SY77
From Wikipedia, the free encyclopedia
Yamaha SY77 is a 16 voice multitimbral music workstation (synthesizer) utilizing Realtime Convolution and Modulation Synthesis (RC&M). The convolution synthesis takes place by emulation of analog filter operation, filtering the AFM and AWM2 elements in a voice. Eight filters can be controlled by dedicated envelope generators. SY77 is equipped with 61 key velocity, aftertouch keyboard and has a large LCD display located above the keyboard. Programming takes place through a keypad on the front panel of the unit. The unit can generate rich, layered, multitimbral sounds very characteristic to the FM synthesis. There are large libraries of patches and expansion cards available for TG77 that allow for expansion of tonal capabilities of the unit. The unit came into production in 1989 and was designed and manufactured by Yamaha Corporation.
