"Just got turned onto these cool modules from Infinite Machinery which is located here in my little town. Really digging them. Enjoy these brief test drives."
The Infinite Machinery Hexa VCA is a 6 channel VCA with DC coupling and a unique normalization function. All in 12 HP
Signal inputs are DC coupled. CV input response, 0 to +5V
Maximum amplification is unity gain, or 1.
Channels with no CV input will have CV normalized to the CV of the channel above. This cascading of CV values is defined in two groups, channels 1 - 3 and 4 - 6.
For example: If CV is patched to channel 1 and no CV patched into channels 2 & 3 - Channels 2 & 3 will follow the CV of channel 1.
Patch CV into channel 2 and nothing into channel 3 then channel 3 will follow the CV of channel 2. The same hold true for channels 4 - 6, with 4 being the start of the CV cascade.
"Curiosity is always my default. So . . . what if I create a simple single patch on the 700 FM Voice and scroll through the four Modes of each Algorithms? What sounds and textures will arise? Here's that scroll. Imagine the possibilities of adjusting just a single or multiple parameters? Sit back with a favorite drink for the next 7'30".

"Amazing the diverse and varied timbres and accent patterns that arise with a simple flick of a switch. We begin with these cross-modulated DUSG and both switches in 'Both' mode then explore combinations of Rise/Both/Fall switches. Enjoy!"
TipTop Buchla 264t – What is a quantizer anyway? video upload by Dexba
"We finally have a quantizer in Buchla form, but that poses some questions: what even is a quantizer?
Why is not called that? And how did they handle polyphony in modular 50 years ago?"

Message from the Mothership to all 200t users on Planet Earth!
We are thrilled to bring you the Quad Sample & Hold and Polyphonic Adapter Model 264t. The module is now shipping, and pre-orders are open at our dealers. Price: $265. [check with dealers on the right for availability]
Don Buchla designed the original 264 in 1970, but only a few were ever mad,e. This module features high-speed sample & hold circuits that can also switch to track & hold, delivering the exceptional performance you’d expect from a Don Buchla design. To push the boundaries further, Don added a groundbreaking feature: the Polyphonic Adapter. This was a bold vision at a time when polyphony was virtually unheard of, synth pioneer Tom Oberheim wouldn’t introduce the world’s first polyphonic synthesizer, the SEM, until 1975.
With the 264t, we’ve taken Don’s polyphonic concept one step closer to full realization. We’ve added ART outputs that can drive multiple oscillators equipped with ART, such as the 259t Complex waveform generator. Plus, we’ve incorporated built-in scales, adding a complete ART quantizer working seamlessly alongside Don’s original analog circuits.
"We present a lively and in-depth conversation with Todd Barton, "sonic adventurer, composer, educator and performer of abstract, freely improvised electronic music specializing in Buchla, Serge and Hordijk instruments." We discuss his connections to these instruments developed to become central to his music, and sharing his knowledge and experience with others through his popular YouTube and Instagram channels and private lessons. We also touch on a few encounters including the Serge anniversary show in San Francisco, the launch of the Buchla Red Panel series at NAMM, and most recently, his duet with Suzanne Ciani at Buchla & Friends 2025 in Los Angeles.

"I've been wondering how to approach this episode. If this were a module review, the 242 would not be able to stand up against modern 21st century sequencers. It's basically a 12 step sequencer with three rows of pulses so you can't even do a four on the floor. We need to remember we didn't have those in the late 60's, so let's not worry about that too much.
The classic pin-controlled 242 was custom made for CBS and it didn't carry the Buchla name. CBS (California Broadcast Systems) was licensed to build and distribute the 100 series and it eventually stopped because CBS didn't see a future for electronic instruments. I guess you need to have a long term vision, and CBS clearly had a different one. Regardless, the 242 is extremely rare. Fortunately, the 242T is not. Tiptop abandoned the pins and fancy illuminated buttons in favour of small buttons and a LED matrix. The 242t is a Tiptop first, and a CBS/Buchla later.
The 242 is a retro-futuristic trigger sequencer with some weird outputs. The ABC pulses are extremely short, but the alternating outputs are longer. Then, there's this SAW CV output which is tied to the master clock. There are start/stop and reset inputs and a CV controlled Period which is not unlike a frequency when pushed to audio rate. I tried to ping the 296 Spectral Processor with the ABC outputs, but these are barely audible. If you want to ping a rhythm on the 296, you'll need to use 281 envelopes and patch from there. Using them to ping a 292 vactrol is just wonderful.
Stazma and Todd Barton made excellent video manuals, so I am not going to explain the module in this video. Since nearly every Buchla module is either quad or dual, I used two 242 modules. I had to. Imagine it's the early 70's and it's the Dawn of Synthesis. We have no idea what the future will bring."
