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.

It has polyphonic aftertouch internally, but only outputs channel aftertouch via midi. What you can do is put it in midi Mono mode by pressing Record+6. Then each of its eight notes gets its own separate midi channel (and channel aftertouch command). For instance, I set up my Yamaha EX5 in Performance mode, assigned eight difference copies of the same patch to eight different patch locations and pointed the first eight Performance channels to those voices. It's a convoluted setup but works just like poly aftertouch! The Sustain command was still an issue, fixed that with a Midi Solutions box.

Several comments mentioned Joe Zawinul's use of the T8. It's the centerpiece of his rig in a rare and fascinating home-rehearsal video. Search for "Joe Zawinul in rehearsal 1985" on YouTube. In the video, he also uses a Chroma Polaris (with Expander), Prophet 5 and Korg DW-6000, but his hands are on the T8 most of the time.

This synthesizer contains the keyboard which NED decided to use in the Synclavier because Sequential did such a good job of it...

@sj. Given this synth is so rare I don't think anyone would take offence to someone posting details of one for sale
