SY99

A workstation-style synthesizer equipped with an evolved version of the FM tone generator typified by the DX7, as well as the sampling-based AWM2 tone generator used on digital pianos and the like, and the advanced MIDI sequencing functionality improved throughout the QX Series.
This hybrid AFM/AWM2 system is known as an RCM (Realtime Convolution & Modulation) tone generator due to its capacity to change sounds using digital filters in response to key touches and other input.
