@Joe did you ever achieve a satisfactory 1/x function? And did its intended application ever materialize?
I did embed a transfer function inside of a sample scanner as a bespoke unit. I think it worked OK as long as you understand and control the input to it, but I was never able to get the final end application to do what I wanted.
So I was also searching for a way to do the 1/x function. Specifically though I just wanted to create an equal volume mix of a couple of oscillators such that, when in phase, the total volume would never surpass 1 (10v).
I discovered this can be done using the RationalVca and hereās a working middle layer example. Iāll explain it in text though so it doesnāt necessarily need to be done in the Middle Layer.
 Create 4 oscillators and pass each into itās own level VCA
 Mix the level controlled outputs together at 1/4 gain.
 Sum the level amounts for each (giving a range of [0,4])
 Find the difference between the level sum and 4
 Place a rational vca after the oscillator mix and set the numerator to 4 and the denominator to the difference in the level sum.
 Celebrate.
The idea is that if all the levels are up (level sum is 4) then our ratio will be 4/4 and the signal will remain at 1. If only three levels are up (level sum is 3) then our ratio will be 4/3 and we will multiply the signal by 1.333 to get back to unity.
Hopefully I explained that well, it took me several hours to get right despite being deceptively simple
Edit: oh and hereās a video showing it in action https://photos.app.goo.gl/ZSKEkesvGcV4Rnmj6
Me Joe? I think one of those R values exceeded my IQ value.
Iām no Joe and itās not with the ER301 directly but I have been using the chaos functions (including that videoās specific equation) on the teletype (Which then goes back into the 301). Check it out!
CHAOS x


get next value from chaos generator, or set the current value
CHAOS.R x


get or set the R parameter for the CHAOS generator
CHAOS.ALG x


get or set the algorithm for the CHAOS generator. 0 = LOGISTIC, 1 = CUBIC, 2 = HENON, 3 = CELLULAR
Since I unfortunately have no experience with creating a spreadsheet in Audacity, do you think you could maybe upload the wav file or explain how to do it? Would love to also ābuildā my āownā 1/x unit
Itās already on my list to do for desolationjones, so Iāll just make it public here when I find the time to dust it off and polish it up. It was sort of a miniproject that was meant to be used inside another, so itās not quite in a functional state at the moment. It will also have some caveats with how it works, because of divide by zero thing.
thats amazing!
