"Vintage Sequential Circuits Prophet 10 Dual Manual Keyboard Synthesizer with Flight Case This Prophet 10 is in very good condition, and is fully functional, although the Braemer tape drive has not been tested. Has factory MIDI and sequencer, and the original blue Prophet-10 flight case on wheels. This may be one of the last Prophet-10s made, as the S/N is 0444. It's big and heavy!! Includes power cord, electronic copies of the operation manual and service information, and one original Sequential footswitch. The flight case foam is serviceable, but could use replacement. The synth is wrapped in plastic within the flight case. Full pictures are here [captured below]. By far the most prevalent of the original Prophet 10 models, the Prophet 10 Rev3 was a better built version than the previous 2 iterations for more consistent and reliable performance. It used Curtis Electronics Manufacturing chips, and featured 2 VCOs per voice, a low pass resonant filter with ADSR, LFO, & cv/gate controls. This rarely seen monster analog synth is by far one of the fattest and nicest vintage synthesizers.

Another Vintage Analog Synth Jam
video upload by Reuben Jones
"A simple jam I made a while ago and uploaded to Instagram (@reuben0jones). Now on YouTube.
The Tempest, apart from doing drums, is clocking both the PolyEvolver making the digital sounding effects, and a Tanzbar which is simply clocking a sequence on the ARP Sequencer and sending CV/Gate to the Pro~One which is sending CV back to the ARP Sequencer so I can change key on the Pro~One's keyboard. At least I think that's how I did it. Korg MS10, Logan Vocalist and Octave Kitten 2 are played on top.

"P-10 is based on one of the most desirable flagship analog polysynths ever created, a dual-layer synth that was essentially two of the revolutionary P5s in one behemoth dual-manual case. P-10 exactingly reproduces all that is exceptional in this classic, including the original P5 and P10 factory presets. It also adds thoughtful updates to modernize the user experience, including expanded 16-voice per layer polyphony, velocity and polyphonic aftertouch, a four-track sequencer, keyboard split, an arpeggiator, and a complete effects section."

video upload by CatSynth TV
"We take a deep dive into the P-10, Cherry Audio's new recreation of Sequential Circuits' legendary flagship polyphonic analog synthesizer, the Prophet 10. Essentially two Prophet 5s in a single case with two keyboard manuals, it could be played as two separate voices or stacked together for massive four-oscillator-and-two-filter per voice sound. We go over all the features of the new P-10, as well as a few of the factory presets."

Cherry Audio P-10 is based on one of the most desirable flagship analog polysynths ever created. Released by SCI in 1980, the original instrument was essentially two of the revolutionary P5 programmable synths in one behemoth dual-manual case, plus a "poly sequencer" built into the bottom-manual end cheek. It could be configured to play as two independent five-voice synths, a single ten-voice synth, dual-patch layered, or alternating between layers with each keystroke.
P-10 exactingly reproduces all that is exceptional in this legendary classic, including the original P5 and P10 factory presets, while boosting its astonishing feature set for today's music production and workflow, and celebrating 50 years of groundbreaking innovation from the company that changed the music industry forever.

Sequential Circuits Prophet T8 Analog Synthesizer
Note: Auction links are affiliate links for which the site may be compensated.
video upload by Joseph McGinty
"A demonstration of the polyphonic aftertouch capabilities of the Sequential Circuits Prophet T8. Currently on sale on Reverb."
via this listing
"Purchased from Bell Tone Synth Works a few years ago who had completely restored it. It's in beautiful condition and sounds amazing. Though there are other poly aftertouch keyboards on the market now, none have the feel of the Prophet T8. It has the latest firmware update. Check out the video for a demonstration of the polyphonic aftertouch."
"Full MIDI implementation, 76 full size weighted keys with velocity and aftertouch, split/layer double/unison keyboard modes, and a simple real-time sequencer. The new keyboard features many dynamics enhancements, ie: aftertouch can affect pitch, level, filter or the LFO."
Features:
8 Voices, each with
– 2 VCOs
– 2 envelopes
– VCF
– VCA
LFO (0,005 – 40 Hz)

♫ Jamming With a Bunch of Synths ♫ ----- (79)
video upload by Bata
"This jam is a little weird. My phone was on low battery which made the video slightly glitchy. I was a bit distracted during this recording so it's maybe a bit more boring than usual. There is also a couple mysterious audio drop outs near the end of the video. I didn't notice these prior to uploading so it's possible something went wrong when combining the audio and video files or something.

Sequential Circuits Prophet T8 - 8-Voice Polyphonic Synthesizer SN 000024
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
"Selling my beloved Prophet T8 after many years of great recordings and cared use. This was serviced a few years ago by one of the best western Canadian synth technicians. Its fully function and the keybed has felt replacement recently and it feels great. Lots of information on the net about this amazing synthesizer. Its midi functionality is great and I used this as my main controller for my DAW instruments and other synths with midi. The built in real-time sequencer is amazing! Poly After touch, 8 Voice, Velovity envelope control! Its been called the Rolls Royce of Synths in the book 'A to Z of Analogue Synths' by Peter Forrest.
Its in excellent shape, some little dings and scratches on the metal here and there. Was like that when I got it. Its lived in my studio since purchasing over 10 years ago." [posted here]

Sequential Circuits Pro One
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
"The Sequential Pro One is a fantastic monosynth. This one is in great condition with little to no use by me ... had it recently serviced to get it up to snuff . It comes from the same period and genre as the Roland and Moog . The Pro One was basically Sequential's attempt at taking their legendary poly-synth and packing it into a compact monophonic analog synth. It has two VCOs, a great 4-pole lowpass filter, two ADSR envelopes (one for filter), and a compact three-octave keyboard. With a Pro-One, you can easily create punchy analog bass-lines and leads or quirky analog synth effects.
The Pro One is an extremely flexible synth with lots of modulation possibilities (ie: the filter, VCO B and LFO can modulate VCO A or B frequencies or pulse widths, or the VCF). There's also an onboard sequencer, something common on many Sequential synths but not often found on other monosynths of the time. Also onboard is an arpeggiator which has UP and UP/DOWN patterns."
