"Just a quick run through of sounds (mostly created by me) on my T8. Sorry no speaking, or maybe that's a blessing? Rig is T8 mono out into summing amp then into Mac linein, recorded on Quick Time. If I was speaking, I'd be making the point that the T8 does sound fat and lovely - almost all the sounds in the demo are Single (and therefore 8 note poly). I'd also make the point that the expressiveness of the keyboard makes it quite an exceptional synth. First sound is left bank 77. After that Right bank 37, then it just works through right bank starting at 12 and ascending mostly sequentially. You'll notice a couple of sections in the vid where I obviously demo the aftertouch and show 2 keys (both Cs) that are a bit dysfunctional. You'll notice they require a bit of extra pressure and accuracy to play. Recording is completely dry, so a bit exacting on the keyboard technique, especially as I'm kneeling down playing this! Anyway, hope it gives an idea of how good a T8 really sounds and how versatile it is."

"The Prophet T8 is a legendary polyphonic analog synthesizer. It's widely considered the greatest instrument ever produced by Sequential, and "one of the best built analog synthesizers of all time."

This unit is especially unique, as it is the personal instrument of Steve Salani, the original hardware designer of the T8! This is your opportunity to own one of the rarest and most historic electronic keyboards of the 20th century.

The 76-note wooden keyboard action resembles that of a fine crafted acoustic piano, and offers adjustable velocity and polyphonic pressure sensitivity that captures every nuance of your performance.

The 8-voice Prophet T8 offers four keyboard modes: single, double, unison, or split. The instrument retains the characteristic sound of the famous Prophet 5, and includes 128 patches that feature dynamic response to velocity and pressure.

Each voice consists of two oscillators, a filter, VCA, noise source, and two ADSR envelopes. The versatile polyphonic modulation features expand the sonic capabilities of the instrument. There's even a built-in sequencer with variable playback speed!

This instrument has been safely stored in a smoke-free studio and is in excellent condition. It is configured for operation on 110V power. It will ship inside a high-quality A&S padded road case (see photos) and includes a power cord (the keyboard stand is not included). The instrument is still supported by winecountrysequential.com, who sell manuals, documentation, and some parts."

Division 6 CEM3340 VCO & Business Card Sequencer

Published on May 17, 2020 matrixsynth

Update: crazy little noodle added above. Description: "I don’t know what this is, but it sure is fun. Division 6 CEM3349 VCO oscillator sweep, Malekko Richter Oscillator II sequenced by Division 6 Dual Mini Sequencer and Tiptop BD808 and SD808 triggered by Z8000 Matrix Sequencer/Programmer. Noisering modding the Oscillator II for a little added grit. All through Mattson Mini Modular JP VCF and finally TC Electronic M300. Peeeeew!!! Kidding aside, listen to how low it goes with decent speakers. The CEM3340 was used in the Moog Memorymoog, Oberheim OB-Xa, Octave Voyetra Eight, Roland SH-101, MC-202, Jupiter-6, MKS-80, Sequential Circuits Prophet-5 10 & T8, Pro-One, Prophet-600, Banana Poly Synth, Crumar Spirit, Synton Syrinx, and more. See for yourself here. The Curtis CEM3340 was re-issued in 2016."

A few pics of a surprise package in the mail the other day. :) A Division 6 CEM3340 VCO & V2 update chips for my Business Card Sequencer. Pics of them in the rack below. Looking forward to giving them a run through.

via this auction


"Sequential Circuits Prophet 600 in excellent condition and in perfect working order. The celebrated little brother of the Prophet 5 and the first commercially available synth to feature MIDI functionality, the P600 model is an incredible value, retaining the rich tonal quality and much of the functionality of the Prophet 5.

The P600 has two oscillators per voice with sawtooth, triangle, and variable pulse waveforms. The oscillators can be individually tuned or synced together. Similar quality VCF and VCA sections from the Prophet 5 can be found here too! The P5's Poly-Mod section has also been passed onto the P600. An extremely versatile and easy to use synth, highlights of the P600 include the onboard arpeggiator, two-track sequencer and poly-modulation. The P600 is great for creating analog effects, swells and drones, and additionally boasts a glide effect and very flexible modulation possibilities.

The synth has been freshly serviced and thoroughly tested, and all functions and features work as intended. There's only very light wear on the solid wood ends framing the synth, and only a bit of additional light edge wear on the enclosure. All of the original knobs are intact too."

