Perhaps two of these circuits, one for pitch and the other for amplitude or timbre?Īs an entomologist, this topic got my attention and I went through the article of Vela-Pérez et.
#Audulus huxley truth how to
I'm not sure how to represent a four-quadrant direction for the walk. I am thinking that the external CV controls the speed of the walk, but the bipolar output only supports walking back and forth. Yeah, this is nothing like an ant walk, but you have to start somewhere.
#Audulus huxley truth Patch
It seemed to work best with linear can you explain how my patch could be changed to include CV of the curves (separately up and down are possible) to get what you describe? I tried this with a Joranalogue Contour 1 as the slew limiter, which has VC curves. Monitoring the FWR output, you see a spike proportional in height to the initial diff, which then ramps down to zero with an exponential curve. By adjusting the initial rates of the clock and slew, and the mix of the diff CV and the external CV, you can get a random slewed result that you can control the overall rate. This is mixed with an external CV for overall rate, causing the slew to move faster to match a greater difference. The result is a positive voltage proportional to the difference. I take the difference of the input and output of the slew and then full-wave rectify it. It's a straightforward clocked sample and hold, followed by a slew, but with one twist.
However, to have joining linear slopes, you would need a slew process whose slope can be CV controlled such as to reach each new step perfectly. You could also voltage-control the LFO, the mix of previous output with noise, and the slew rate. Slew the result with a linear slew limiter. Mix some of the output back into the noise being sampled to limit the step distance. Start with a typical LFO triggering a S&H on a noise source to make the classic random stepped output. The way you describe this makes me think of how it could be patched. I have Twin Waves and use those random LFO algorithms frequently. The additional control here is on the randomness of the rate deviation instead of the amplitude deviation. Just for completeness, the other random vector algorithm in the Twin Waves is about randomizing the rate in addition to amplitude. On the next step(s) it may however extend its movement in a similar of identical direction if the random draw makes it so. So the insect movement will never suddenly jump too far away (amplitude). This setting will define the maximum distance the insect will move (up/down) before a new random value is generated. Vectors are different from random S/H steps by moving linearly to the next level instead of a sudden jump.īesides a rate control, you have a maximum deviation setting. The algorithm that does it is called Random Vectors. The two LFOs in the Klavis Twin Waves can do that. Do you know of any random module that does something like this? (I remember Tides Parasite having a 'drunken walk'.).I would like to be able to generate control voltages mimicking these movements. I've been observing ants and other insects exploring surfaces.
