"I've always loved 80s Sci-Fi soundtracks such as "Escape from New York" and 'The Terminator'. It's by no means a coincidence that they both share something in common; The Sequential Circuits Prophet 5. As the P5 is about as rare as a unicorn and as expensive as a decent car, I'll probably never get close to one. However, SCI's monophonic version of it, the Pro-One can still be found if you keep your eyes open. And sure enough, I managed to snag one.

So, here's an original track following the spirit of those great scores. Minimal and atmospheric, my take on a spot of Carpentry.

I've made a detailed walkthrough of the production and mixing of this track if that's of interest: [below]

Sounds used:

Sequential Circuits Nameplates Via Synthwood

You might remember Synthwood from previous posts. They specialize in custom wood cases for the Pro One and wood panels for various synths. They take custom orders and they now make nameplates for the Sequential Circuits Pro One, Prophet 5, and Sequential Circuits line of analog synths. You can find more images of the nameplates here. Title link takes you to Synthwood.

"We used a satin brushed stainless plate that is just a bit thicker than the originals. The result is it won't curly up or crimp as easily. I found this out by plopping down one a PRO-ONE and noticing it was slightly crooked, I was able to pull it off and re-set it without the folding. One other thing that is really noticeable is that the original PRO-ONE/SEQUENTIAL circuits (at least the rev1) isn't brushed, but a plain bright aluminum. I find the satin brushed aluminum to be closer to what the Prophet-5 has and much better looking.

We've also made our own little badge which we are shipping with our Pro-One, Prophet 5 and Mini-Moog cases. We don't install the badge, but we do write the completed date and a 3 digit serial number (do you think we could break 999?). Oh! And we *ARE* shipping all our wood Pro-One and Prophet-5 cases with the new nameplates.

We're asking $18 shipped for each nameplate (Add $3 if you're outside of the USA). They're currently listed on ebay, but we actually have a revamp, customer gallery and shopping cart in testing for our website that should show up next month."

Yazoo - ONLY YOU - Re-created w/ Sequential Circuits Pro-One Synth

Published on Jul 19, 2014 peahix

"Some friends needed the backing track of this song for their wedding, so I took the opportunity to geek out with it. The original is well-known by synth nerds as having been produced by Vince Clarke using only a Sequential Circuits Pro-One monophonic analog synthesizer. So, since I have a Pro-One, and there are scans of an old music magazine article online which show the settings for some of the sounds Vince used on this track (https://www.flickr.com/photos/8478882...), I figured I'd have a go at re-creating it.

First I transcribed the music (sequenced with Cubase), using soft-synth sounds as temporary stand-ins for the Pro-One. Then I had to dial in all the Pro-One sounds one-by-one and record each part via a Kenton MIDI-CV interface. I found that all of the patches from the article needed adjusting to get them in the ballpark, plus I had to create the other sounds from scratch (I've credited each patch accordingly). Having done so, I'm not convinced that every single sound on the original is actually a Pro-One. The "Tinkle" sound, for instance, sounds more bell-like on the original, so it could possibly have been something like a PPG. I don't think Vince had his Fairlight yet, otherwise I'd say it was that. Also, the string line toward the end of the song sounds like it might have been played on a polysynth, ie maybe the Jupiter 4 which Vince used alot at the time. Of course, there's also the snare, which was an 808.

In any event, I think I got pretty close with my rendition. Of course the effects and mix are going to be different, and some of the sounds are closer than others, but whatever.

If you want to give it a shot yourself, you can download the MIDI file and the patch sheets here (be sure to let me know if you make your own version, and give me a shout out if you post it online!): https://www.dropbox.com/s/lfn3vb1pxwq...

One tip: the cutoff of the "Wobble" sound varies a bit, getting slightly brighter during the chorus, etc. The only way to do this is manually while recording. I tried to use automation for this via the Pro-One's filter CV input, but doing so cancels out the Keyboard Amount setting, which is crucial for this sound, so I simply adjusted the knob in real-time.

If you liked this re-creation, check out my other videos for four "Speak & Spell" tracks that I re-created using only a Yamaha CS01-II synth.

Sequential Circuits Pro-One with Synthwood Case

Click here for shots via this auction.

"Sequential Circuits Pro One, serial number 6247. This is the superior and reliable J-wire keyboard model with the chassis mounted power supply. As the photos show, the control panel is immaculate. All knobs are original and just a couple have some slight fading of the white indicator line. As shown in the photos, there is some tape residue around the serial number sticker - mentioned for complete accuracy sake. Please be aware that there are some photos with camera flash wash-out/glare that just prove I'm a lousy photographer!

