Marv is a MIDI Actuated Robotic Vibraphone.

Marv can play music of high complexity, far more complex than a human player could ever achieve, as Marv is capable of striking any and all keys simultaneously, as well as damping each key individually.  Marv can play much faster than a human vibraphonist, repeating single notes as quickly as 25ms apart.  Marv can play with sensitivity and feeling limited only by MIDI programming effort.  Marv is a platform for further research on musical automation and real-time musical interaction.

Marv was created by Tim O'Keefe, Michael McIntyre, and Brock Roland at the SFSU School of Engineering.
