Yamaha SY99
The Yamaha SY99 is a synthesiser combining frequency modulation synthesis (branded as Advanced FM) and sample-based synthesis (branded as Advanced Wave Memory 2) and the direct successor to Yamaha Corporation, Yamaha's Yamaha SY77, SY77/Yamaha TG77, TG77. Compared to the SY77, it has a larger keyboard at 76 keys instead of 61, a larger Read-only memory, ROM with more in-built AWM samples, the ability to load user-specified AWM samples into on-board RAM, an upgraded effects processor (based upon the Yamaha SPX900 rather than the SPX50 or SPX90), and several other enhanced features. Specifications * Date produced: 1991 * Polyphony: 16 notes ("Elements") of AFM + 16 notes (Elements") of sample-playback (AWM2) * Voice Architecture: Each voice can have up to 2 AFM (6-operator) Elements polyphonically, or 4 AFM (6-op) Elements monophonically, plus up to 2 AWM Elements * Filter: 2 multi-stage, time-variant, with resonance and self-oscillation per Element * Sequencer: 16 tracks, ~27,000 n ...

Frequency Modulation Synthesis
Frequency modulation synthesis (or FM synthesis) is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The frequency of an oscillator is altered "in accordance with the amplitude of a modulating signal". FM synthesis can create both harmonic and inharmonic sounds. To synthesize harmonic sounds, the modulating signal must have a harmonic relationship to the original carrier signal. As the amount of frequency modulation increases, the sound grows progressively complex. Through the use of modulators with frequencies that are non-integer multiples of the carrier signal (i.e. inharmonic), inharmonic bell-like and percussive spectra can be created. FM synthesis using analog oscillators may result in pitch instability. However, FM synthesis can also be implemented digitally, which is more stable and became standard practice. Digital FM synthesis (implemented as phase modulation) was the basis of several musical instru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
