Buchla Model 292 Quad Lo Pass Gates Eurorack Module by Tiptop Audio - Pics & Details

You've likely seen Todd Barton's recent Tiptop Buchla 292t videos. For those curious, the t denotes Tiptop Audio. Buchla clone modules are often referred to their makers by a letter: v for Mark Verbos, r for Roman Filippov of Black Corporation, j for J3RK, and d for Djangosfire. c denoted the original modules, and e new modules, by Don Buchla.

Details on the 292t via Tiptop Audio:

“It will be very interesting to see what can be done when light controls sound”. That probably was Don’s Buchla first thought when he saw the photo resistor. It seems it didn’t take him long to come up with a great idea using that electronic part and in 1970 he had already finished making his first batch of Model 292 Quad Lo Pass Gates. Why Quad? Because one was so awesome so four of them will mega awesomeness and if they can also be used to create quadrature speaker installations then hell yea!

Don really nailed it with the 292 and the way the lo pass gate provides a natural damping envelope to incoming audio is one of the greatest inventions ever made in analog audio.

Fast-forward to the year is 2023, and we are now very excited to recreate the legendary Model 292 again. In 2023 proper Vactrols are very hard to find, so we end up designing the Vactrols ourselves and the 292t uses 8 hand made Vactrols that are tailored specifically for LPG sound.

The first batch of 292t is now shipping to our dealers and pre-orders should open soon. We are very happy about it and as always are looking forward to see what you will do with them.

The user manual is already on the website so you can check it for more information. Our dear friend Todd Barton, who helped beta test the module, has videos on his You Tube channel worth looking as he explains the 292t in detail.

Vactrols will not stay with us for much longer: they are a very old technology that is getting banned in more and more countries due to the content of cadmium in them. So Don’s invention form 1970 needs to be reinvented for this century, and we are already deep into some serious experiments on alternative circuits that will help keep that wonderful sound of the low pass gate alive in the future. We hope to have this version available later this year.

And one last note, this coming May 11-13 Tiptop Audio will exhibit at Superbooth in Berlin. We have some products many of you are waiting for and some things that you never seen before, so stay tuned."

With Starlight In Their Eyes - Djangosfire Serge Improv Dec 2020

djangosfire

"'With the starlight in their eyes, they glimmer and shine - Set to cruise through the heavens, the Milky Way and beyond - Rumble shakes the capsule, as time between the past and the far off lead to wonder - To the Earth they say goodbye... with starlight in their eyes'

'Starlight in Their Eyes' 12-29-2020 Adam Scramstad/Djangosfire

I’ve been so busy past few months building DIY Buchla style modules... and I have NOT had any time to finish putting this Serge System together (its been sitting for way too long) until this afternoon. For me, the “test” of a system is when you sit down with NO patch cords (a blank slate) and start building a foundation patch.. then let it lead you into space. If I look up at the clock only to realize a few hours have past... well, then it all A-OK! Cheers - Adam"

"Sometimes I'm just compelled to Sequence! The Easel is clocking the custom Serge 4x8 Sequencer built by http://lowgain-audio.com. The custom Soundplex Serge panel was built by http://seeholzerengineering.com and Easel clone by djangosfire.

Melodies on a Buchla 200e - Part 01 Djangosfire

Published on Apr 26, 2019 djangosfire

"Wanted to show an example of melodic possibilities on a Buchla 200e. This a focus on the concept of pitched transpositions (not the tone of the patch this time).

Modules used:

Buchla 251e, 223e, 281e, 292e, 206e
Studio H: 258e & Control and Signal Router

A few notes on the pitch aspects of the patch:

- 258e is tracking 1.2v/oct
- 251e is tuned to play octaves
- the 223e is tuned to play a Major scale
- the Studio H Control and Signal Router is mixing and buffering the all of the CV into the 258e

Repeatable, pitch tracking on a Buchla 200e is possible, and sounds amazing! Once you set up a patch like this.. anything is possible.

More later - Thank you, Djangosfire"

Buchla Flute Feedback Patch clip

Published on Jan 22, 2018 djangosfire

"Late night weirdo patch on the Buchla - featuring the 218e + Grayscale DAO + 230r + 281e + 292e + 206e .... into reverb.

I might experiment and develop this patch, for now though... just a quick clip to help me recall these tones.

218e is massively fun and a deep expressive interface, and so fast to patch!

Thank you for checking out my noise :)

BUCHLA 285E FREQUENCY SHIFTER FEEDBACK & 296E - Examples 02

Published on Jan 13, 2018 djangosfire

"Today I’m further exploring a Todd Barton suggested 285e feedback patch found here: [posted here]

And am extending the idea to include a 296e!

Basic patch setup:

- 285e Down Output into 285e Signal In
- 285e Up Output into285e FM Input
- 285e Down Output patched into 296e ODD Input
- 285e Up Output patched into 296e EVEN Input
- 296e Spectrum Transfer set on to both ODD to Even, and Even to ODD
- 296e Display set to Envelopes
- 296e ODD audio output patched to 206e Channel 1 Left
- 296e ODD audio output patched to 206e Channel 6 Right
- I patched 296e Envelope Out CV from channel 15 back into the 285e Frequency CV jack

Audio from this video was straight out from the 206e main, through the console, into DAW (which I used some UAD EMT Reverb).

Now, go explore some sounds!!

Cheers,

Melodic Slurs Buchla 200e and DAO

"'Melodic Slurs' Buchla 200e and DAO improv.

Main VCO is the new Grayscale DAO "Dual Algorithmic Oscillator" - a Buchla format module build and sold by Grayscale:

http://grayscale.info/buchla/

More exploration! Actually, I was just enjoying the tone of one of the SYNC setting for one of teh 2x VCO's! - The main sequence is from the 250e in a sort of "quantizer" setup... with a S&H patch on the 266e controlling what stages of the 250e. I used a 254e to mix and offset voltages from the 250e and the 218e.

Outputs of the Buchla are patched into the AKS, then patched through the Synthi eq and spring reverb.

Cheers! - Djangosfire"
