SCI Pro-8 rare 8voice Split MIDI Analog Synth SN 02033

"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.

Packing 18GBP."

Sequential Circuits Six-Trak song Pure VCO Analog 27.3.2026.

video upload by Veli-Matti Rautio

"Got new Eprom V14 to Six-Trak and changed it. Next was testing the synth's working and here is that test session. Arp & latch sound nr. 14, lead & bass sound 01. No additional effects used, only Six-Trak's pure single VCO analog sound. Sony FDR-AX43A video kamera. Composed, played live, arranged and improvised by me in Studio Tupos 27.3.2026. Nr. 1544.
Tilasin Ebay:stä Six-Trakiin uuden V14 Epromin. Vaihdoin sen paikalleen ja pitihän sitä testata, että toimiiko enää? En toki saanut Six-Trakin sekkaria synkkaamaan RX21 rumpalin ohjaukseen, mutta sentään soitto onnistui :) Arp & latch soundi nr. 14, soolo ja basso nr. 01. Sony FDR-AX43A kuvaajana."

SEQUENTIAL TRIGON-6 POLYPHONIC ANALOGUE SYNTH (DESKTOP)

"We say...
A pre-owned Sequential Trigon-6 in very good condition. It comes with original packaging and power cable

Manufacturer's description
Experience the Power of Three Oscillators and a Ladder Filter with the Trigon-6 Module

The Sequential Trigon-6 desktop module delivers the same massive sound and hands-on sonic control as the Trigon-6 Keyboard. It features the same pure analog signal path with discrete oscillators and filters, and the same high-quality digital effects. It also has the same intuitive layout with full-sized knobs and switches that make it quick and easy to shape new sounds.

The Trigon-6 module sounds huge — just like the keyboard, because it is the same six voice polyphonic instrument, just in a smaller form factor. And if you want even more polyphony, you can use the poly chain feature to link any two Trigon-6s for a stunning twelve-voice synth!

A Sound That is Bold and Familiar

The Trigon-6 is Sequential’s polyphonic take on the classic, thick and creamy, 3-oscillator-plus-ladder-filter analog sound that defined the dawn of the synth era. It’s a sound that bridges genres and styles — now refined and redefined with Sequential’s own modern imprint.

As with the OB-6 Keyboard, all parameters are at your fingertips, with full-sized knobs and switches and a comfortable, intuitive layout.

How does it sound? Massive — just like the keyboard, because on the inside, it’s exactly the same. The same analog signal path with discrete VCOs and VCFs. The same high-quality digital effects. The same classic Oberheim sound that has been earning raves from musicians around the world.

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.

Prophet-5 vs Prophet-10: The sound test & my REAL thoughts

video upload by Doctor Mix

"🔥🎹👉 Explore the Sequential Prophet-10: https://sequential.com/product/prophe... 👈🎶🔥

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 🎛️. 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 🎹, 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.

🎬 What you’ll see and hear in this video:

• 🔊 My in-depth comparison of Prophet-5 vs. Prophet-10 oscillators
• 🎛️ Dissecting the sonic characteristics of Rev 1 and Rev 3 filters
• 🎵 The impact of aftertouch and velocity modulation on synthesis
• 🧐 Exploring analog drift and the 'tune' function
• 🎹 How polyphony (5 vs. 10 voices) shapes my playing
• ✨ Uncovering subtle sonic differences in sawtooth and square waves
• 💡 My practical insights for choosing the right Prophet for your studio
