Eventide Audio Bringing Back Laurie Spiegel’s Music Mouse After 40 Years
At the 2026 NAMM Show, Eventide Audio announced that it is working with electronic music composer Laurie Spiegel to bring back Music Mouse – an algorithmic musical composition application and performance instrument – after 40 years.
“Music Mouse is an intelligent instrument,” notes Spiegel. “It’s like having a composer as your partner.” Music Mouse translates mouse-controlled cursor movements into notes, harmonies and more.
Here’s an example of Music Mouse in action, via jonmerel:
Eventide says that it plans to re-release Music Mouse later this year, “carefully preserved and prepared for modern systems, without changing what made it special.”
The application was originally released in the mid-’80s for Mac, Amiga & Atari systems. Spiegel’s vintage Music Mouse site is still available via the Wayback Machine.
