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:

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

I can’t find this on the afterlater site. Do you have a url?

Thanks

There’s a crow script that could be repurposed easily enough I think. It’s in the Bowery git repo.

Looks like it has been scrubbed from their site and from ModularGrid. If I recall correctly, After Later never publicly stated that their take on the Benjolin was ever authorized by or licensed from Rob Hordijk. Perhaps that had something to do with it?

Looks like After Later Audio has rebranded to Calsynth. However no Benjolin seems to be offered at the moment.

I cannot recommend Fancy Synthesis Rung Divisions for shift register enough:
https://www.fancysynthesis.net/

It is a beautifully constructed module, that I get a ton of use out of in a pseudo-benjolin method. The Clock/Pulse divider is also underrated in this module and comes in handy for lots of different patches.

No rebranding that I’m aware of. After Later and Calsynth are just two of many modular “companies” making money selling clones of Mutable modules and other open-source projects.

didn’t know Bugbrand has a shift register. Looks very different from Double Knot

I have one of these and it is fantastic! So useful, so multifaceted. I use it with other Bug stuff as well as my Serge system.

And to follow up on my earlier post about the Juggler from After Later Audio, it was recently revealed on an episode of Podular Modcast that they are working with Rob Hordijk on a new version of the Benjolin. It sounds like this one will actually be licensed and stick around longer than the Juggler did.

is it something like a dual clock divider?

#106

Not quite. It’s two identical units. Each one is a digital shift register with 8 bits. It can shift/loop incoming data (hi/low) or internal data entered using a button. The data is output as 2 gates and also seeds 2 random CV outputs. The knobs control which steps are tapped for which outputs and a loop point.
