The MASSSIVE caladan update you've been waiting for....

video upload by Isla Electronics

"It’s rough as hell, I apologize in advance, if you have a bit over an hour to spare and want to see almost everything the machine does now.. then be my guest and come and watch the youtube video.I’m uploading it as a youtube premier now so I can sit there for a bit with y’all and we can watch it together and you can ask me any questions you like while it’s playing…I go over how the machine works, every engine the machine has and just about everything I can think of.. it’s finally an actual working synth, it sounds great (although my video quality leaves a lot to be desired)This is an update, not a commercial, The machine is solid, I am not…"

Comparing the Sequential Fourm to the Pro-One

"I Compared the Sequential Fourm to My Pro-One" video upload by Starsky Carr

0:00 intro jam and info
5:04 Really Deep Bass - THE FILTER
9:14 They've got Oscillators
11:24 Creating a Few Tones
15:11 PWM and how to match them
19:10 F to the M
20:00 Show Me The Sync
21:19 Pushing the Envelope 24:06 Overall..?

"Some genuine surprises in this head-to-head with the Sequential Fourm and the legendary Sequential Pro-One to find out if the Fourm can give the same vibe.

At first glance, the architecture looks familiar: dual oscillators, classic envelopes, a focused modulation section, and unmistakable Prophet-era DNA from Prophet-5 territory. But the big question is this: does the Fourm capture the raw punch, deep bass, and aggressive character that made the Pro-One a cult classic?

.. and I know it's not a clone :) but in this in-depth demo and comparison, I explore:

Oscillator behaviour, sync, PWM and FM
Filter differences (including low-end depth and resonance extremes)
Envelope response and modulation range
Bass performance, subs, and room-shaking tones
Where the Fourm goes beyond the Pro-One — and where it doesn’t

Rather than obsessing over perfect null tests, this video focuses on feel, playability, and whether the Four inspires the same kinds of sounds and musical ideas as the original Pro-One.

If you’re into analog monosynths, Sequential gear, vintage vs modern comparisons, or you’re wondering whether a contemporary synth can truly stand in for a rising-price classic, this one’s for you.

🎧 Headphones or proper speakers strongly recommended — some of these bass tones go very deep."

Sequential Prophet 5 - a vintage Hero! Sounds only! No talking

"Prophet 5 Analogsynthesizer from the early 80's. One of the best Synthesizers ever made.

Sounds only! No talking.

He Hates This Synth Because…

video upload by Anthony Marinelli Music

"In this video, I pick one thing I think I hate about 12 classic synthesizers—and then follow that feeling wherever it leads.
We’re talking about legendary instruments:
Minimoog, MS-20, Prophet-5, Jupiter-8, ARP 2600, Moog IIIc ('Plantasia'), Oberheim 4-Voice, Oberheim OB-X, Synclavier III, Elka Synthex, and Yamaha CS-30.
What starts as frustration with a workflow choice, a knob, or a design limitation slowly turns into something else entirely.
Along the way, I realize this video isn’t really about hating synths at all. It’s about relationships.
Every one of these instruments has limitations—and so do we. In any good relationship, not everything is perfect. But when you stop fighting what something isn’t and start understanding what it is, those limitations can become the very thing that leads you somewhere creative and unexpected.
Instead of endless options, boundaries create focus.
Instead of frustration, they create identity.
And in learning to understand these instruments more deeply, I ended up learning something about myself.
This is a video about synthesizers—but it’s also a small morality tale about creativity, acceptance, and finding freedom inside constraints.
Let me know in the comments:
Which synth do you love… even though it drives you crazy? 🎛️"

GERMANIUM FEEDBACK // SND FB-14 MK2 Filterbank // The CRYING GAME // No Talking

video upload by LESINDES

"The SND FB-14 is a stunning GERMANIUM TRANSISTOR based FILTERBANK with 14 fixed Q band pass filters. As you can hear in the demo the sound shaping shaping potential of this filter is enormus.
SND FB-14 is assisted by WLK-Audio Inductive Filterbank (silicon) to control excessive boosts and the core of the wiring: ART passive splitter + mixer SplitMix4. The SplitMix knob marked with the WHITE DOT (blue, unused in this session, is for additional feedback!) is controlling the signal that is fed back into SND.
The basic feed is from TORSO Electronics S-4 sculpting sampler."