During the process of transplanting this into the new case, ALL rubber key bushings were replaced, so the keyboard plays like a dream. Additionally, all pots and switches were triple-flushed with Caig CaiLube MCL (Moving Contact Lubricant) 5% spray to fully clean all dust and old lube out. After that, every pot and switch was then lubed with Caig CaiLube MCL 100% spray to assure smooth, noise-free operation - and that they do!

The solid cherry case was made by Synthwood, who sells here on eBay, and includes the custom Dave Smith wheel box with clear pitch and mod wheels. Not only are the wheels nice and chunky, but the pitch wheel has spring return to center, which the originals did not have (they had a center detent). Not to disparage Synthwood in any way, but the beautiful finish you see here was done by me - I felt the synth deserved nothing less than a "furniture-like" finish. I painstakingly progressively sanded the case, ending at 400 grit, then hand applied a light cherry tinted Tung oil finish (two coats of color, one of clear). It turned out stunning, if I do say so myself. I also replaced the case screws with longer, proper wood screws for strength and aesthetics. The case alone, without MY beautiful finish job, will cost you $325.00 + $25.00 shipping, and a degree of custom fitting is required.

A custom made LeCover dust cover is included; the Pro One has ALWAYS been covered when not in use.

If you're looking at a Pro One of this caliber, you already know all the technical details of the synth itself, so I won't drone on with those. Suffice it to say, this Pro One is an amazing synth - sounds amazing, works perfectly and looks phenomenal. The investment I have in this in both time and money is staggering, any buyer will certainly get a bargain at any price. The cost to build one like this today, in materials alone, would be around $1,200.00 if you had to buy the donor Pro One as well."

Sequential Debuts the Pro 3 - Multi-Filter Mono Synth

Sequential Pro 3 INHALT Sound Design Demo Published on Jan 14, 2020 INHALTVIDEO

Update: some audio demos added below.

"Some time ago, I put together a video demonstrating the remarkable ability of the AS-1 synthesizer to mimic the classic Sequential Circuits Pro One. I sent the video to my friends at Sequential and expressed a great desire for a fully fledged, keyboard version of the synth. Flash forward to the tail end of 2019, and I’m sitting in front of the Sequential Pro 3. While the inspiration might have come from some aspects of the AS-1, the Pro 3 is so far and above, it truly deserves the title of FLAGSHIP.

To me, the central point of the Pro 3 isn’t necessarily the feature set, which is VAST, but the raw sound. This synth is a production workhorse that sounds proper. It has a kind of aggression, bigness, and elegance that is typically associated with some of the finest vintage synthesizers; the low end is massive and the top end can cut through but it’s that all important midrange that is the most impressive. That midrange synthesizer bass sound, that many other synths fail at (by over compensating lows and highs) isn’t an issue here and it’s that aspect that allows the Pro 3 to link the vintage to the modern. Simply put, any working producer looking for a flagship mono that can handle the rigor of modern production and can make as many classic vintage sounds as futuristic ones should not sleep on this.

The three filters on offer here all have their unique personalities and allow you to cover a vast array of sounds. The OB6 filter in particular is a favorite and combined with the sheer physicality of the analog vco’s used here, allowed me to get into a kind of Xpander territory. The ladder filter pounds and moves like a vintage synth. And the Prophet 6/AS1 filter is exactly what you expect.

No external sequencing or multitracking was used on this recording. Everything was made 100 percent on the Pro 3. This is a recording of all of the patches I submitted to Sequential for the Pro 3’s factory bank. A big thanks to the whole Sequential family and a massive congratulations from INHALT on this stunning new synth!"

Update: audio demos by Paul Dither:




And the press release: (side note: I believe this is the first solely Sequential branded synth after rebranding from DSI)

"Sequential Debuts Pro 3, Multi-filter Mono Synth Featuring VCOs, Wavetables

San Francisco, CA—January 14, 2020—Sequential today announced the Pro 3, a new flagship mono/paraphonic synthesizer. A hybrid instrument, the Pro 3 features three classic analog filters (Prophet-6, OB-6, and ladder) and three oscillators (two VCOs and one wavetable oscillator) along with a powerful new 16-track sequencer, and the ability to connect with modular synths through its four control voltage ins/outs.

“In many ways the Pro 3 is the evolution of a concept that started with the classic Sequential Circuits Pro-One,” said Sequential founder Dave Smith: “Pack as much power as possible into a compact footprint and make it sound awesome. To do that, we built on the strengths of its modern-day counterpart, the Pro 2, and created a worthy successor to both that sets a new benchmark for raw power and versatility.”

