"Once synthesizers flooded the music industry in the '80s, music production effectively became an arms race of who could use the most cutting-edge sounds to produce a hit first. Conversely, new forms of music could practically be defined by their new sounds. The piano and organ presets were used in 1990s house music, beginning with Madonna's 1990 single "Vogue". The powerful Korg M1 was just the instrument for these times, providing a diverse set of sounds that helped forge diverse genres. When house music first took to the Billboard charts, tracks like “Show Me Love” by Robin S. and “Rhythm is a Dancer,” by Snap! hinged on the sexy, simple tone of the M1's organ preset. Madonna, as always, changed with the times and used the M1 to great success on her hit “Vogue.” Yet, somewhat hilariously, the most well-known example of the M1 doesn't even occur in popular music — the goofy slap bass sound used in the Seinfeld theme song was not played on a bass, but on the M1."
