Josh Clos produced this documentary short about John Keston and his Gestural Music Sequencer or GMS.

Of the Gestural Music Sequencer, Keston says, “I’m considering releasing a beta version of the application in a few months. Soon afterward I plan to release the code as Open Source so that the application can be developed further by artists interested in creating music through gestural input.”

Anyone interested?

See the GMS tag at AudioCookBook for more details.