Part of this sonic versatility comes from the Pro 3’s oscillators: Two voltage controlled oscillators provide traditional triangle, saw, and pulse waves with waveshaping, while a third digital wavetable oscillator provides 32 tables of 16 waves each with wave morphing. Three vintage-style filters shape the sound of these oscillators. Filter 1 is a 4-pole low-pass design based on the Prophet-6 filter. Filter 2 is a classic transistor ladder filter with optional resonance compensation to preserve its low-end punch. Filter 3 is a classic 2-pole, state-variable design based on the OB-6 filter that can be continuously varied between low-pass, notch, and high-pass operation, with an optional band-pass mode. A Drive control provides additional punch to all three filters.

The feature set of the Pro 3 is rounded out with a multimode arpeggiator, three LFOs, four loopable ADSR+delay envelopes, dual digital effects (delays, reverbs, and various time-based effects), tuned feedback, analog distortion, and extensive modulation possibilities. The LFOs, delay, and arpeggiator can be synced to either the internal clock or an external MIDI clock. A programmable position-sensitive touch slider and pitch and mod wheels provide nuanced control over live performance. The synth is also capable of 3-voice paraphonic operation. This makes it possible to play 3-note chords where the three individual oscillators share a common filter and envelopes.

The full-featured sequencer provides 16-track sequences of up to 64 steps, with ratcheting, variable gate and sequence lengths, multiple playback modes, and paraphonic operation. It also syncs to MIDI clock and external audio input, and inputs/outputs control voltages. In addition to notes, sequence tracks can control any parameter in the 32-slot, 171-destination modulation matrix.

Another key feature of the Pro 3 is its four scalable rear-panel control voltage inputs and outputs, which allow compatibility with modular synths. Control voltages are routed from within the modulation matrix and run at audio rates for extreme modulation effects. “We wanted to make the Pro 3 as flexible as possible,” said Smith. “The CVs and deep mod matrix make it a mini modular in its own right — without all the patch cables.”

Sequential is also offering the Pro 3 SE, a special edition version of the synthesizer that puts the same synthesis power into a collector-worthy design that features a tilt-up control panel and full, premium-grade walnut trim.

The Pro 3 standard edition will be available at the end of January with a US MAP of $1,599.

The Pro 3 SE will be available in February with a US MAP of $2,099."

They often sit along side one another, but never do they replace each other.... The most common problem with the Pro-One is the goofy, clunky keyboard. The keys go out of alignment and become uneven. This one is no exception. This IS a snaggle toothed Pro-One. There are also two stickers on the back. One is "Tony Banks" and the other is "Le Car". They are really cool stickers and show that you are musically diverse.

E&MM Spectrum Synthesiser Preview

Published on Oct 20, 2019 Reuben Jones

"The E&MM Spectrum is a British DIY synthesizer designed by Chris jordan and released with Electronics and Music Maker magazine in 1981.....

The magazine provided a painted metal faceplate, keyboard assembly, and printed circuits boards. The rest was sourced by the builder using a supply kit provided by the now defunct Maplin Electronic Ltd, UK (see also the Maplin/ETI 3600, 3800, 4600, and 5600S synthesizers).

The synthesizer uses the famed Curtis integrated circuits: VCOs (CEM 3340), VCF (CEM 3320), VCA (CEM 3330), and envelopes (CEM 3310). These chips were used by many companies at the time, including AKAI, ELKA, Ensoniq, Oberheim, Roland, and Sequential Circuits.

Perhaps the closest synthesizer to the Spectrum is the Sequential Circuits Pro~One, both of which use the same CEM chips for VCOs, filter, and envelope; and use a similar two-VCO architecture. However, whilst the Pro~One is known for an extensive modulation section, the Spectrum is very interesting in its own right.

The design makes the most of the CEM 3340 VCOs, with a total of five waveforms, including a SUB square wave. The LFO, with multiple waveforms including random and regular sample and hold (the latter of which produces more defined sequencer like voltages), can be routed in positive or negative polarity to the VCOs, filter, ringmod/noise, and output. The multimode LP, LBP and BP filter is a self oscillating one and can be modulated by the joystick, envelope generator, and the LFO. There are also two sync options, as well as FM, ring mod, and an envelope shaper. The stereo output can also be modulated for panning and stereo FX; and there are eight jacks for external connectivity including CV/Gate in and out, and pre filter in.

