The accompaniment controls consist of an "intro/fill in" button, a "synchro start on-off/ending" button, and the obligatory start/stop button. You can also layer two voices using the "Dual Voice" on-off button (great for improving/fattening the base sounds). Then there is the "sustain" button I was talking about earlier, and a "Harmony" control (adds harmonized parts to the right hands) - you can pick between Duet, Trio, Block, Country and Octave harmonized parts, very handy, especially with the jazz styles. A typical omission for keyboards of this era is the absence of an input for a sustain pedal - In its place, we find a "Sustain" on-off button on the front panel (I remember a similar setup on my very first digital keyboard, the Gem DSK-8). Even though the early sampling technology is a bit raw, certain tones are absolutely a joy to play, and several of them are very nice-sounding. Some of the synth string patches even exhibit a retro analog nature.

AWM, Advanced Wave Memory Stereo sampling is a sampling system, creating superb wave data that mirrors the sound and expression of the original instrument by using advanced digital technologies. It creates a unique, rich sound by using multiple waveforms.
