It was the first model in the Sound Canvas series and one of the earliest MIDI hardware sound sources to implement the GM standard. The SC-55 mkII, released in 1993, was an upgraded version of its predecessor, primarily increasing the polyphony (24 vs 28) and adding a PC interface (similar in specifications to the Mini Din8 PC Interface). anonymous@undisclosed.example.com (Anonymous) Fri, 12 Jun 2026 02:30:32 +0000