In conclusion, I would describe the Spectrum as a drunk and wonky Pro~One. Mine is temperamental, and sometimes has a mind of its own, but when tamed, the Spectrum becomes a very live and organic synthesizer. The tech who serviced it for me said it reminded him of an ARP 2600, and described it as a 'proper synth'. GreatSynthesizers.com describe it as "...a mixture of EMS Synthi, Sequential Pro-One and Roland SH-5" and "one of the most outstanding monophonic analog synthesizers in history".

This audio was recorded directly from the Spectrum in mono, using a TC Electronic Alter Ego delay pedal for some parts. All parts played from the keyboard, or using the LFO to gate the amplifier."

Sequential Circuits Pro One

Details:
"From the manual:
About the Pro-One
The Pro-One is a monophonic (one-voice) keyboard synthesizer. Its principal sound sources are two voltage-controlled oscillators (VCOs), referred to as OSC A and OSC B. OSC A, OSC B, and a white noise source can be mixed into the resonant low-pass filter (VCF). The filter modifies the voice timbre under control of its four-stage envelope generator. The filter may also serve as a sound source. This stage is followed by a voltage-controlled amplifier (VCA), which shapes the voice amplitude also under control of a four-stage envelope generator. The keyboard provides frequency control voltage (KYBD CV) for the oscillators and filter, and generates a GATE which controls the envelope generators.

In addition to this basic voice, the Pro-One has extensive modulation provisions. Three modulation sources are available: the filter envelope generator (FILT ENV), OSC B, and a separate low-frequency oscillator (LFO). Each can be mixed and routed for either DIRECT or WHEEL-controlled modulation of five destinations: OSC A frequency (FREQ), OSC A pulse- width (PW), OSC B FREQ, OSC B PW, and filter frequency (FILTER).

This complement of analog synthesizer modules and the routings provided for their interconnection have been well-proven in the Pro-One's ancestors, the Prophet-5 and Prophet-10 polyphonic synthesizers. Besides allowing the synthesist to play up to five or ten notes at one time, these two instruments contain microcomputers which program all the control settings comprising a sound. The Pro-One is neither preset nor programmable: you always "patch" the precise sound you want with the knobs and switches on the control panel. But the Pro-One voice itself is identical to a single Prophet voice, so it is capable of as much range and expression.

Possessing the Prophet's sound and all standard monophonic synthesizer features, the Pro- One's own microcomputer makes possible innovations unheard of on a lowcost synthesizer; a 40-note sequencer, an arpeggiator, keyboard modes such as single- or multiple- triggering, and the unique automatic glide feature. An audio input with preamplifier and automatic GATE generator allows synthesizer processing of low-level inputs such as a microphone or electric guitar. The audio output can drive a monophonic or stereo amplifier, or stereo headphones. Of special interest to computer enthusiasts, the Pro-One readily interfaces for control by an external microcomputer."

I love the introductions for synths in manuals. You get a glimpse of how the people behind the synth wanted users to perceive it - it's the culmination of all the work that went into the synth. Introductions to manuals were one of the first things I put up on the old Matrixsynth site back in Oct of '97. Click on the nostalgia link when you get there to see them.

Yazoo - DON'T GO - Re-created w/ Sequential Circuits Pro-One Synth

Published on Jul 23, 2014 peahix

Another one from Pea Hicks. Don't miss the Yazoo Only You cover, and his Yamaha CS-01 Depeche Mode covers. Click here for all posts featuring peahix.

"By special request, here's another Yaz track re-created w/ the Sequential Circuits Pro-One synth. The original actually has a fair amount of ARP 2600 in it, which means that the sounds in my version are a bit hit-and-miss, but I was able to get reasonably close with most of the sounds. My starting point for this was four patches posted at http://www.unease.se/proone.htm which I modified to get closer to the original sounds. The kick is the same patch from the Vince Clarke magazine article that I used on "Only You." All the other sounds I programmed from scratch. Everything was sequenced in Cubase, and the Pro-One sounds were recorded one at a time via a Kenton Pro Solo MIDI/CV interface.

Note that, as with 'Only You,' the original recording is actually pitched a bit sharp. I've decided to record my versions at concert pitch (A440) for the sake of keeping things standard.

The snare, clap (heavy reverb), and hi-hat (heavy flanging) are all 808. The kick and toms are Pro-One.

For the record, I don't view these re-creations as "covers" or creative projects. They're more like jigsaw puzzles to me. A way to challenge my ear, a way to find out the limits of my limited gear, and a way to try to get into the head of musicians/producers I admire. Otherwise, they're relatively pointless and aren't meant to be creative statements in and of themselves.

Here you can download my midi file and patch sheets if you want to have a go and make your own version. Just let me know and give me a mention if you post your version anywhere. https://www.dropbox.com/s/s5342gtfi6o...
