Sequential Circuits Prophet T8

Sequential Circuits Prophet T8 Image

A monstrous 8 voice polysynth from SCI! The T8 has a very fat Prophet-5-like tone. This synth adds many illustrious new features (for its time) such as full MIDI implementation, 76 full size weighted keys with velocity and aftertouch, split/layer double/unison keyboard modes, and a simple but useful real-time sequencer. The new keyboard features many dynamics enhancements, ie: aftertouch can affect pitch, level, filter or the LFO. It was Sequential's finest analog synthesizer. Digital control of analog sound with an extremely flexible, intuitive and beautiful design - right down to the wood panels!

Unfortunately the T8 suffered from the popularity of the much cheaper Yamaha DX7 back in 1983 when they were released. Although it still sounds great, the weighted keyboard is the T8's best feature making it the Rolls Royce of analog synthesizers. Generally these beasts are hard to find today and still very expensive. It has been used by Howard Jones, the Thompson Twins and Steve Levine.

Overate beyond belief. It looks massive but doesnt live up to its look. I had one for 4 years and had to oppurtunity to exhange it for a Jupiter 8 and TR808, never looked back.

I’ve had my T8 for a few months, and I too was initially put off by the lack of snappiness. I decided to forget all that and focus on what it is rather than what it isn’t. It is the most expressive synth I’ve played. The action is light and responsive with a lovely delicacy. Playing requires finesse; programming requires sensitivity to purpose. Dedication is needed, but the payoff is huge. This is a true musical instrument. Warm and thick, expressive and soulful; it takes time to learn. This synthesizer separates the musicians from the players. It would have been an even more expressive instrument if independent amount values could be applied to poly AT routings. Lack of Local Off in Rev. 3.8 is a nuisance, but that’s all. The T8 is a great, deeply moving organic instrument I look forward to working with every time I sit down at the rig. I feel privileged to own one, and it’s probably underrated mostly because of the finesse factor required by those who would wield it.

A glorious thing of beauty. The most musical synth in my studio.... sure, the envelopes don't come near the speed of a Prophet 5 but that misses out what really makes the T8 a king amongst keyboards. I love it, slouchy envelopes and all....

This instrument was the "core" of Joe Zawinul's mighty synth rig from his last bunch of tours (The Syndicate stuff). In videos it seems to be trigging sax section samples, but who knows what other tricks Joe had up his sleeve?

Ive owned one of these, i brought it over from newy york back in 2002 it was a very strange peice of gear and nothing like as powerful as a prophet 5. envelopes are software and laggy.
It hasnt got the same voice structure as a prophet 5, and it sounds more like a beefed up prophet 600, i swapped it for a vgc jupiter 8 and mint TR808 and never looked back. I wouldnt have another given to me. The keyboard made a lovely master controller though.
A rare synth, but seriously overated, The layering features are cool though and make it capable of some impressive pads and such like.