Building the ReZyklus - Vangelis' Zyklus MPS1 Clone

This one is in via Jeroen of https://zyklus-mps.com/

"A while ago a group of enthausiasts set out to create a clone of the Zyklus MPS-1 that was made famous by Vangelis for its use on Direct (this was also the inspiration for the actual 'Direct' system he used until ca 1994). The original creators of this machine, Pete Kellock and Bill Marshall graciously allowed us to use the schematics and software to create this clone and have given us their permission to set it free for everyone who wants to make their own. So here goes:

In this GIT repo is everything you need to create your own machine. You will have to source your own parts, but there is a list for that. The parts are basic components, nothing custom, but some items may become slightly rare (like small EPROMs).

Its basically just a Z80 based computer.
There are also files to have the circuit boards and panels created (we used jlcpcb for that), and some 3d printing files for various panel work. A lot of the buttons etc you can get cheaply from Aliexpress and the like. Bin files for the EPROMs are also avialable. I've been also given permission to open source the actual source code, and I will do that too, at some point, but I'm still working on a few small issues before I can do that.

https://github.com/jeroenhn/zykl

There is a discord server you can join where you can chat with other builders.

The clone as we made it, is a dedicated to the memory of Vangelis and it's noted as such on the main circuit board."

See this previous post for a Demo tape on the original Zyklus. See the Zyklus label at the bottom of this post for additional posts including a documentary with Vangelis.

Building a Minimoog Model D From Parts

video upload by synthpro

"Hey Guys,

In this video, I bring you along the adventure of building a really nice Minimoog from parts I have had over the years.

Michael heard this unit on a little Instagram post I made when I first started testing to see if I could get a working unit from the parts and immediately sent me a down payment. It took me about 2 years to source everything needed but Minimoog SN: 5250 now lives a healthy life once more.

Thanks for watching!

Sincerely,
Jareth"

"Our West Coast Whirlwind!

Still feeling the synthesizer love from last month’s California visit to NAMM / Buchla & Friends!

At NAMM:

Anthony Marinelli visited our booth
The Blue Meanie was at our booth for a whole day!

ARP 2600: Drew Schlesinger demonstrated patches using the 2600 software included in the Korg Collection VST 6. 2 Lucky folks won a signed CD and poster from Martin Gore

And Congratulations to Violet Burns who won the Korg Collection 6!

Then it was off to Buchla & Friends – January’s biggest two-day collection of hands-on synths on the West Coast!

Remember: The Most Creative Part of an ARP synthesizer is You!

NAMM 2026 would not have been possible without the help of the following people and companies:

Thank you to Korg, Inc for the Korg Collection Giveaway and helping us make NAMM possible.

Thank you to Sean Weizmann of Arturia for the midi controller

Thank you to Beyer Dynamics for the headphones

Thank you to Ryan Hawkins of Hawkins Restorations for use of his Blue Meanie, Tonus 2600, OMNI and Odyssey, and for being the best Booth volunteer along with his assistant Miles.

Thank you to Julie Lewis for volunteering at the booth and for her donation last year of a rare ARP Soloist that was owned and played wonderful late husband synth legend Don Lewis.

Thank you to our Board Member and booth volunteer Stephen DeJesus for selfless assistance at both NAMM and Buchla & Friends.

Thank you also to Chris Cardone, Joe Castronovo, Tom Cusimano, Deanna DelVino, Rich Formidoni, Martin Gore, Andy Joyce, Brian Kehew, Ruperto Ifil, Mary Lock, Anthony Marinelli, Mark Marshall, Mike Metlay, LaMar Mitchell, Tony Notron, Drew Schlesinger, James Terris and Brianna Tortino,
