The Yamaha CS-80, modelled chip by chip from the service manual.
Tyrell80 rebuilds the CS-80 from its circuits. Each stage of the voice was modelled from the original service manual, then put together as a modern instrument.
It has two full voice channels, a ring modulator, sub-oscillator, touch response and the ribbon controller. The brass swells, the aftertouch breathes, and the strings hang in the air.
“It took four men to carry it upstairs. Now it takes one click.”
