1983 also saw the release of the Prophet-T8, which featured a 76-note wooden keyboard (uneven A to C), and implemented a basic MIDI interface. It had an eight-voice architecture that was similar to that of the Prophet 5. The weighted, velocity and aftertouch-sensitive keyboard was so well received that New England Digital adopted it for use in their Synclavier workstations. Dave Smith himself keeps a T8 unit as the main controller keyboard in his home studio.
"SCI Synthesizer. The T-8 is a touch-sensitive 8-voice polyphonic synthesizer from Sequential Circuits. It has a 76-note keyboard (A to C) that is both velocity- and pressure-sensitive. the keyboard is built of wood and has a weighted action. Velocity sensitively is adjustable and has been incorporated in the ADSRs, which give you touch control of each parameter of teh ADSR. Release time can be controlled by the velocity that the key is let up with. A poly-mod section provides additional flexibility by routing the velocity-controlled envelopes to other destination such as the oscillator frequency or pulse width. Each key as an independent pressure sensor. This second touch can be used to control the frequency of oscillator banks A and B, the pulse width of oscillator banks A and B, the filter, amplifier, LFO amount, and LFO frequency. The unit's eight voices (two oscillators per voice) are assigned according to four different keyboard modes: single mode, which sounds eight voices across the entire keyboard; double mode, which blends two different programs into four voices; split mode, which divides the keyboard and allocates four voices to each side of the programmable split point; and unison/track, which combines up to eight voices on one note (these voices may be either the same pitch or arranged in a chord composed of up to eight voices). A built-in real-time sequencer is provided with a memory capacity of over 600 notes. The sequencer also remembers all velocity information. The unit also includes a new envelope mode called ADR that sets the sustain to zero for creating more natural percussive envelopes. Both ADSRs have two programmed release settings. the second release is selected with either the second release switch or the release footswitch. the mod wheel can be programmed for an initial setting with the initial amount control. The unit weighs less than 60lbs. Price is $5,995.00. Sequential Circuits, 3051N. First St., San Jose, CA 95134." |