Sequential Circuits Prophet 600 SN 5537 w/ Original Box, Manual & Tape

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

Video in the listing previously posted here.

"For your consideration is the closest you'll find to a new-old-stock Sequential Circuits Prophet 600. As you can see from the pics, the synth looks as if it was never used, and according to the original owner, it pretty much hasn't. Also included is the original box and packing foam, the original preset-cassette, and the original manual. The original receipt of purchase is inside the manual, dating to 5/25/1985.
The synth was recently serviced by Analog Synth Service in Oakland, the top Sequential tech.
It is worth noting that there are small pockets of air under the touchpad, which can be felt and/or heard, but in no way affect the functionality of the touch pad. All buttons work properly.

About the P600:
Released in 1982, the Prophet 600 is the brother of the legendary Prophet 5 synthesizer, but has its own distinct character and sound. The Prophet 600 was also the first commercial synthesizer to implement MIDI and can store up to 100 patches in memory. The Prophet 600 features 6 voices of polyphony and has 2 oscillators per voice (VCOs - saw, triangle and pulse), oscillator sync, a low pass filter, 2 envelopes for VCF and VCA, arpeggiator, sequencer, glide and poly mod functions (to create FM timbres). The Prophet 600 is a versatile and capable analog synth and it excels at drones, pads, brassy sounds and cutting leads. The Prophet 600 "Gligli" upgrade also enhances it further with snappier envelopes, more LFO waveshapes, new arpeggiator functions, unison detune and more."

Rosen Sound Synth Demos & Restorations

Published on Jul 28, 2018 Rosen Sound

This one in via Soviet Space Child.

www.rosensound.com/rentals

Playlist:
1. Oberheim OB-X - Rosen Sound Demo

The OBX was the first major "answer" to the Prophet 5 synthesizer, and at least in our opinion, was the best answer anyone could've given.

The OB-X is based on the basic design of the (S)ynthesizer (E)xpander (M)odule also from Oberheim. Like the SEM, it features two discreet VCO's with saw and pulse, two envelopes, and the low pass section of the SEM filter. It also added noise, a release control, and cross modulation (similar to the Prophet's cross mod). The prophet's cross mod was a bit more dynamic, though. A flexible LFO section is also featured.

None the less, the OBX is in a species all of it's own in many ways. It's one of the very few mostly discreet programmable polyphonic synthesizers, and more than that spec, it sounds unique and absolutely marvelous.

Our unit features encore midi

Book your rental package with Rosen Sound and see the rest of our synth catalog at www.rosensound.com/rentals

2. Moog Minimoog - Rosen Sound Demo

3.SCI Prophet 5 - Rosen Sound Demo

In a lot of ways this needs no introduction. One of the most iconic poly synths ever made, and the first synth to offer true programmability with polyphonic architecture.

The Prophet 5 offers your basic amenities in a poly synth with 5 voices each with 2 VCO's, a low pass VCF, a VCA, two EG's, one LFO with multiple wave shapes available, with POLY MOD as the icing on the cake. This lets you make FM type sounds and is part of what makes the prophet 5 unique.

Our unit features factory midi

4. Oberheim Four Voice - Rosen Sound Demo

This in our opinion is one of the finest synthesizers ever made in terms of overall sound. The features are of course many and the synth as a whole is very flexible and powerful, but the sound it outputs is nothing short of mesmerizing.

The FVS features 4 Synthesizer Expander Modules (SEM) each representing a polyphonic voice. This means for one patch, each SEM must be setup identically. This may seem like too much, but it's actually a very enjoyable process that causes you to think different about the patch your making, the polarity of your modulation per voice, and subtle differences you can set.

The synth can also be used in a powerful unison mode, allowing each SEM to be adjusted separately for a crazy 4x dual oscillator synthesizer each with a multi mode filter to be fired at once.

Each SEM is as or more powerful than your standard mono synth, featuring 2 oscillators with saw and pulse each, PWM, FM, 1 LFO, two EG's, a bi-polar filter modulation control, and the sweetest Oberheim filter ever made featuring a bandpass filter and a sweepable LP-HP filter. These filters are special in the way that when the resonance is turned up, there is no loss of volume or low end.

Additionally, our FVS is an early model with no programmer (a feature loathed by many anyway). Instead, it features 2 dual mini sequencers with a common clock available. This means you can do 8-step 4 note poly sequencing between the four SEM's, or split the keyboard with one sequencer playing 1 SEM and 3 note chords on the other side of the keyboard.

