Looks Like a standard PC with dedicated music software, (Similar to Livestyler) that can play audio, Yamaha styles (In XG Format) and uses Sound fonts for the inbuilt sounds. (A format that was first introduced in the 90s)
As software based keyboards/modules have been around for years (The very late 90s was probably when it first started) there is nothing new bought to the table.
Always good to see what’s out there though?
