SY77

A synthesizer that became widely popular among professional musicians.
The SY77 features a digital filter that can mimic the behavior of an analog synthesizer, which doubles the expressiveness of the two built-in digital tone generators (AWM and FM). The augmented tone generators became known as AWM2 and AFM, respectively.
The SY77 is also equipped with a multi-timbre function with the expressiveness of 16 synthesizers, and a 16-track sequencer capable of handling MIDI on all channels.
