The SY22 is a vector synth that uses an engine that combines 2-operator FM and PCM synthesis. The joystick is used for morphing between sounds and this unit is particularly well-suited to creating pad sounds.
It is similar to the Korg Wavestation, but the Wavestation does not do FM synthesis. The SY35 is a version with higher-resolution waveforms and a slightly different sound set and the TG33 is a tabletop module in the same series.
It has been mistakenly reported that the SY22 has a thin, metallic sound. While it is capable of producing those sounds with its FM engine, it is one of the richest, most beautiful-sounding digital synthesizers ever produced. To take full advantage, you will need to program your own sounds. This is made much easier by its built-in random patch generation functions. It's also a good idea to pair it with an external effects processor.
Patches can be saved on an MCD32 or MCD64 memory card. There are also expansion cards available. They contain patch data but not waveform data.
