The musical version of the popular video game, Astrosmash. And a fun, new way to learn musical notation. As musical notes fall from the sky in the pattern of a popular song, you must play the right keys to shoot them down. The faster you shoot down the notes, the faster you're learning to play your favorite songs!

DEVELOPMENT HISTORY:
The VP of Design & Development, Richard Chang, loved music-based games and toys; the ECS had a music synthesizer due to his pushing. This cartridge for the music sythesizer was based on his idea.


FUN FACT: 
This was the only cartridge released for the ECS Music Sythesizer.

Marketing kept pushing this as a musical version of Astrosmash, and in early catalogs even called it by the name Astromusic.
