"Original vintage Prophet 10 with Wine Contry MIDI and Analogue Renaissance REV-1 downgrade installed in the lower board. With this 'downgrade' the CEM3320 VCFs in one of the two 5 voices board are replaced with the new SSM2040 VCF clones, like in the Rev 1 & 2 Prophet 5. This way you have both Rev 1/2 and Rev 3 filters in the same vintage synth. REV -1 downgrade also adds two new features not present in the original Rev 1/2:
- variable Q-compensation that restores the loss of bass when resonance is increased (14dB is lost at the onset of self-oscillation in the original filter design).
- the option to use the REV -1 as 2-pole filter instead of the original 4-pole configuration. Most non-linear effects happen in the first two filter stages, and the 2-pole mode lets you hear these effects unfiltered by the last two stages."

A live synthesizer jam performed entirely on hardware, with the Fourm at the centre.
The amazing Devin Belanger (@devinbelangermusic) aka Miles Away (@thisismilesaway) was kind enough to lend me his Sequential Fourm. Thank you, Devin! If you haven't checked out Devin's amazing channel or his music, please do so!
The Fourm is Sequential's entry-level analog polysynth, as far as I can tell. It has four voices, which is somewhat limited but OK for many circumstances, and sounds (to my ears) as good or better than any other Sequential synth I've personally owned. (Note: I haven't had a Prophet 5/10 and Devin swears by that thing.) So if the sound and a decent workflow are all that matters for you, and four voices is enough, then this thing is a no-brainer.
That said, its main feature is its poly-aftertouch keybed, which allows for you to modulate sounds by pressing into each of the keys. I love polyAT, and the Hydrasynth's polyAT keybed was tremendously inspiring to me. That said, I really struggled to get the polyAT to feel right for my playing. The biggest issue was a discrepancy between how the black keys responded versus the white keys. For the white keys, I could get a great linear aftertouch response, but with the black keys, it would often quickly ramp from 0 to 100 in a way I couldn't control. This could be something I get better at, or maybe it's this particular unit, or maybe it's just an issue with my skills. But ultimately, I found that the polyAT wasn't for me.
The sound, however, most certainly was. This thing sounds amazing. Here, I ran it through the Walrus M1 Mk2 (for auto-panning) and the Empress Reverb (for reverb), and then into the Soma Cosmos for looping. The first half was the more traditional "song" aspect, but truthfully, the second half wandering was my favourite. I could listen to a synth like this all day.
Thanks for listening.

2. GForce Prophet 5 vs the Hardware - Starsky Carr
I put the GForce Prophet 5 VST head-to-head against my real Sequential Prophet 5 hardware — testing filters, oscillators, envelopes, LFOs, vintage mode, FM, sync, unison, and more — to find out just how close it really gets.
The GForce Prophet 5 is the ONLY Prophet 5 software officially endorsed by Sequential, making it the only plugin that can legally call itself the Prophet 5. But does the endorsement mean anything sonically? After hours of clinical testing with spectrum analysis, oscilloscopes, and direct A/B comparisons, the results genuinely surprised me.
In this video:
Rev 1 vs Rev 2 vs Rev 3 filter comparison (SSI vs CEM — hear the -difference)
Oscillator shapes: sawtooth, square, triangle side-by-side
Pulse width modulation & LFO speed accuracy
FM / oscillator sync behaviour (I did find a minor difference here)
Polymod and audio-rate filter modulation
Unison & Vintage mode — does the voice-to-voice character match?
Low frequency oscillator mode
X-Mod section: LFOs and envelopes on everything
Built-in effects: chorus, phaser, distortion, multi-mode filter, delay, reverb
CPU load test: 10 simultaneous instances vs Ozone on the master bus
The verdict? The differences I found are no greater than you'd hear between two hardware Prophet 5s. If you don't own the hardware and aren't doing a clinical A/B, you will not notice them.
The GForce Prophet 5 is also remarkably CPU efficient — 10 instances use less CPU than a single Ozone instance. It adds two layers, up to 10-voice polyphony, full CC modulation, and an X-Mod section that turns a classic polysynth into something far more powerful."

