According to guyd2, the Model 416.3 Meta Expander is:
"A sophisticated, stand-alone expansion unit for the Buchla Music Easel.
Contains several dedicated modules : Comparators, Dividers, Boolean, VC Slew Limiter, S/H & Noise, analog ultrastable VCO/LFO, advanced Mixer w/ Comparator, and an 8-step Sequencer.
Also expands on the 208 CV I/O's, pulses I/O and Switch inputs."
"*700 Function Processor is now officially released.*
This video showcases the latest *Pattern_Seq* app included in the production version.
This is a quick walkthrough of the main features and functions of Pattern_Seq.

700 Function Processor Patch #1 | One Module, More Patch Space

"Testing the TipTop Audio / Buchla 248t module. The 248t has eurorack level CV/Pulse outputs as well as the ART serial data outputs to drive modules that will receive ART note data. This configuration has a TTA 259t controlled by the ART signals and the Buchla 208c Easel Command controlled by CV/Gate (v/oct scaling).
"The Tripple sequencial Voltage Source card (TSVS) is modulating the following: top seq - pitch Complex Oscilator, mid seq - Timbre amount, lower seq - MO frequency modulation amount.
208C sequencer triggers the envelope generator"
"A piece combining field recordings with the Prophet-10 and Buchla Music Easel. Listen for the wind, quiet spaces, and birdsong weaving between the synth textures.
Prophet-10: Recorded with blueSky reverb; an extra layer of reverb is added in the DAW with Raum.
Buchla Music Easel: The sound is first treated in LOSSY, then sent through the MOOD MK II for additional reverb, along with the Easel’s own spring reverb. While playing the LEM218 keyboard, I adjust the 208C Lo-Pass Gate level for dynamics.
The field recordings were captured in a forest somewhere in Tokyo."
"The BOSS ME-50 is one of my favorite effects units — simple, expressive, and still inspiring after all these years.
In this setup, I combine the 700 FM System with the Buchla 208C in a four-voice configuration:
One voices from the 700 go straight into the Auratie (fully wet).
One more pass through the 208C’s LPG .
The 208C main output runs through the ME-50 to shape the core sound.
The other two voices pass through the Auratie
In this patch, I use the ME-50 for distortion, modulated pitch effects, and a spacious delay that blends with the Auratie
This is a cross-era collaboration: vintage guitar effects, FM synthesis, and West Coast analog character blending into one ambient/experimental performance."
"Multitrack recording of the Buchla Easel Command (model 208C). All sounds are made with the 208C. Drumcomputer is the Boss DR-220A.
Very special thanks to Emiel for lending me his Buchla 208C."
"Buchla 208c Easel Command. It is equips with the usb hub and midi. Comes with the Portabellabz 3 card hub, an Ems VSC3 oscillator card and the Portabellabz Stoned Marten card!"
"Here is 'Luna part III'. I'm using a Buchla Easel Command 208C, Monome Norns Shield with the 'oooooo' script loaded and a Chase Bliss Mood mkII pedal. It was recorded on tape with an Uher 4200 Report Stereo IC."
"I upgraded the knobs to the retro style Rogan knobs. I will also include the original knobs. The midi host module is also installed. Five additional shorting bars and rack ears also included.
See my other listing for the LEM218 v3 keyboard." Listed here. Pics captured below.
"Hand-Built Buchla Easel by Constantin (Portabellabz)
This setup was meticulously hand-built by Constantin at Portabellabz, with all components in perfect working order.
Price: $8,000 USD (equal to my original investment). I’m open to reasonable offers. Location: Portland, OR. Local transactions are preferred, but I’m willing to ship if necessary.
Feel free to ask any questions—I’ll do my best to provide detailed answers.

Portabellabz ToolBox: Includes slew limiter Roland Klinkenberg Sequencer Aux Expander: Includes Mod Expander Custom Hard Case: Custom made by Road Cases USA Rare SAmodular Keyboard and Case
The 218 keyboard and case are from SAmodular, with specific modifications by Constantin to ensure peak functionality. Note that the keyboard is no longer in production, making this setup particularly unique and valuable.
This is a beautifully customized Buchla Easel, built and modified by one of the most respected names in the field. Don't miss this opportunity to own a one-of-a-kind instrument."
"Buchla engineer-designer Joel Davel sheds some light on the 208's card slot and how it figures into the general operation of the 208 or 208C. This informal but fairly comprehensive video explains how the card slot works and how it reveals the how the 208 control works in general."
"This is 'Luna part II'. I'm performing with my Buchla Easel Command 208C, Strymon Volante and Strymon Nightsky. The audio is sampled continuously on the Elektron Octatrack in two alternating recording buffers. The third track is trigging the samples and adds various effects. The final piece was recorded onto a compact cassette.
The moon was recorded with a Panasonic DC-G9 with a Leica DG Vario Elmarit 100-400mm lens mounted on an Olympus telekonverter MC-20 (2X zoom)."
"Sat with this one quite a bit for quite a bit.... kept it unlisted for over a year but after some revisits thought maybe its time to put it out there. Still stand by what I initially thought, its a "Curate's egg... Good in parts". Squarp and Coco were still newish at the time of this jam so still finding the feels.
This is what I thought of it back then:
I got a new brain!
Here's a full 45 minute noodle with the incredible Squarp Hapax front and centre. To say this is the most powerful hardware sequencer I have ever got my hands on is a total understatement.
WARNING This pretty experimental jam is not for the faint hearted in certain sections. Focussing on Hapax and the CocoQuantus it gets noisy and out there but that's what I love these days.
It was improvised and live-sequenced over a couple of initially formed sequences. There are good bits but also some really bad sections in the middle too. I considered cutting these out but that would be a hard edit and they eventually do settle down. I'd say the worst bits are: 20:30 - 21:26 (shitty idea to try and record a kick bass line without tuning the kick!) 28:39 - 29:42 (combo of not realising that the 1010 Blue box was turned down and having a few moments of forgetting how the CocoQuantus worked... oh and a pesky Buchla sequence I forgot to stop!)
Hapax is firing off and controlling a ton of stuff in the room: Circuit Rhythm Ciat Lonbarde CocoQuantus (clocking the loopers) Nord Drum 3p Rossum Electro Assimil8or (through CV.OCD) Meng Qi Wingie 2 Novation Summit - also acting as a controller keyboard for everything in the set-up Buchla 208C Norns (running Plonky Script for multisamples) Just Friends in polysynth mode Vongon Polyphrase Vongon Ultrasheer Mutable Instruments Beads and some dodgy singing All connected via Hapax's MIDI Outs and a Conductive Labs MRCC"
