a vca controlled by a looping envpan fx also controlled by sloth - same env that controls the frequency. The "prassel" rustle sound is great in my earsjerkoff, exp vca, function and another sloth. Evaluation of patch/soundone cycle is - there are many cycles to consideronly short sounds - no, goodamplitude variation - yep goodpitch variation - mediumtimbre variation - some, via filter/two soundsmusical value - i think so!entertaining - yes?!.

Zlob diode chaos. X output - pan left "alto voice"y output - pan right "soprano voice"z output - pan center "bass voice" (no cv input to vco)trigger out - controls noise. This is a recording that makes a chaos explorer happy.

Thought i wanted to explore fm-modulation a bit further. The sound is going through my ladik reverb. The vco i'm fm-modulate is the intellijel μvcf. A filter really. . . No editing in audacity. This is the result. Sorry for long sound. . .

Same patch as in electronic minute no 226 but on my real modular. I'm using a wave folder. Thats why i call this version additive. I'm adding timbre to a sinus wave. I will do an subtractive version next.

I'm trying hard to learn/understand nlc genie. Bought the module 3rd hand. . . At least. Trying to replicate the sounds from andrews demo videos are to learn. 2 tri lfos to in1/2 and in2/3. Out- to wave folder and out+ to cv in on vco. The bass drum like sound is another story. But modulated by a nlc sloth. . .

Bartonmusicalcircuits 2lfosh (bmc 017). Manual wiggling. First it acts like a sample and hold and lfo. S/h connected to a vco and the lfo to a filter. Then i'm testing the lfos. After that you hear the two oscillators. Great module. 3 in one. Lfo, sample and hold and oscillators. Square, triangle wave and a mixed waveform!.

Zlob diode chaos - selection from an hour long recording, 54min and 45sec in. The chaotic lfo has 4 outputs x, y, z and trig (trig-ich. . . ). Center sound: x to pitch cv in on vco, y to filter cut of. To the right: z to a wave folder (osc static pitch). To the left: trig to cv in on a self oscillating filter. There are peaks (hz) beyond my hearing. I hope you can manage. . .

A third version of https://www. Freesound. Org/people/gis_sweden/sounds/352940/. Now i let the alm pip slope affect a filter. I play a little sequence made with cvlfo , clock divider, attenuverter, quantiziser. The way i usually do…. But the interesting thing is the cvad (?) voltage controllable envelope generator. But in the case of alm pip slope you just control attack and decay. Seems to be enough. As in the other versions of this sound i connect one lfo to attack and a second lfo to decay. But this time i connect the vcad to control the frequency of a filter. Interesting. I wish i had two more cvlfos… should open up for rhythmical usage. I use no vca or adsr. I have connected the vco straight to the vcf and the vcf to mixer. In the beginning i have the frequency pot at 2 a clock then i gradually move it clock wise and let the vcad take control. 1 minute in the pot is fully clock wise. The vco is playing a sawtooth wave. If you dl and inspect the wave you can see that in the beginning and the end it is a sawtooth wave, but in the middle part the filter affects the wave form.

1 looping envelope and 2 vclfos in a dance (chain connected). I think its harder for this combination to find a nice pattern - equilibrium. It happens sometimes. Maybe the mixture between positive and negative cv confuses the modules. Makes it harder. I start the recording with one of the vclfos in vco-mode. After about 17 sec i swith to lfo-mode. Records and hope that a pattern should emerge. I have been listening, and looking at the wave form, in different modes, but i'm not sure if there is a pattern in this recording. . . Maybe to advanced for me. There is - some -sort of pattern repeating every 22 sec. Or?.

Created by divkid for use in the make noise soundhack morphagene. There are dry-only, fx-only, and mix versions of this reel in the pack. See it in action at https://youtu. Be/rk4ufmfcouc. Patch walkthrough. The patch starts with the qu-bit chance providing discrete random values (sample and hold) going into an instruo harmonaig. This takes the stepped random voltages and quantizing them to a given scale. I put in the notes c d eb f g ab bb which is a c natural minor scale, the relative minor of eb major (for anyone that's curious). However like most of my modular work i didn't actually tune the oscillators to anything specific. So treat the scale as a pattern of intervals not a set of specific notes. The quantized notes then form 4 voice chords giving us a root, third, fifth and seventh cv output that will be diatonic following the scale pattern, meaning the third will be major or minor, the seventh major, minor or dominant and the fifth natural or diminshed to suit the scale. With the 4 quantized outputs on the harmonaig these all go into the four oscillators on the synthesis technology e370 quad morphing vco. Each of the e370 oscillators are in the basic morph xy mode using the built in rom b set of wavetables. Wavetables are modulating by various mixes of the befaco rampage, mutable instruments tides, wmd multimode envelopes and music thing modular turing machine. The modulation sources are mixed and split with multiples and mixers. These modulating wavetables then go into a bubblesound vca4p where i'm using 4 mk1 intellijel dixie oscillators all un-synced and free running with sine wave lfos. Each lfo freely fades the voice in and out of the vca4p. As this is unsynced there's no regard to pitch changes linked to changes in amplitude and the swells. I find splitting the gate/rhythm from pitch regarding sequencing to be a freeing and interesting way to work that's not available on traditional instruments. This is just a simple application of that idea with the lfos fading freely unrelated to the other modulation or sequencing of pitch. The sound then goes from the vca4p mix out into a befaco mixer and praxis snake charmer which the output section of the larger case and i'm sending a 'pre' auxiliary out into my fx case. The dry sound first goes into the erica synths fusion delay / flanger vintage ensemble which is giving me short modulated delays giving vibrato like sounds and pushing the input level and overdrive gives us some warmth and grit that thickens up the sound and also fills in the gaps left by the free running lfos pulling quieter sounds and compressing in the on board tube. This then outputs to the feedback 1 bit multitap delay module which has it's delay chip pushed to longer times for some added crackle and noise. I'm using the two delay taps for a shorter and longer delay with little feedback to mix the dry sound for a generally noisier and smeared version of the input. This then goes into the xaoc devices kamieniec with it's on board lfo as slow as possibly for a mildly resonant phase shifting. This goes into mutable instruments clouds set to sew random grains slowly and randomly which are pitch shifted up 2 octaves to fill out some high end flourishes against the closed chord voicings at the core of the patch. Finally this goes into a long lush reverb from the halls of valhalla card in the tiptop audio z-dsp. The stereo fx chain and the mono dry signal are mixed in the befaco hexmix and recorded as a mixed stereo file. I'd consider this to be the main 'reel'. However i split the dry signal and the fx only wet stereo signal and recorded those at the same time so you can choose which reel to use and experiment with dry/wet or blended sounds from this patch.