Video descpription in Googlish:
Instead of a traditional review of the Sequential Fourm, we decided to take a different approach: putting it to work on a specific track. And not just any track: "Fade to Grey" by Visage—an absolute classic of 1980s British synth-pop. Every melodic and accompanying track you’re about to hear was created exclusively using the Fourm, starting from factory sounds (drawn from the approximately 300 initial presets) with only minimal tweaks. The only element not provided by the synth is the drums: an AI-generated Roland CR-78-style pattern, occasionally reinforced with a kick and snare from Logic’s sound library.
Along the way, Pablo demonstrates how to truly harness the power of a modern polyphonic analog synthesizer: polyphonic aftertouch (key for the lead vocal line, where some notes come alive while others fade out completely), intense mixer feedback (ranging from subtle thickening to nonlinear behavior with "ghost" harmonics), audio-rate filter modulation from Oscillator 2 (adding anything from brightness and vocal-like character to total sonic breakdown, depending on the intensity), glide for creating transition sweeps, and the LFO in random mode feeding the filter to ensure every note sounds unique.
We also cover specific recording techniques: layering basslines via MIDI using two different sounds and panning them; doubling hand-played pads so that the two takes aren't identical; and recording a MIDI pattern to free up both hands, allowing you to perform real-time timbral tweaks—adjusting the filter, resonance, and modulation intensity—during the actual audio recording.
๐ A quick refresher on the Fourm: a compact 4-voice analog synthesizer featuring two VCOs per voice, a 4-pole low-pass filter derived from the Prophet-5, one global LFO, two ADSR envelopes, a mixer with feedback capabilities, no internal effects, a mono output, a 37-key "slim" Tactive keyboard with polyphonic aftertouch, and a modulation matrix—inherited from the Pro-1—that is directly accessible right on the front panel. 00:00 Original vs. Fourm Version 00:24 Intro 01:35 Fourm Features 03:34 Polyphonic Aftertouch 04:57 "Fade to Grey" Intro 07:07 Bass 08:34 Chords 10:17 Sweep 12:32 Melody 18:50 "Clavi" Sound 19:34 Drums 20:39 Full "Fade to Grey" Version
"A good ol' filter demo like it's 2008, except it's '26! Thonk's Double Bubble is a stereo Prophet 5-style "2040" DIY-kit filter (and VCO!) with crossmod and feedback capabilities that can make it go from classic to nuts.
Thonk hired me to demo this module in a video. Thanks Thonk! This thing really is a beaut (and their VCO is really good, myself and Divkid were playing with one the other day and it tracked the best part of 10 octaves)."

"Sound bank notes
In my opinion, the Murmux Adept is a modern classic among synthesizers. It oozes quality and depth with a vintage analog sound and a strong personality. The oscillators, filters and analog stereo bucket brigade delay (BBD) interact to create a rich palette of timbres, with an inclination towards dark ambient textures.
It excels at ambient pads, textures and atmospheres so I have exploited this in many of my patches. I have also created more conventional sounds such as strings and brass which sing with power and majesty – rivalling those of the Sequential Prophet 5. Lead sounds are another strength of the Murmux, so you will find many within the bank ranging from pure triangles and sines through to aggressive and expressive saws.
Although the Murmux looks like a very simple synth - lacking complex features like a modulation matrix, in fact it is possible to create many layers of modulation simultaneously. You can for instance, assign velocity (how hard you press the keys) to modulate envelope times while also morphing between waveforms in both oscillators and using aftertouch to control filter cutoff and resonance. In this sound bank I have used modulation comprehensively and all patches have parameters assigned to the mod wheel as well as aftertouch and/ or velocity to maximise the expressiveness of the sounds.
The delay is a big feature of this synth so I have used it a lot, although you will also find traditional analog synth patches with no effects at all. The BBD resonator and ensemble modes are powerful, yet I have tended to use them for subtle modulation to thicken sounds or to create gentle flanging.

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!

"This collection of vintage synthesizers has grown with me for years. Most all of these instruments have been used on many projects, including VeggieTales, a variety of remixes, and many PlayStation video games and marketing and promotional discs. Most recently they were used on the Mass Effect Andromeda video games soundtrack. They have also been sampled and are part of the SoundVault Collection and the Kurzweil Analog Collection for the K2000 series samplers. VEMIA note: to forestall many inquiries, The seller’s idea is that he wants to sell it as a whole. That may or may not work out in this auction. If it doesn’t, obviously he’ll be free to do whatever he wants after the auction finishes.
It all works. Everything has been kept in a clean, smoke-free, climate-controlled studio. I have always fixed things myself, so everything is operational and sounding great. I have repair notes on the synths that received attention, though most of them have worked great over the years, without much need for repairs. There are also several MIDI to CV converters so they can all be controlled by computer, plus cables if desired. And a few have cases and manuals.

"Creamware pro-12 asb hardware synth desktop in very good condition. these are of course the analog modeling emulation of the classic prophet 5 and pretty overlooked. its sounds absolutely amazing and a bit of a surprise it comes way closer to the prophet 5 than any other synth at the fraction of the price. i would say 75 percent pure prophet 5 and 25 percent va . this example is in very good condition and comes with a brandnew powersupply . it has only very few marks for its age check pics i have the original box but its very old so im still gonna put yet another box arround it to sending they can be a bit buggy but this one plays very nice nothing i noticed also smooth encoders and no stepping atall in case someone wants to upgrade the firmware i can supply the all important unit code relating to the serial number . its essentail for the upgrade . though i was told this unit propably has the latest firmware anyway as the last one was released in 2016 . reason for sale i got a prophet 10 dekstop at 5 times the price of this lol synth can be picked up in south london or brighton or send insured thanks"
A lot of people think it's just about voice count, but there's more to it. I'll take you deep into their unique character, how their polyphony impacts your composition, and critically, which one truly fits your specific production workflow and musical vision. In this video, I'm putting these iconic synths head-to-head ๐️. I'll compare their oscillators (sawtooth and square wave) and filters (Rev 1 and Rev 3) to uncover all the sonic nuances. I'll also explore modern features like aftertouch and velocity modulation found on the Prophet-10 ๐น, showing you exactly how they impact expressive performance. You'll hear direct comparisons, and I'll show you how these analog machines handle tuning and drift, giving you my comprehensive take on what makes each Prophet unique.

"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."
