Knobcon 2023 DivKid Vids

video upload by DivKid

"All DivKid videos from my trip to Chicago, USA for Knobcon 2023"


1. 73-75 era Serge in the black panel 'Quasar' system // Prism Circuits at Knobcon 2023
Here we meet Sky from Prism Circuits who takes us through what he offers in the 4U Serge format, specifically taking us through his black panelled QUASAR system which uses classic 1973 - 1975 era Serge circuits.

2. Uncontrollable Rhythms from Moon Cycles and beyond // Pet Rock at Knobcon 2023
Here's Jonah from Pet Rock taking us through his sell out, sold at cost, first Eurorack module 'Pet Rock'. The module uses moon cycle data and random number generations to create two complimentary or drifting rhythms of varying step lengths and pattern densities. It's a fascinating concept that could lead to "good days and bad days" for your rhythms.

3. QV-L a POWERHOUSE of a Eurorack modulation source // Five12 at Knobcon 2023
Here's Jim Coker of Five12, of numerology and Vector fame, taking us through his new QV-L 'quad variable LFO'. It's a real powerhouse of a modulation module with 4 outputs, multiple clocking and frequency options, internal modulation, random generators, customisable control/performance options, syncing to the Vector sequencer for additional program changes and lots more.

4. NEW way to WAVETABLE! with Alias Zone & Osiris // Chris Meyer & ModBap at Knobcon 2023
Chris Meyer of Learning Modular & Alias Zone has A NEW WAY TO WAVETABLE!

Chris has been working on a new X and Y based wavetable systems that does two fascinating things, firstly it "samples" his whole large studio system while keeping that performable and responsive in the ModBap Modular Osiris and secondly he's using harmonics and interval sets to create morphing tunings within those sounds too.

This wavetable pack will be released for free through the ModBap site in the near future.

5. A Modular Approach to Eurorack Mixing with BARTENDER & BARBACK // After Later Audio at Knobcon 2023
Here we have several new modules from After Later Audio from Knobcon 2023. Lenny takes us through Bartender, Barback and Cast Iron which make up a new expandable, modular approach to Eurorack format mixing.

6. Simple solid clock sync! The Missing Link & ML:2 (Ableton Link) // Circuit Happy at Knobcon 2023
Giving the demo without any audio to listen to is a big move. A bold move made possible by rock solid behaviour from the devices from Circuit Happy. We have The Missing Link Junior and ML:2 Eurorack modules that are both Ableton Link enable devices for not just clock sync and reset but bar position aware behaviours for triggering and syncing to the patterns too. Impressive all round.
7. Better Spring Reverb! (with more filter features than your filter?) // Bubblesound at Knobcon 2023
It was great to meet David from Bubblesound at Knobcon 2023. I've been a long time user of his modules and he's consistently made quality modules over the years. The upcoming Spring Reverb module looks at Spring Reverb options in existence and aims to make them better, a fully featured SEM style multimode filter is on the module so you can really shape what's going into the physical spring, changing it's behaviour and sound. There's on board feedback which David is leaning into in this video too for more experimental patching.

"Includes Low-gain power and 9FB2D1B reverb tank, and comes in an 8u flight case.

Just been checked & calibrated (last week) by Charlie / Loudest Warning so all in top condition. Has the lights mod on the envelope generators.

I can’t imagine you’ll find a better example of this synth."

Latest Todd Barton Videos

It looks like Todd Barton's channel is the latest to be hit by my YouTube subscription bug. For some reason some of my subscriptions are not notifying me. If you are a supporting member and do not see your videos going up, please feel free to send them in. Not sure what's up with YouTube. P.S. If anyone out there works for Google/YouTube, please look into this if possible.​

That said, here's the playlist for the above:

1. NVO Sequences and Discoveries
2. Buchla 245 on THC NVO
3. Buchla 246 and 248
I just got this beautiful Buchla 246 Programmable Voltage Source built by Adam Scramstad. My all time favorite sequencer. There are two short maiden voyage explorations here. 1) Buchla 246 and 248 (MARF) and the second just the 246. This second one uses the 246 to take panning on a wild ride so maybe headphones or speakers. . .
4. BuchlaBot Lives
Soundtracks made on Buchla Music Easel, Buchla 200e Electric Music Box and Buchla 200. Enjoy!
5. 296e Env Followers meet Krell
Exploring sending lots of Envelope Followers out from the 296e Spectral Processor to many different functions inside a little Krell patch.
6. Pi Day Beat
OK, I'm definitely late to the Pi Day Party but couldn't resist doing something with those numbers, intervals and rhythm. Enjoy!

"paring the 4 oscillators of the NVO using the Buchla 292e as a 4 to 1 output mixer into the 296e Spectral Processor. All oscillators are being driven by the same CV from the 250e."​​​

NVO and Buchla 292e exploration

video by Todd Barton

"I'm fascinated here with the timbral richness provided by the different modes on the Buchla Quad Dynamics Manager, sometimes referred to as the Lo Pass Gate though that is just one of 3 modes. And the ever malleable pitch and FM intersections of the 4 oscillators in the Nested Vector Oscillator."

Serge 73-75 Homebuilt System 2020

Note: This site contains affiliate links for which it may be compensated.

via this auction

"Freshly built 73-75 system in a beautiful color scheme for sale. It's pretty much a standard build in random source boats except that it uses the elby jack color scheme, has dark brown knobs and has rca jumpers on the side to have the option to use the spring reverb as an effects send. If you want black knobs it's pretty cheap from thonk. I personally like the brown as it gives the system an organic look. :)

The system has rca jumpers on the side of one of the boats to allow for easy integration of the spring reverb as an effects send. You can choose to connect the spring tank directly to the pcb if you prefer and remove the jumpers. Either way, it sounds and behaves exactly like a standard build. Anyways, not an essential feature but nice to have extra options!

Also, I tried to show a couple places where there are some scuffs on the panel. Overall very clean. There are unused holes in the boat for R*S xlr power connectors that aren't being used with this build.

The connectors are for connecting the 2 panels together to take power from the top panel to the bottom one. The power inlet is at the top of the top panel, and there is a wall wart power supply to power both panels, which I will provide.

This is a great way to get into Serge and sounds incredible. Thanks for looking!"

Serge 73-75 Voice And Control

Note: This site contains affiliate links for which it may be compensated.

via this auction

"This is a 73-75 Serge system with 2 panels, the Voice and the Control. Both were put together from the eDIY sets that were offered at the end of the year in 2019. In addition, LEDs were added to 2 of the slews, the envelope, and the SSG modules. This makes a big difference when using, as it provides feedback. The 2 open holes in the control panel were fitted with toggle switches on the negative slews, so you can make them cycle. Both panels have been calibrated.

Both hammond boats are connected together by 4 screws inside, as well as a rubber grommet that provides a channel between the 2 for the power to be distributed. The panels were fitted with potentiometers and then wired to the boards, which took a lot longer, but this gives you flexibility if you want to do future modifications. In fact, I'd recommend someone diy friendly buy this if they'd want to add more toggle switches, LEDs, etc. The PSU is a frequency central power unit that has a +6 volt regulator, needed for this Serge design. Jameco AC adapter included to power both panels.

Cosmetically, this is listed as 'very good' since there is a little bit of rash under the mounting screws and a few small marks here and there.

Comes with a bunch of banana cables from modular addict of varying color and length."
