Sequential Fourm Review

video upload by Molten Music Technology

"Does this compact 4-voice analogue synth have what it takes to be a serious synth? The Fourm is neat, capable, sounds like a Sequential synth and has an elegant simplicity that really appeals to me."

"The Sequential Fourm is the brand's first 100% analog synthesizer, featuring the Prophet-5 filter, an intuitive modulation matrix derived from the Pro-One, and polyphonic aftertouch. Oh, and yes, all this for under €1000! François shows you everything you need to know about this synthesizer, its architecture, and its distinctive character!"

Sequential Fourm - Great for ambient music.

"Patches will be available at https://www.orano.co.uk/shop or http://www.synthsounds.co.uk

All sounds with exception of drums are from my forthcoming Sequential Fourm Bank "Quatrain Volume 1"

This synth can cover so much ground, from fat bass to delicate bell like tones. it's remarkable what ‪@SequentialLLC‬ have a achieved with this.

enjoy
Scott."

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."

How to Start Tracks: Fourm + Microcosm into Digitakt 2

video upload by Sineway

"Fourm into Microcosm into Digitakt II – how I built a beat from nothing, faster than I expected.

In this video I build a beat from scratch using a brand-new setup: Sequential Fourm into Hologram Microcosm, captured and shaped on the Digitakt II.

Instead of treating effects as something you add at the end, I’m using the Microcosm as an idea generator - letting it transform a simple init patch into something that suggests harmony, rhythm, and direction very early on.

This is the first time I’ve made a track with this exact setup, and I was honestly surprised by how quickly it led to usable musical ideas.

The goal here isn’t to finish a track. It’s to show how I like to start - how I go from nothing to a beat that feels worth exploring further.

If you’ve ever felt stuck looping the same pattern without knowing where to take it next, this video sets up the foundation for what comes after. I’ll continue from this exact loop in the next video, where I focus on breaking out of the single-loop deadlock and opening things up into multiple patterns and directions."

The Sequential Fourm: He didn’t get it… until he played it.

video upload by Devin Belanger

"The Sequential Fourm looked limited on paper, but after a month in the studio, my perspective has completely shifted. In this Fourm review & demo, I’m moving past the specs to focus on 4 performance demo songs that showcase the unique tactile experience of this 4-voice analog synthesizer.

The combination of a 100% analog signal path and Polyphonic Aftertouch makes this one of the most expressive instruments Sequential has released in years. Whether you are scoring for film or sound designing from scratch, the Fourm demands a different approach to synthesis.

Today Marks the 10th Anniversary of the Sequential Oberheim OB-6

Andrew McGowan, pictured here with Tom Oberheim, wrote in to let us know today is the 10th Anniversary of the Sequential OB-6. Andrew was a product designer at DSI/Sequential and worked with Tom Oberheim on the OB-6.

You can find a write-up on some the development of the OB-6 as well as the Prophet-6 on his website, https://www.smartbombdesign.com.

A couple of excerpts:

"I was sitting in my office at Seer Systems one day in 1997 or thereabouts when the phone on my desk rang. It was Dave Smith calling from his home. 'I’ve been talking to Tom Oberheim. He’s between jobs and wants to learn about software synths, so I asked him if he wanted to write the Reality operation manual. Can you get him set up and manage that?' I knew who Tom was, of course, but I had never met him, and now Dave was asking me to be his manager. I had no reason to believe that Tom was anything other than the warm, bright, and kind person that I now know he is, but the idea that I would be managing him made me deeply uncomfortable.

Seer Systems was in the process of developing Reality, which is generally considered to be the first 'professional' software synthesizer, though I’m not certain what makes one synthesizer professional and another not."

[Side note: Propellerheads Rebirth was also released in 1997, however the demo version was released in October 1996. A bit like The Damned vs. Sex Pistols for those in the know!]

And [thought this was funny]:

"Those Fucking Lines

Tom and I had talked about synths over the years and, on several occasions, he remarked how often people asked him to remake the OB-X, perhaps because not many were made. Or maybe Rush/Tom Sawyer? I don’t know. What little I did know about the OB-X was that it had a (low-pass only) SEM filter, and we had already made a synth with an SEM filter in it. And our hardware engineer Tony Karavidas had worked at Oberheim and owned multiple Oberheim synths. I also felt very strongly that if we were going to make two poly synths that were essentially the same except for the filter, the 2-pole, SEM state-variable filter would be complementary to the Prophet-6’s 4-pole, OTA low-pass filter.

Tom’s wish list was short. He didn’t want the Prophet-6’s analog distortion. And he wanted the OB-Xa’s blue lines."

Read the rest here

[P.S. I still own an OB-6 desktop and it's one of my most cherished synths. There is something organic about it. The demos I've heard of Sequential's new FOURM have that about them. I have enough synths as it is but the FOURM is very, very tempting for this particular reason.]
