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.

The Prophet T8 is the best synth, I have ever played. Its dynamic is fantastic and you can controll "everything" only with the pressure of your fingers. I could compare it to severel other synths (look at but none of them is within the same high class. Sometimes it sounds a bit like a Jupiter 8. But the JP8 is more aggressive and colder. T8 can also sound aggressive, but even then it is a warm sound. The T8 is not wild and bad, it is majestic and magical. If you can get one, get one. It will change your hole (musical) life. Honestly.

A Prophet T8 was used by Tears for Fears on 'Songs From The Big Chair', MIDI'd up to a Yamaha DX7, alongside a Roland Jupiter 8 and Fairlight CMI.

What a temperamental git the T8 is. Capable of a nice sound but that old micro-processor controlled keyboard does not age well, I had to use an external controller kb to get it to work properly, then it sang.

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.
