The Sh*t Synth - Walkthrough video upload by CROW HILL XTRAS

Press release follows:


The Crow Hill Company turns to extensive and rare collection to turn out THE SH*T SYNTH as compendium of 48 circuit-, wave- and sample-bent instruments

EDINBURGH, UK: The Crow Hill Company is proud to turn to its own extensive and rare collection of hardware to turn out THE SH*T SYNTH — available as a compendium of 48 circuit-, wave- and sample-bent instruments inspired by some of the Edinburgh-based enterprise’s eclectic musical favourites (spanning the likes of Aphex Twin, Boards Of Canada, Joe Maus, Jon Brion, Laurie Spiegel, Radiohead, Throbbing Gristle, and Yazoo) to create something that they collectively ask: is it just shit or ‘the shit’? — as of April 7…

Whatever way anyone chooses to read into the titling of THE SH*T SYNTH as the latest entry into The Crow Hill’s ongoing ORIGINS series of sample-based virtual instrument plug-ins, one thing is for sure: it readily represents a broad selection of three categories of 16 workhorse instruments each, effectively wrapped up into a single plug-in designed to bring a cohesive approach to making music more edgy, lo-fi, retro, and — swimming against the technological tide of so-called progress — decidedly AI (Artificial Intelligence) slop-free. From pianos to strings, plucks, beeps, bass, and pads, the compendium that is THE SH*T SYNTH has been lovingly sculpted by the Edinburgh-based enterprise’s media composer and ‘samplist-in-residence’ Christian Henson to take the hassle out of making existing sounds less refined, catering to those looking for an entirely new bank of Mellotron-style sounds as well as synths that have been long forgotten — for good reason, too!

"Extremely rare outside Japan - apparently Moridaira / Denki Sangyo, the firm SCI employed to make the Six-Trak, decided to make a few changes to that design and re-market it as the Pro-8 in Japan. Five octaves instead of four, eight voices instead of six, and split instead of multi-timbral. SCI then eventually made a couple more changes, and introduced it as the Split-8 in the rest of the world.

This, like all Pro-8s, started out as 100V Japanese power, but has been converted to 240V.

Lots of little points of interest: for instance, this one has a Denki maker label but also a Sequential Circuits one. They both call it Model 608, and SCI have a serial number:02033. 608 presumably because the design was changed from six to eight voices?

It's not a Prophet-5 for sure.... but if you like the Six-Trak sound you'll like this a lot. And it's rare as anything :) Plus it's probably the only synth in the world to have a scribble-strip matrix for entering your program sound names. The matrix looks unused.

Sequential FOURM vs Prophet 5

video upload by Starsky Carr

"Is the Sequential FOURM effectively a "Prophet 4"? In this deep-dive comparison, I put Sequential’s compact powerhouse up against the legendary Prophet 5 to see how closely it recreates that iconic vintage DNA.

While the FORUM shares a strikingly intuitive Prophet-style interface—complete with dual oscillators, a resonant low-pass filter, and a dedicated polymod section—it also brings modern innovations to the table that the original Prophet simply can’t match.

We’ll explore the sonic character of the FORUM’s SSI chips, which act as modern recreations of the warm, fuzzy SSM chips found in the original Prophet 5 Rev 1 and Rev 2. By recreating classic factory patches side-by-side, we reveal the subtle differences in envelope behavior and modulation flexibility between these two analog beasts.

🎹 What’s Covered:
• The "Prophet 4" Factor: Comparing the interface, layout, and "familiar" feel of both synths.
• SSI vs. SSM vs. Curtis: Breaking down the filter and oscillator chips that define their warmth and grit.
• Modern Upgrades: Exploring the FORUM’s Poly Aftertouch, built-in arpeggiator, and digital clock sync.
• The Feedback Circuit: A demo of the FORUM's unique feedback loop that adds "MiniMoog-style" grit and prevents bass loss at high resonance—something the Prophet 5 famously struggles with.
• Patch Recreation: A side-by-side listening test of 8 classic patches to hear the real-world sonic differences.

"Great and powerfull analog synth from 70's This one is in excellent cosmetic conditions (I am the 2nd owner and always kept in free-smoked studio as the 1st owner too) the Pro-One can generate many of the same sounds as the Prophet-5 and Prophet-10, capable of supremely punchy bass lines and distinctly ripping leads, fueled by two VCOs, referred to as Oscillator A and Oscillator B. he Pro-One has extensive modulation provision with three modulation sources available, featuring Filter Envelope Generator, Oscillator B, and a separate LFO. Each can be mixed and routed for either Direct or Wheel-controlled modulation. On the back of the unit, there are Audio, Filter CV, Gate/CLK, and CV inputs. Other features include a 40-note sequencer, an arpeggiator, Pitch and Mod wheels, Repeat and Drone switch, Single and Multiple-triggering keyboard modes, and the unique Automatic Glide, enabling one-handed complex, 'tuned' pitch bending sounds."

"RetroSound Studio Tour
Classic Analog Polyphonic Synthesizers from the 1970s and 1980s

In this episode of RetroSound Studio Tour, I explore the sound, design, and history of legendary analog polyphonic synthesizers from the golden era of electronic music. These vintage poly synths defined the lush pads, warm brass sounds, and cinematic textures heard in synth-pop, progressive rock, disco, film scores, and early electronic music.

This studio tour focuses on true analog polyphonic instruments featuring multiple voices, voltage-controlled oscillators , classic analog filters , and rich modulation systems. Unlike monophonic synths, polyphonic synthesizers allow full chords and layered harmonic textures — making them essential in 1970s and 1980s music production.

"KOSMOS – A Compact Generative Sequencer Driving the Prophet‑5

This short clip features KOSMOS, my standalone generative MIDI sequencer, controlling a Sequential Prophet‑5. KOSMOS creates evolving melodic patterns and rhythmic variations in real time, while the Prophet‑5 provides its unmistakable analog warmth and depth.

The performance is completely autonomous — no DAW, no external processing — just KOSMOS generating the sequence and the Prophet‑5 responding with its classic tone.
It’s a small glimpse into how KOSMOS interacts with hardware synths and how expressive the pairing can be."

Dreamt in Passing | Sequential Take 5 (Dreamscape)

video upload by hvegel

"A patch I created to showcase how massive the Take 5 can get. Apart from a bit of 'ITB Mastering' this is just the instrument. With 'Vintage knob' or things like LFO slew, not engaged, yes, it is true, this instrument, by design can do some very precise Analogue material, think Elektron Analog 4, but it can get into the weeds, and sound out right wild, and unruly, not unlike the Sequential Godfather it shares its DNA from.

The latest firmware update, has really encouraged me to start using this more as centrepiece in my studio. A/B-ing, sound for sound with the Prophet 5 Rev 4, with a bit of attention to detail with programming, it gets just about every bit there (factoring in a substancial lower mid-range bump in tone with P5, with a touch of those mids being abscent on design, some may consider the Take 5 a bit more 'glossy'), The Prophet 6 might be a better (more immediately satisfying) than both the P5 ot T5, but Sequential has done a wonderful job at taking the core Prophet sound, its Rev 1/2 filter, modernising it with bass compensation, and stable filters, that can be pitched to a wonderfully pleasing instability.

This reads a bit as an apologist letter, but I also think the Take 5, is very misunderstood amongst the Internet, for what it's DNA really is, how these firmware updates keep unleashing it further into the stratosphere, and despite its massive popularity at your local Synth Store, it's still this mystified object that kind of gets relegated to a vastly updated Dave Smith Mopho."

Comparing the Sequential Fourm to the Pro-One

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."
