YAMAHA SY77 Music Synthesizer Keyboard

Advanced Wave Memory Second-generation Advanced Wave Memory (AWM2) offers unmatched sample playback quality. Advanced Frequency Modulation Advanced Frequency Modulation (AFM) provides a dramatic boost in FM sound quality and programming versatility. Realtime Convolution & Modulation Realtime Convolution & Modulation (RCM) achieves a new fusion of sample realism and the expressive power of FM. Extensive Sample Layering SY77's versatile 1, 2, or 4-element voice architecture and complex envelope generators provide extensive sample layering capabilities. Advanced Digital Filters Advanced digital filters provide dynamic timbre control. Programmable Envelope Generators Multiple complex programmable envelope generators are featured. Dynamic Panning Dynamic Panning for sonic animation. Programmable Aftertouch and Assignable Controllers Key velocity and after-touch pressure can be assigned to control pitch, filtering, AWM2 modulation level and/or a range of AFM parameters. Assigned parameters can be controlled in a positive or negative direction. There's also an extra assignable center-detented wheel and several assignable controllers in addition to the pitch and modulation wheels. Internal Digital Signal Processors Four internal digital signal processors provide essential ambience, two for reverb effects and two for modulation. Display and Data Entry Controls Intuitive programming is provided through a user interface consisting of a 240 x 64 dot backlit liquid crystal control panel that makes several parameters visible at the same time. Flow diagrams and bar graphs displayed in graphic form provide instant recognition. A directory helps you locate functions and a unique "jump" number system allows direct switching between related functions. "Smart" function keys makes it easier to move around the programming environment.
