Sequential Circuits Prophet 10

Sequential Circuits Prophet 10 Image

This rarely seen monster analog synth is by far one of the fattest and nicest vintage synthesizers. The Prophet 10 is simply two glorious Prophet 5 synthesizers stacked together. That gives 10 voices with 20 of Sequential's unique analog VCO oscillators at 2 per voice for a big fat analog dream! The Version 1 series suffered from major overheating and unstable tuning problems making it clumsy and unreliable to use. It also had a standard 61 note keyboard and looked just like the P5.

Then came a bigger and better looking stacked keyboard version (as seen above); to be known as Version 2. Better chips were designed which soon cured most of the overheating problems. While Rev. 1 & 2 Prophets used chips made by SSM (Solid State Microdevices) which were fatter sounding but less stable, the Rev 3 Prophets changed to CEM (Curtis Electronics Manufacturing) chips. These increased their stability and reliability. Some audiophiles think they sound thinner than the SSM chips. However tuning and other functions were still somewhat unstable.

Version 3 (pictured top) was by far the best and most stable. 20 oscillators (2 per voice), 10 voices, 2 independent 61 note keyboards and all the great sounds and editing facilities as the Prophet 5! Built in Tuning tones and Auto-Tuning functions help make sure you won't go out of tune. And top notch circuitry and design prevent overheating. Multiple keyboard modes allow for true flexibility for different performance / voicing needs! The Prophet 10 is a truly fat and classic analog instrument. Used throughout the 1980's and on into the 90's by names like Tangerine dream, The Orb, The Who, the Pet Shop Boys, Vangelis, Genesis, the Human League, and filmmaker/composer John Carpenter.

I've owned my Prophet-10 since about '87, and have enjoyed every moment I ever spent on it. I always Loved the sequencer; that was really the icing on the cake for me. I thought about selling it a few times, but I still have it. :-) I hope to send it out to Wine Country at some point, and bring it back to its former glory, but it's a heavy [beep] er, especially with the road case. A very musical and beautiful creation.

It is definitely NOT just two P5's strapped together, btw. :-)

Is there a Prophets Anonymous group ? :-D

back in the day (approx '84) i had the means to get some high end synths - it was between oberheim , moog and sequential.i never once considered getting anything by roland or korg as the sound quality was truly feeble compared with the best.i ended up getting 2 prophet 10s.
the poly seq. is never brought up but it was a joy to create a bunch of mini-seqs then hold an empty bank and just punch in the the other banks in the order wanted creating long syncable seqs full of patch changes etc.-clever use of the single,double and alternate voice modes gave deep possibilities-much more than 2 p5s!

There is one for sale in Las Vegas, Nevada (United States) right now for $6000 (United States Dollars), supposedly excellent condition.

Great machine! Like all of the Dave Smith / Sequential machines, fantastic sounds and you can do a lot with it. Haven't had my hands on one on years, so I make do with my PolyEvolver for the Dave Smith sounds. If I ever stumbled upon one of these it would be in my studio the next day!