Functionally, our FVS is very much in tune and has been stabilized to survive travel and tuning consistency. It is in tune as soon as it's turned on, and we provide a quick start guide for our rental customers to learn how to easily program and tune the machine.

Our FVS also features MIDI in via a modified YARN's module installed inside. This allows through basic midi and if desired (more complicated) midi scripts to play it polyphonically (default on boot), sequence each SEM assigned to a separate channel (enabling MPE), or played in Unison. All of these features can be harnessed by utilizing SYSEX or the Yarns editor, all which is provided on a thumb drive for rentals.

5. Moog Memorymoog - Rosen Sound Demo

To start, let's forget the internet-lore or an "unreliable" and "impossible to tune" machine. Our service shop is known worldwide for our work on Memorymoogs and stabilizing them for real production use.

Now, let's introduce you to (what we consider) the pinnacle of Moog synthesizers. With 3 oscillators + ladder filter per voice, flexible and intuitive modulation, and a knob per function, the Memorymoog is not a force to be reckoned with, and is in what we consider to be the top 3 best sounding synthesizers ever made.

From lush pads, 18 oscillator unison leads, heavy bass, and even gentle timbres, the memorymoog is sure to be a staple piece for your session in any genre on music. Plus it has everyones favorite feature: an arpeggiator!

Our rental memorymoog will arrive with an expression pedal and 12 custom patches (87-99) made by our resident in house programmer, Eli Goss. These 12 patches are the juice that will fuel modern productions to achieve sounds unobtainable by any other synth, with plugins not even worth a mention.

6. Oberheim OB8 - Rosen Sound Demo

One of our staple synths in the collection. The lore of the OB8 is that it's a less-exciting OBXa, however, with some choice mod's which we've done to ours, they are sonically identical.

The OB8 is one of the most flexible synthesizers available, which includes deep LFO routing from the front panel, and a PAGE 2 function that transforms every knob and button on the synth to do even deeper modulation, including quantized LFO's, musical "OBXA" style detuning, envelope routing, and more.

Additionally, our OB8 has been fitted with a Pratt & Read keybed, which brings the true feel of American poly synths to the experience, while also having the amenities provided by the B5 EPROM including factory midi.

7. Sequential Circuits Prophet 10 - Rosen Sound Demo

The Prophet 10 is more than just 2 Prophet 5's in one box; featuring an active EQ per voice, deeper modulation, and more performance capabilities with it's dual manuals and CV pedal inputs. This prophet 10 also features midi in and out.

8. Oberheim Four Voice Sequence

You could do an entire score with this #oberheimfourvoice. With quad poly sequencing and split modes the sky is the limit. Available for rent through us! Contact us for rates and availability. And yes, it has midi!

"For sale is a vintage Prophet-600 that is in mint condition. This 6-voice MIDI polysynth has 2 oscikllators (VCOs) and a resonant low-pass voltage controlled filter (VCF) in each of its 6 voices. In other words, it contains a total of 12-VCO's and 6 VCFs. The Prophet-600 uses the same Curtis IC chips (CEM3340 VCO ICs and CEM3372 VCF/VCA ICs) that were used in Sequential Circuits' flagship synth, the Prophet T8. The Prophet-600 also contains a built-in arpeggiator and a polyphonic sequencer with 2 memories. Like the Prophet-5 and the Prophet T8, the Prophet-600 contains a Poly-Mod section for frequency modulated (FM) effects. It has 100 programmable presets that can be stored on a cassette tape, a CD, or a PC. Presets are stored and/or loaded via the Tape In/Out jacks. I suggest you search the Internet if you need more information on the Prophet-600.

SPECIFICS
*This synth is 100% Functional. (Everything works as if it was brand new including all controls, pots, switches, LEDs, & input/output jacks.).
*The electronics is 100% Functional. All VCO's, VCFs, ADSR's, VCA's, LFO's, etc work as they should.
*The touch pad (membrane switches) works like new.
*The keyboard action is like new and all keys are in alignment. All 61 keys are functional and none of them stick.
*This synth is in immaculate cosmetic condition with no noticeable dings, scratches, or blemishes.

I purchased this polysynth from Wine Country Sequential in 2005 where it was restored and re-calibrated to factory specifications. Since it has only been used for occasional studio use, it remains in excellent condition."
