I've been working on a plugin for unity to allow users to create short loops from arrangements of other loops. Seems to be working pretty well, pretty much like a low-tech version of acid. Anyways, this was a little arrangement i made as a test, and i kinda like it so i thought i'd post it here for feedback and such. Feel free to use this loop for any project in any way, credit is not required.

Bass warning!a 13second sinewave, the tone sweeps up from exactly 20hz to 190 hz then stops. It was recorded in logic pro & i use it from time to time to do sub sweeps. If your speakers are loud please don't have them cranked up without hearing low first.

A patch with nonlinearcircuits jerkoff ("chaos circuit based on the jerk equation and its electronic implementation by jc sprott") in the center. I had a question that needed an answer. Is jerkoff a stable lfo when not using the input to disturb the rythm?my answer is. It can be relatively stable, but sometimes it is wobbling around. The recording is from a wobbly jerkoff. One output to osc cv in and another to a vcf vc in. The third output goes to a comparator. The comparator generates a trigger every time the cv is passing the threshold level.

Testing/documening my nonlinearcircuits timbre!. "this is basically a clone of the buchla timbre found in the easel. ". Sound:1. Sine wave not going throught wave folder2. Sine wave though wave folder3. Triangle though wave folder4. Square through wave folder5. Saw through wave folder. An lfo is modulating the bias. No, when going through the folder the there is never a sinus wave. . . Next time. . . Also it is a matter of calibration. I should check it out.

Doing a test of how this looks on this site. Triangle wave raising octaves in steps. Took 5 tries but got one that im happy with. If you notice at the end the color starts going backward when the frequency gets too high, instead of going towards red. (which is actually the opposite of the wave length ratios in the light spectrum).

Ff chaos test conditions:cv in from nlc jerkoff. Square wave in from lfo, 1hz. 3 vcos tuned to 130,8hz and one "strange sound". Cv in on vcos are attenuated, about 50%. Gate 1 and cv 1 to vco pan leftgate 2 and cv 2 to vco pan rightgate 3 to vco pan centertrigger to "strange sound" pan center. Sound 1 - cv min and rate minsound 2 - cv max and rate minsound 3 - cv min and rate maxsound 4 - cv max and rate maxsound 5 - cv at 50% and rate at 50%sound 6 - jerkoff to cv in on lfo. Vco 3 gets cv from jerkoff - chaos.

A drain after a water flow: the water seems to build up a physical-mechanic surface tension kept mass in the tube, opens and closes this bubble-entity producing a specific rhythm in the plughole resp. The drainage pipe. It pulses with various plops and splashs, starts off with a firework kind of beat but then one hears a differentiated rhythm of 4-strokes sequences with slugs before these etc. Getting slower. Many minutes later it ends (beyond this track). The (hearable) cut is just the censorship of a small abortive piece -- left in to document the recording as recording.

Warning! loud noise! this sound is not intended to listen to, but to do technical measurements!. This is a test recording i made to measure my headphone's frequency response. It plays a nice "left" and "right" to determine the channels. Then it plays back white noise first in both channels, then one at a time. Then the same with sine sweeps. Then short impulses.

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.
