Description
The T8 has the same VCO configuration and filtering as the Prophet 5 with a welcome addition 8-note polyphony. The unique Sync function, which allows oscillator B to modulate the filter, frequency or modulation width of oscillator A. Oscillator B has a triangle waveform that was not on the Prophet 5 but both instruments have a triangle wave in Oscillator B. Additionally a knob in the LFO mod section gives control of the initial LFO modulation. New features like polyphonic glide and programmable volume , as well as digitised envelopes while still keeping the Oscillators themselves analog. The T8 has two processors with the keyboard scanning run by a Z80 CPU, while the synth itself was run by (routing, presets, envelope generation, and sequencing) the then newer Z8000 CPU.
