it powered at test but and no shorting, still missing 2 logic chips (in the mail)

My typically-deleted Digikey newsletter had this lovely article in it today; definitely going to build one of these ASAP…

sadly, i believe my shift register to still by dysfunctional despite replaced susceptible logic chips that were definitely blown.

analog dysfunctional shift register!

Keith Fullerton Whitman, on The Wire:

The recording set-up for the Generator and Generators albums

“I found a quick cheap and dirty way to make these neat little canons, little Bach-like motor rhythms, very straight, 16th note, 8th note, pulsing, beautiful sounds. It’s a very small part of the patch, it’s just like four oscillators, the slow one doing the rate of the melody and the other one doing the clocking of the melody, going through a quantiser. Simple, just a few modules. And then I play with that for a few weeks, and I’m getting good results. Detuning each oscillator so there’s static intervals in there, like static third, static fourths, octaves of course. And then I got to a set of rules within the piece the more I played with it.

“It was almost like the exploration itself dictated the piece more than I was as a composer. I was sort of thinking what kind of results can I get from just using this very simple small thing. And then I found a way to have the whole thing be in this loop where the first oscillator the pitch was being analysed, and then was controlling this whole other group of things, so it’s taking the seed from this one reciprocal thing, and then feeding it into another patch, and that got really interesting. Sort of like, this is going half the speed of that, so it’s kind of accurately tracking this, but not successfully, so you get this ghost in the machine thing, where little bits of that were just off. Or it was maybe making a bad decision guessing what that was doing, feeding like polyphonic material into a monophonic pitch shifter. You play an octave pedal and you start geting those blrlr-blrlr-blrlr kind of things? OK, this is really cool!

“And then very slowly built it from one tiny little case with just eight modules, then one suitacase, then two suitcases, and then it just got ridiculous. In one year it went from the string quartet to like the Vienna Symphonic version of it. It’s no better, it’s just gets more complicated with the same tonality. And then I had drums, I was having this kick drum every ten beats, and hi-hat every, like, 17… it was getting like prime number things, it was getting Prog. It was Pentangle turns into Genesis.”

okay so I Did This Thing. per @Starthief and @grey, here’s how it goes:

Timerunner sends master clock all over the place (those are 1:3 headphone splitters I got on eBay ages ago for cheap mult’ing, mult’d to Links, etc), sine from Batumi to Marbles (in SR mode), to Stages (6-stage SR), to Telephone Game (3 stages + Sum, and has a clock thru for convenience). so it’s a 12 + 1 stage ASR.

Using internal envs and VCAs where possible for simplicity, Tides to LxD, Braids n Plaits triggered internal envs, Rings struck by change in v/oct. Braids has a little “meta” voice changing going on. I tried it with Plaits model switching too but that was Too Busy. Kick from Peaks. One stage also controls Jitter on Marbles for occasional you know jitter. Timerunner contributes additional rhythm trigs/gates.

here’s a lil ditty:

this was a neat experiment as it got me somewhere with a patch design consideration as my jumping off point, regardless of whether or not it “works for me.” amazed I have three different ASRs and “if this was My Style” this is a fine place to start. interested to see how I pull this apart and back into something.

Reviving this topic - while researching a Norns project I stumbled across these videos of Rob Hordijk talking about the rungler circuit:

and I’m kind of obsessed.

I’m particulary interested in the way that the rungler uses a shift register to control timing, as well as pitch - that’s a step beyond what I’ve done so far. I’m also trying to wrap my head around its stability - it doesn’t seem to me like the phase of the two oscillators would produce repeating patterns reliably, but I’m not great at analog circuits.

Does anyone here use a Benjolin/Blippoo box, or other rungler circuits (or a full Hordijk modular)? I’m curious to what extent you can get it to blend/integrate with a larger system, and whether it has been a fruitful source of inspiration, or more of a one-trick pony?

Whooa, thats impressive! I’ve been looking for an excuse to build a banana benjolin for my setup.

I had the Metalbox one in my Frac rig for a while, around a decade ago (based on the CGS/Ken Stone PCB). I bought it mainly for cascading sequences with different VCOs, BUT even when running the pitch CV input through a quantizer first, the voltages it output were NOT 1v/oct and therefore the resulting sequences just sounded drunken, and so I sold it. :slight_smile:

http://www.elby-designs.com/webtek/cgs/cgs34/cgs34_asr.html

whooo this is an old thread! one simple way to integrate a benjolin in a larger system is to use vco b pulse out as master clock for the rest of the rack!
i usually do this with makenoise tempi and then distribute division\multiplications.
this way not only the benjo is in time with the system, but,if you rungle vco B itself, you can have very chaotic global timing variations :slight_smile:

p.s.: hello @Gregg giona here :smiley:

Good morning.

I’m trying to build out a eurorack facsimile of a Benjolin using a Fancy Rung Divisions.

My understanding is that I would need two oscillators. One oscillator plugged into the CLOCK input of the R.D. and one oscillator plugged into the DATA input.

Both of these oscillators would run into a mixer then into a filter then out to hello world.

I guess my question is what do I plug the shift register OUTS into and what do I plug the rungler OUTS into?

I am a novice.

Thanks for considering.

In the schematic for the Rungler below, the CV output in the bottom right is the sum of the three shift register outs that are summed through a crude digital to analog converter. The Rungle CV is then sent to the FM inputs of both oscillators and the filter. So with your set-up you would use the Rungle output of the Rung Divisions into the FM inputs of your oscillators / filter to emulate the typical benjolin routing.

hey, it worked! Thanks for the tip.

I just picked up a DIY Benjolin clone I hadn’t seen before - Juggler by After Later Audio, very nice panel layout. I wasn’t sure how it fit into my rack, but really loving it as an audio source, CV source, and a “clock” for Marbles, just as @hyena suggested:

It feels like it is letting me open up a lot more negative space around Marbles’ melodic lines; very interested to see where this goes.

I’ve been thinking again about this patch the past few days and wondering how hard it would be to create something similar for Norns?

An LFO into the sample in of a clocked S&H, with a quantized output being fed into an ASR into 3 vcos.

Page 1: lfo speed, shape, depth, clock speed
Page 2: vco shapes, root notes, volume, fine tune
Page 3: quantizer scale etc
